The Grant Information Act of 2018 (Stats. 2018, Ch. 318) required the State Library to build one website by July 1, 2020, “that provides a centralized location … to find state grant opportunities.” State agencies provide all information on grants.ca.gov to the State Library for publication. The Grant Information Act requires state agencies to provide summaries of each of their grant or loan opportunities, including information about how to apply and links that grantseekers can follow for more details. *FYI* If you're not familiar with data.ca.gov, you can download the csv and find the API call by clicking on the "Explore" button below. *Note*: the data set updates every 24 hours at 8:45pm.
Hazardous waste identification (ID) numbers are issued by the U.S. Environmental Protection Agency (Federal EPA ID number) or by the Department of Toxic Substances Control (California State ID number). The ID number identifies each handler of hazardous waste on hazardous waste manifests and other paperwork. The ID number enables regulators to track the waste from its origin to final disposal, a process also referred to as “cradle to grave.” With a few exceptions, most hazardous waste generators must have an ID number before a registered hazardous waste transporter will accept their waste for shipment. All hazardous waste transporters and permitted treatment, storage, and disposal facilities (TSDFs) must have a hazardous waste ID number. For more information, please go to https://dtsc.ca.gov/hazardous-waste-id-numbers/.

The power outages in this layer are pulled directly from the utility public power outage maps and is automatically updated every 15 minutes. This dataset represents only the most recent power outages and does not contain any historical data. The following utility companies are included: Pacific Gas and Electric (PG&E) Southern California Edison (SCE) San Diego Gas and Electric (SDG&E) Sacramento Municipal Utility District (SMUD) Layers included in this dataset: Power Outage Incidents - Point layer that shows data from all of the utilities and is best for showing a general location of the outage and driving any numbers in dashboards. Power Outage Areas - Polygon layer that shows rough power outage areas from PG&E only (They are the only company that feeds this out publicly). With in the PG&E territory this layer is useful to show the general area out of power. The accuracy is limited by how the areas are drawn, but is it good for a visual of the impacted area. Power Outages by County - This layer summaries the total impacted customers by county. This layer is good for showing where outages are on a statewide scale.

COVID-19 Vaccine Progress Dashboard Data
__Note__: In these datasets, a person is defined as up to date if they have received at least one dose of an updated COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) recommends that certain groups, including adults ages 65 years and older, receive additional doses. On 6/16/2023 CDPH replaced the booster measures with a new “Up to Date” measure based on CDC’s new recommendations, replacing the primary series, boosted, and bivalent booster metrics The definition of “primary series complete” has not changed and is based on previous recommendations that CDC has since simplified. A person cannot complete their primary series with a single dose of an updated vaccine. Whereas the booster measures were calculated using the eligible population as the denominator, the new up to date measure uses the total estimated population. Please note that the rates for some groups may change since the up to date measure is calculated differently than the previous booster and bivalent measures. This data is from the same source as the Vaccine Progress Dashboard at https://covid19.ca.gov/vaccination-progress-data/ which summarizes vaccination data at the county level by county of residence. Where county of residence was not reported in a vaccination record, the county of provider that vaccinated the resident is included. This applies to less than 1% of vaccination records. The sum of county-level vaccinations does not equal statewide total vaccinations due to out-of-state residents vaccinated in California. These data do not include doses administered by the following federal agencies who received vaccine allocated directly from CDC: Indian Health Service, Veterans Health Administration, Department of Defense, and the Federal Bureau of Prisons. Totals for the Vaccine Progress Dashboard and this dataset may not match, as the Dashboard totals doses by Report Date and this dataset totals doses by Administration Date. Dose numbers may also change for a particular Administration Date as data is updated. Previous updates: * On March 3, 2023, with the release of HPI 3.0 in 2022, the previous equity scores have been updated to reflect more recent community survey information. This change represents an improvement to the way CDPH monitors health equity by using the latest and most accurate community data available. The HPI uses a collection of data sources and indicators to calculate a measure of community conditions ranging from the most to the least healthy based on economic, housing, and environmental measures. * Starting on July 13, 2022, the denominator for calculating vaccine coverage has been changed from age 5+ to all ages to reflect new vaccine eligibility criteria. Previously the denominator was changed from age 16+ to age 12+ on May 18, 2021, then changed from age 12+ to age 5+ on November 10, 2021, to reflect previous changes in vaccine eligibility criteria. The previous datasets based on age 16+ and age 5+ denominators have been uploaded as archived tables. * Starting on May 29, 2021 the methodology for calculating on-hand inventory in the shipped/delivered/on-hand dataset has changed. Please see the accompanying data dictionary for details. In addition, this dataset is now down to the ZIP code level.
COVID-19 Vaccine Progress Dashboard Data by ZIP Code
__Note__: In these datasets, a person is defined as up to date if they have received at least one dose of an updated COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) recommends that certain groups, including adults ages 65 years and older, receive additional doses. Starting on July 13, 2022, the denominator for calculating vaccine coverage has been changed from age 5+ to all ages to reflect new vaccine eligibility criteria. Previously the denominator was changed from age 16+ to age 12+ on May 18, 2021, then changed from age 12+ to age 5+ on November 10, 2021, to reflect previous changes in vaccine eligibility criteria. The previous datasets based on age 12+ and age 5+ denominators have been uploaded as archived tables. Starting June 30, 2021, the dataset has been reconfigured so that all updates are appended to one dataset to make it easier for API and other interfaces. In addition, historical data has been extended back to January 5, 2021. This dataset shows full, partial, and at least 1 dose coverage rates by zip code tabulation area (ZCTA) for the state of California. Data sources include the California Immunization Registry and the American Community Survey’s 2015-2019 5-Year data. This is the data table for the [LHJ Vaccine Equity Performance dashboard](https://public.tableau.com/profile/ca.open.data#!/vizhome/LHJVaccineEquityPerformance/MapView?publish=yes). However, this data table also includes ZTCAs that do not have a VEM score. This dataset also includes Vaccine Equity Metric score quartiles (when applicable), which combine the Public Health Alliance of Southern California’s Healthy Places Index (HPI) measure with CDPH-derived scores to estimate factors that impact health, like income, education, and access to health care. ZTCAs range from less healthy community conditions in Quartile 1 to more healthy community conditions in Quartile 4. The Vaccine Equity Metric is for weekly vaccination allocation and reporting purposes only. CDPH-derived quartiles should not be considered as indicative of the HPI score for these zip codes. CDPH-derived quartiles were assigned to zip codes excluded from the HPI score produced by the Public Health Alliance of Southern California due to concerns with statistical reliability and validity in populations smaller than 1,500 or where more than 50% of the population resides in a group setting. These data do not include doses administered by the following federal agencies who received vaccine allocated directly from CDC: Indian Health Service, Veterans Health Administration, Department of Defense, and the Federal Bureau of Prisons. For some ZTCAs, vaccination coverage may exceed 100%. This may be a result of many people from outside the county coming to that ZTCA to get their vaccine and providers reporting the county of administration as the county of residence, and/or the DOF estimates of the population in that ZTCA are too low. Please note that population numbers provided by DOF are projections and so may not be accurate, especially given unprecedented shifts in population as a result of the pandemic.
Groundwater Sustainability Plan Annual Report Data
The Groundwater Sustainability Plan (GSP) Annual Report (AR) datasets contain the following data submitted by Groundwater Sustainability Agencies (GSA) and Alternative Agencies as part of their GSP AR or Alternative to GSP AR: groundwater extraction, surface water supply, total water use, and change in storage volumes for a given water year. All data was originally submitted to the Department of Water Resources (DWR) through the Sustainable Groundwater Management Act (SGMA) Portal’s AR Modules (https://sgma.water.ca.gov/portal/gspar/submitted and https://sgma.water.ca.gov/portal/alternative/annualreport/submitted). Data records within each dataset correspond to either an entire basin or one of multiple GSP areas which collectively correspond to an entire basin. The GSP Regulations established the AR data requirements (23 CCR § 356.2) and tasked DWR with developing an online reporting system for GSAs and Alternative Agencies to electronically submit these data (23 CCR § 353.2). The data fields associated with these datasets were created by DWR to ensure GSAs and Alternative Agencies electronically submitted the required AR data to DWR’s online reporting system, the SGMA Portal (https://sgma.water.ca.gov/portal/). For additional information regarding the AR Modules and the AR submittal process, please view the DWR’s AR resources (https://sgma.water.ca.gov/portal/resources).

Drinking Water - SAFER Dashboard Failing and At-Risk Drinking Water Systems
The Division of Drinking Water (DDW) identifies Failing and At-Risk community water systems and K-12 non-transient, non-community schools. This information is displayed online in the Safe and Affordable Funding for Equity and Resilience (SAFER) Dashboard. The data utilized for this assessment is derived from multiple sources: self-reported from water systems, data generated by DDW staff, other California state agencies, and U.S. Census. The data sources, calculation methods, Failing and At-Risk criteria, etc. are fully documented in the annual Drinking Water Needs Assessment report which is published annually on the State Water Board’s website.
Needs Analysis Unit - Division of Drinking Water
The DWR Periodic Groundwater Levels dataset contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. This resource also included daily measurements from DWR's automated monitoring network of groundwater sites. For DWRs holdings of groundwater level measurements recorded at more frequent intervals (e.g., hourly), please refer to DWR's “Continuous Groundwater Level Measurements” dataset. For additional information regarding DWR groundwater levels data collection please visit DWR's Groundwater Management website (https://www.water.ca.gov/Programs/Groundwater-Management). The source data can also be accessed directly from two websites. The Water Data Library (http://wdl.water.ca.gov) provides anonymous access to this and other data sets. The CASGEM online system (https://www.casgem.water.ca.gov/OSS) provides authenticated access to only the the periodic groundwater measurements. This dataset is maintained primarily in the DWR Enterprise Water Management database and contains information specific to the location of groundwater level monitoring wells and groundwater level measurements collected at these wells. The Stations resource identifies well location coordinates and other supplementary items about the well type. Measurements resources includes information about the time/date a measurement was collected, the entity collecting the measurement, a measurement indicating the depth to groundwater, and quality information about the measurement. The Well Perforations resources contains well construction information identifying the well's screened intervals (not available for all wells).
The Groundwater Sustainability Plan (GSP) Monitoring dataset contains the monitoring sites and associated groundwater level, subsidence or streamflow measurements collected by Groundwater Sustainability Agencies (GSA) during implementation of their GSP. All data is submitted to the Department of Water Resources (DWR) through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM). The GSP Regulations established the monitoring network criteria (23 CCR § 354.34) and the data and reporting standard for monitoring sites and measurements (23 CCR § 352.4). The data fields associated with these datasets were created by DWR to ensure that GSAs electronically submit monitoring site and measurement data which meets the GSP Regulation’s data and reporting standards. For additional information regarding GSAs, GSPs, and SGMA related monitoring, please view DWR’s SGMA Portal Resources at https://sgma.water.ca.gov/portal/.
WIC Enabled Farmers and Authorized Farmers Markets
California farmers provide nutritious food s to families throughout the state, the nation, and the world. The California Department of Public Health/Women, Infants, and Children Division (CDPH/WIC) supports the consumption of fresh, locally grown fruits and vegetables, and encourages shopping with local farmers at community WIC authorized farmers’ markets. CDPH/WIC authorizes farmers and farmers’ markets for WIC Farmers’ Market Programs. These farmers are also automatically authorized to participate in the California Department of Food and Agriculture’s Senior Farmers’ Market Nutrition Program.
Women, Infants and Children (WIC) Authorized Vendors
This dataset contains the vendor name and location of all currently active vendors authorized to offer supplemental foods to participants for redemption with WIC food instruments and vouchers. The Women, Infants and Children (WIC) Program is a federally-funded health and nutrition program that provides assistance to pregnant women, new mothers, infants and children under age five. WIC helps California families by providing food instruments and vouchers that can be used to purchase healthy supplemental foods from over 4000 WIC-authorized vendor stores throughout the State. WIC also provides nutritional education, breastfeeding support and help finding healthcare and other community services. Participants must meet income guidelines and other criteria. Currently, 84 WIC agencies provide services monthly to over 1.45 million participants at over 650 sites in local communities throughout the State. For a mobile friendly site on WIC vendors and other WIC-related information visit: https://m.wic.ca.gov/
In California, water systems serving one (1) to 15 households are regulated at the county level. Counties vary in their practices, but rarely do counties collect data regularly from these systems. Even where data is collected, it is entirely voluntary. A review of well permit information suggests there are over 1 million such water systems in California. In early 2014, a cross-agency Work Group created an easily accessible reporting system to get more systematic data on which parts of the state had households at risk of water supply shortages. The initial motivation for local water supply systems to report shortage information was to obtain statewide drought assistance. The reporting system receives ongoing reports of shortages from local, state, federal and non-governmental organizations, and tracks their status to resolution. While several counties have developed their own tracking mechanisms, this data is manually entered into the reporting system. The cross-agency team, led by DWR, seeks to verify and update the data submitted. However, due to the volunteer nature of the reporting and limitations on reporting agencies, collected data are undoubtedly under-representative of all shortages to have occurred. In addition, reports are received from multiple sources and there are occasionally errors and omissions that can create duplicate entries, non-household water supply reporting, and under-reporting. For example, missing information or no data for a given county does not necessarily mean that there are no household water shortages in the county, rather only that none have been reported to the State.
CA Urban Retail Water System Water Loss Annual Loss Audit Data
This dataset contains annual validated water loss audit reports submitted to the Department of Water Resources by California urban retail water suppliers, as required under Title 23, California Code of Regulations Section 638.5(c) (Regulation). California Water Code Section 10608.12(af) specifies that urban retail water suppliers are those water suppliers directly providing potable municipal water to more than 3,000 service connections or that supply more than 3,000 acre-feet per year at retail for municipal purposes. The Regulation mandates that urban retail water suppliers with multiple separate potable water systems submit a separate audit for each system, regardless of system size. The dataset includes individual water loss audits for all potable water systems owned by urban retail water suppliers, including reports from water suppliers newly classified as urban retail water suppliers. While all submissions are available at the WUEdata.ca.gov portal, this dataset provides a cleaned version with only the latest submissions (older submissions that were corrected are not included). Water system boundaries for the water system water loss data in this dataset may be available in the Water Board's DDW California Drinking Water System Area Boundaries (SABL) tool. The link to this tool can be found in Additional Resources as part of this dataset. Water loss audits evaluate real water losses (leaks) and apparent water losses (e.g. data errors, water theft) occurring in a potable water distribution system. Estimating the scale and cost of these losses allows utilities to identify opportunities for saving water and recovering revenue. California water loss audit submissions were reviewed by validators and submitted to DWR starting in 2016. The reviews followed the validation methodology detailed in Water Research Foundation Project 4639: Level 1 Water Audit Validation. Level 1 water audit validation aims to: * Identify and, where possible, correct inaccuracies in water audit data and application of methodology. * Evaluate and communicate the uncertainty inherent in water audit data. The data is provided "as is" (as submitted by the water systems). More information on this dataset can be found in the file "Data Source and Notes" available at the on the home page of this dataset.

Bloom reports are voluntary reports submitted by the public or organization to identify a POTENTIAL HAB for evaluation. Bloom Reports may or may not include a report that is confirmed to be a HAB, regardless, all bloom reports are published. Due to the voluntary basis of information and data included in the database, data and information may include: waterbody name and location, potential algal bloom location and observed characteristics, observed field observations and/or analytical sampling results, waterbody and/or land management, general information, recommended advisory status (if any), and updates regarding bloom status. Refer to Data Dictionary and Data Disclaimer for additional information about this dataset. Please visit the Water Boards FHABS web site for more information and data visualizations https://mywaterquality.ca.gov/habs/index.html.
CDPH-Wastewater Surveillance Data, California
The California Department of Public Health (CDPH) is coordinating with wastewater utilities, local health departments, academic researchers, and laboratories in California on wastewater surveillance for infectious disease pathogens of interest to public health (such as SARS-CoV-2, the virus causing COVID-19, influenza, respiratory syncytial virus (RSV), mpox, and norovirus). Data collected from this network of participants, called the California Surveillance of Wastewaters (Cal-SuWers) Network, are submitted to the U.S. Centers for Disease Control and Prevention (CDC) National Wastewater Surveillance System (NWSS). Collecting and analyzing wastewater samples for the presence of, and amount of (concentration), a specified pathogen target can help inform public health about circulation of that infectious disease within a community. Data from wastewater testing do not replace existing public health surveillance systems but complement them. While wastewater surveillance cannot determine the exact number of infected persons in the area being monitored, it can provide overall trends of pathogen concentration within that community. Please note that data included in the Cal-SuWers Network and available here originate from multiple programs and laboratories. Methodologies for producing wastewater data are not currently standardized, and analyses, comparisons, and aggregations should be done with caution. Wastewater is a complex environmental sample and inherent variability in measured concentrations is expected due to environmental variability, day-to-day differences in sewershed and population dynamics, differences in the amount of shedding between people and pathogens, and laboratory and sampling variability. Please see the CDPH Cal-SuWers, CDC NWSS, and CDC Public Health interpretation and Use of Wastewater Surveillance data webpages for more information. Historical wastewater data can be found [here](https://data.ca.gov/dataset/covid-19-wastewater-surveillance-data-california).

Statewide Property Inventory started in 1989 per legislation 11011.15, to begin a pro-active approach to managing the State’s Real Property assets in a computerized format. Having the information in an electronic format makes it available to top level decision-makers considering options for the best use of these assets. The Statewide Property Inventory is mandated to capture detailed information on the following: land owned and leased by the state, structures owned and leased by the state, property the state leases to the private sector. Statewide Property Inventory was established in 1988 by legislative mandate. Leases were added in 2004 by executive order. Data is updated annually by the agencies.

Surface Water - Fecal Indicator Bacteria Monitoring Results
This dataset contains fecal indicator bacteria (FIB) monitoring results collected from surface waters across California. It includes results for _Escherichia coli_ (E. coli), enterococci, fecal coliforms, and total coliforms - key indicators used to assess microbial water quality and potential health risks associated with recreational water use. The data has been cleaned and standardized to ensure consistency and usability. For each valid data point, the dataset also includes calculated 6-week and 30-day geometric means, which are commonly used to evaluate long-term water quality trends and compliance with bacteria water quality objectives. Some records are excluded from the final dataset during processing. These typically include duplicate or replicate results, records with missing or invalid result values, or any data that cannot be used to calculate a geometric mean. These records are saved to the "Excluded Records" data resource. This dataset serves as the primary data source for the Water Boards My Water Quality Portal [Safe to Swim Map](https://mywaterquality.ca.gov/safe-to-swim/content/interactive_map/index.html), which provides the public with timely information about potential health risks associated with water contact recreation at monitored sites. Data is sourced from the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN) database, BeachWatch database, and the Central Valley Water Board [Lower American River Recreational Water Quality Map](https://experience.arcgis.com/experience/47e27f245e044ac2a8e15083307e75f6/?draft=true&org=waterboards). There is some overlap with the [CEDEN Water Chemistry dataset](https://data.ca.gov/dataset/surface-water-chemistry-results). Both portal datasets draw from the same source, but the resources here are updated more frequently to support the Safe to Swim map.
Eligible Individuals Enrolled in Medicare Savings Programs (MSP)
The datasets include the monthly count of individuals who are enrolled in Medicare Savings Programs (MSP), by aid code and county. The counts reflect the total number of eligible individuals enrolled during the month. MSP help individuals with limited income and resources pay for some of the out-of-pocket costs for Medicare, including Medicare Part A and Part B premiums, deductibles, copayments, and coinsurance. There are four Medicare Savings Programs: Qualified Medicare Beneficiary (QMB), Specified Low Income Medicare Beneficiary (SLMB), Qualifying Individual (QI), and Qualified Working Disabled Individual (QWDI). Individuals who are eligible for QMB, SLMB, and QI also automatically qualify for the Low Income Subsidy (or “Extra Help”) program, which helps lower the cost of prescription drugs. Counties and aid codes with zero individuals enrolled during a reporting period are not included in the dataset.

California requires that all local governments (cities and counties) adequately plan to meet the housing needs of everyone in the community. California’s local governments meet this requirement by adopting housing plans as part of their “general plan”. General plans serve as the local government’s "blueprint" for how the city and/or county will grow and develop and include eight elements: land use, transportation, conservation, noise, open space, safety, environmental justice, and housing. The Housing Element Compliance Report provides current Housing Element Compliance Status. Additional information about Housing Elements can be found on HCD’s website here: https://www.hcd.ca.gov/planning-and-community-development/housing-elements.

DWR has a long history of studying and characterizing California’s groundwater aquifers as a part of [California’s Groundwater (Bulletin 118)](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118 "California’s Groundwater (Bulletin 118)"). [California's Groundwater Basin Characterization Program](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "California's Groundwater Basin Characterization Program") provides the latest data and information about California’s groundwater basins to help local communities better understand their aquifer systems and support local and statewide groundwater management. Under the Basin Characterization Program, new and existing data (AEM, lithology logs, geophysical logs, etc.) are integrated to create continuous maps and three-dimensional models. To support this effort, new data analysis tools have been developed to create texture models, hydrostratigraphic models, and aquifer flow parameters. Data collection efforts have been expanded to include advanced geologic, hydrogeologic, and geophysical data collection and data digitization and quality control efforts will continue. To continue to support data access and data equity, the Basin Characterization Program has developed new online, GIS-based, visualization tools to serve as a central hub for accessing and exploring groundwater related data in California.

Remotely Sensed Evapotranspiration of agricultural lands in California
This dataset represents regional agricultural evapotranspiration (ET) in groundwater basins and counties derived from OpenET estimates. Monthly or annual ET depth and volume data are summarized for the OpenET v2.1 ensemble value from October 2003 to 2025. The OpenET v2.1 ET datasets are natively produced at a 30m spatial resolution were created using Landsat imagery on Google Earth Engine. The ensemble value was derived from six models. The description of six models and the ensemble value and their accuracy can be found at https://etdata.org. A California specific accuracy assessment https://etdata.org/impact-stories/advancing-groundwater-sustainability-with-california-dwr-openet/ provides additional information about OpenET data fidelity for key crop types and natural lands in the state (Volk et al., 2026). Packaged by County, Groundwater Basin, and Hydrological Region: The OpenET v2.1 evapotranspiration data has been packaged by state county, groundwater basin, or hydrological region to include data for all pixels that overlay three individual boundaries. The agricultural land mask was generated using the 2024 California Statewide Crop Mapping excluding urban lands and applied to all the years. Service/Hosted Location: 1. The original summarized tables and shapefiles containing data summaries can be found on GitHub: https://github.com/cgmorton/cadwr-basin-summaries. 2. The 30-meter raster files and other datasets produced by OpenET can be downloaded from the OpenET API (https://openet-api.org/), Google Earth Engine (https://developers.google.com/s/results/earth-engine/datasets?q=openet), or SGMA-OpenET-California | Powered by Box (https://cadwr.app.box.com/v/OpenET-California). 3. The agricultural land mask used to summarize is included below. Guidance: The original OpenET v2.1 30-meter ET data were created with units of mm, while the spatial averages are displayed on the SGMA data viewer are in depth units of inches and volume units of acre-feet. Blank cells indicate missing data or filtered errors. Users should be aware that the spatial coverage of ET values may vary month-to-month and that a supplemental data layer describes the percent coverage for each month of data to guide interpretation and use. The percent coverage layers could be found in the folder(cadwr-basin-summaries) on GitHub.
Feather River Watershed Monitoring Study
The Feather River watershed serves as a source of water for the State Water Project (SWP), one of the nation’s largest water conveyance projects. The California Department of Water Resources (DWR) owns and operates three reservoirs in the upper portion of this watershed: Antelope Lake, Frenchman Lake, and Lake Davis. Outflows from these reservoirs and runoff from the remainder of the watershed ultimately flow into Lake Oroville, another DWR reservoir. Water in these reservoirs is used as a source for drinking water supply, recreation, and for fish and wildlife beneficial uses. Historically, DWR’s water quality monitoring efforts in this watershed had been minimal due to relatively stable watershed conditions and minimal concerns affecting the SWP. In 2018, however, the Camp Fire resulted in a large burn upstream of Lake Oroville, raising concerns about water quality impacts from the post-fire runoff. In response, DWR initiated a short-term study to monitor runoff from this fire. Results from this study were provided in a [water quality assessment](https://data.cnra.ca.gov/dataset/lake-oroville-water-quality-assessment-for-the-2018-camp-fire). Following the end of that study, large wildfires again impacted the watershed above Lake Oroville. By the end of 2021, approximately 57 percent of the Lake Oroville watershed had burned in a three year period. Additionally, the 2021 Beckwourth Complex fire burned 90 percent of the Frenchman Lake watershed. In response to these fires, DWR initiated a broader post-fire water quality monitoring study. This study encompassed a larger geographic area, included more diverse sample locations, and included both burned and unburned portions of the watershed. The primary objectives of this new study were to assess the water quality of runoff and its impacts from inflow to SWP reservoirs, as well as, providing a larger baseline of water quality data for the watershed than had previously been available. The data provided as part of this study includes both these inflow samples and reservoir samples that were collected as part of DWR's [Routine Water Quality Monitoring Program](https://data.cnra.ca.gov/dataset/state-water-project-water-quality).

State Water Project Routine Water Quality Monitoring
The California State Water Project (SWP) is one of the nation’s largest water conveyance projects. Its geographic extent stretches from Sierra Nevada lakes north of Lake Tahoe, down the Central Valley, across several mountain ranges, and through the Mojave Desert, ultimately terminating at four large reservoirs in Southern California. The SWP also supplies water to communities in the northern and southern San Francisco Bay Area and along the Central Coast. In total, the SWP delivers raw drinking water to treatment plants serving over 27 million people, provides irrigation water for more than 750,000 acres of farmland, and supports recreational access at many lakes and reservoirs throughout the state. The Division of Operations and Maintenance within the Department of Water Resources (DWR) monitors water quality in the SWP at locations strategically situated throughout the Project. The SWP monitoring program began in the early 1960s and continues to this day. The location, frequency, and constituents tested for have changed several times during this period to meet the new and expanding needs of SWP water users. The bulk of samples collected for this monitoring effort have been analyzed by DWR’s internal laboratory, Bryte Lab. Additional tests outside of Bryte Lab’s capability or capacity have been analyzed at non-DWR affiliated laboratories. This dataset covers all samples collected as part of the SWP’s routine water quality monitoring program. This does not include data collected for special projects, specific permit or regulatory requirements, or short-term studies. The following sections provide more information about specific types and groups of samples and their data analysis and availability. ___Standard Water Quality Analytes:___ This group of data contains the most commonly sampled for analytes and parameters for this program. This includes anions, cations, nutrients, organic carbon, solids, and field measurements such as conductivity, pH, turbidity, and water temperature. These data are analyzed by Bryte Lab and are available on the [Water Data Library](https://wdl.water.ca.gov/waterdatalibrary/). ___Asbestos:___ Samples for asbestos analysis have been collected at a few locations within the SWP since 1980 following detections of asbestos fibers in water delivered from the SWP. Subsequent studies showed several point and non-point sources that may contribute to asbestos in the SWP. The ongoing samples have been analyzed at several different labs during this time. Data from before 2009 have not been compiled into CSV format but are available as laboratory reports. These reports can be obtained by submitting a [record request](https://californiadwr.mycusthelp.com/WEBAPP/_rs/(S(3q2tw3v2guzqsnh1objifgtv))/supporthome.aspx). Data from 2009 and after are available in CSV format in this dataset with the exception of data during 2011-2014 when several reports were lost. ___Organic Chemicals:___ Several different classes of organic chemicals have been a part of the SWP monitoring program for many decades including analysis of phenols from the start of the program. Continued analysis of organic chemicals has included various types of pesticides, herbicides, semi-volatile organic compounds, and volatile organic compounds. The specific list of compounds has changed over time to meet specific program needs and laboratory analytical capabilities. Samples before 2020 were analyzed by Bryte Lab and are available on the [Water Data Library](https://wdl.water.ca.gov/waterdatalibrary/). Samples in 2020 and after were sent to non-DWR affiliated labs and are available in this dataset. ___PFAS:___ Sampling for PFAS in the SWP began in 2020 and has grown in frequency and number of sampling sites. These samples have been analyzed at non-DWR affiliated labs and are available in this dataset. ___Radionuclides:___ Samples for gross alpha, gross beta, Potassium-40, and tritium have been collected since the late 1990s. These samples have been analyzed by the California Department of Public Health’s Drinking Water and Radiation Laboratory. Results prior to 2010 have not been compiled into CSV format but are available as laboratory reports. These reports can be obtained by submitting a [record request](https://californiadwr.mycusthelp.com/WEBAPP/_rs/(S(3q2tw3v2guzqsnh1objifgtv))/supporthome.aspx). Data from 2010 and after are available in CSV format in this dataset. Suggested Citation: State Water Project Water Quality Program. (n.d.). Routine Water Quality Data.

California School District Areas 2025-26
This layer serves as the authoritative geographic data source for all school district area boundaries in California. School districts are single purpose governmental units that operate schools and provide public educational services to residents within geographically defined areas. Agencies considered school districts that do not use geographically defined service areas to determine enrollment are excluded from this data set. In order to view districts represented as point locations, please see the "California School District Offices" layer. The school districts in this layer are enriched with additional district-level attribute information from the California Department of Education's data collections. These data elements add meaningful statistical and descriptive information that can be visualized and analyzed on a map and used to advance education research or inform decision making. School districts are categorized as either elementary (primary), high (secondary) or unified based on the general grade range of the schools operated by the district. Elementary school districts provide education to the lower grade/age levels and the high school districts provide education to the upper grade/age levels while unified school districts provide education to all grade/age levels in their service areas. Boundaries for the elementary, high and unified school district layers are combined into a single file. The resulting composite layer includes areas of overlapping boundaries since elementary and high school districts each serve a different grade range of students within the same territory. The 'DistrictType' field can be used to filter and display districts separately by type. Boundary lines are maintained by the California Department of Education (CDE) and are effective in the 2025-26 academic year . The CDE works collaboratively with the US Census Bureau to update and maintain boundary information as part of the federal School District Review Program (SDRP). The Census Bureau uses these school district boundaries to develop annual estimates of children in poverty to help the U.S. Department of Education determine the annual allocation of Title I funding to states and school districts. The National Center for Education Statistics (NCES) also uses the school district boundaries to develop a broad collection of district-level demographic estimates from the Census Bureau’s American Community Survey (ACS). The school district enrollment and demographic information are based on student enrollment counts collected on Fall Census Day (first Wednesday in October) in the 2025-26 academic year. These data elements are collected by the CDE through the California Longitudinal Achievement System (CALPADS) and can be accessed as publicly downloadable files from the Data & Statistics web page on the CDE website https://www.cde.ca.gov/ds.
This dataset is available for download from: Parcelization (File Geodatabase) Parcelization, a measure of size and density of parcels in a localized area, is a development feasibility factor that is used in evaluating substations’ ability to support new utility-scale resources in long-term energy planning. A statewide dataset of parcel boundaries are used to develop this index. The parcels are converted into a 90-meter raster, containing values of a unique identifier reflective of Parcel APN. A focal statistics tool is used to count the number of unique parcels within a 0.5 mile radius of each parcel. This output is provided here and is an intermediate output to the final parcelization map. Users who wish to use this information to produce the final map should overlay parcel boundary data and extract the mean raster value within each parcel. The map is limited to the area considered with solar technical resource potential after a minimum set of land-use screens (referred to as the Base Exclusions) has been applied. More information on the methods developing this dataset as well as the main use of this dataset in state electric system planning processes can be found in a recent CEC staff report and workshops supporting the resource-to-busbar mapping methodology for the 2024-2025 Transmission Planning Process.

Calfornia Department of Forestry and Fire Protection
(Webpage Under Development) The Department of Water Resources (DWR) provides Technical Support Services (TSS) to assist Groundwater Sustainability Agencies (GSAs) with the implementation of their Groundwater Sustainability Plans (GSPs) and other local entities to better understand groundwater conditions. These services support data collection, groundwater monitoring, and improved understanding of groundwater conditions to help advance sustainable groundwater management efforts across California. Through the TSS program, DWR has partnered with GSAs and other entities on projects across the state to drill and construct groundwater monitoring wells, install groundwater level recording and telemetry equipment, perform downhole camera and geophysical surveys, and collect and analyze groundwater for general chemistry. The data and reports generated from these efforts are publicly available to support ongoing groundwater management and planning. Additional information can be found on the [Assistance and Engagement webpage](https://water.ca.gov/Programs/Groundwater-Management/Assistance-and-Engagement "Assistance and Engagement webpage"). #Summary of Completed TSS Projects To date, DWR has completed TSS projects in **35 groundwater subbasins**, constructing **234 monitoring wells** at **92 sites** statewide. Each of these wells have been assigned a State Well Number (SWN), have had a Well Completion Report (WCR) submitted to DWRs Online System for Well Completion Reports (OSWCR), and have been registered either through the California Statewide Groundwater Elevation Monitoring (CASGEM) Online System or the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM). Groundwater level data from these wells are collected by the GSA or DWR and submitted to CASGEM and/or the MNM. These data can be viewed on the [Water Data Library (WDL)](https://wdl.water.ca.gov/waterdatalibrary/ "Water Data Library (WDL)"). WCRs for these wells can be found using the [Well Completion Report Map Application](https://dwr.maps.arcgis.com/apps/webappviewer/index.html?id=181078580a214c0986e2da28f8623b37 "Well Completion Report Map Application"). A summary table of completed TSS wells including their associated well name(s), site code(s), SWN(s), and WCR number(s), can be viewed and/or downloaded here: [DWR Completed TSS Wells](https://data.cnra.ca.gov/dataset/completed-tss-wells/resource/5263a74b-aae2-4040-9e69-7bf85b9ff120) An interactive GIS map containing a feature set of all completed TSS wells can be accessed here: [GIS Map of Completed TSS Wells](https://www.arcgis.com/apps/mapviewer/index.html?url=https://services.arcgis.com/aa38u6OgfNoCkTJ6/ArcGIS/rest/services/DWR_Technical_Support_Services_(TSS)_Wells/FeatureServer&source=sd “GIS Map of Completed TSS Wells”) The individual TSS well locations, associated borehole lithologic information, and groundwater level data can be viewed on the [SGMA Data Viewer](https://sgma.water.ca.gov/webgis/?appid=SGMADataViewer#gwlevels “SGMA Data Viewer”) by: 1.

Preliminary SB 535 Disadvantaged Communities Designation 2026
CalEPA issued previous Disadvantaged Communities (DAC) designations in 2014, 2017, and 2022. The 2026 DAC designation builds on lessons learned from previous designations, utilizes the latest and best available data, and considers factors related to data unavailability. CalEPA is proposing to define communities in terms of census tracts and include the following in the 2026 DAC designation: - Census tracts with the highest 25 percent of CalEnviroScreen 5.0 overall scores. - Census tracts with the highest 5 percent of CalEnviroScreen 5.0 pollution burden scores. - Census tracts that overlap at least 25 percent with a 2022 DAC-designated census tract based on CalEnviroScreen 4.0. - Lands under the control of federally recognized tribes, with updated tribal boundaries data.

Surface Water - Chemistry Results - CEDEN Augmentation
This dataset includes field and lab chemistry data that has been submitted to the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN), but has not been loaded into the CEDEN database. It is a subset of the chemistry data that has been submitted to CEDEN since approximately December 2020, and supplements the data found in the main [Surface Water - Chemistry Results](https://data.ca.gov/dataset/surface-water-chemistry-results) dataset. Note that the data in this dataset is now included in the [CEDEN Query Tool](https://ceden.waterboards.ca.gov/CQT/Home/AqtTool). For consistency, many of the conditions applied to the other CEDEN data found on this portal are also applied to this supplemental dataset (e.g., no rejected data or replicates are included). However, this supplemental data is provisional and may not reflect all of the QA/QC controls applied to the regular CEDEN data. This dataset also contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result (like the main [Surface Water - Chemistry Results](https://data.ca.gov/dataset/surface-water-chemistry-results) dataset referenced above).
California State Income Limits reflect updated median income and household income levels for acutely low-, extremely low-, very low-, low- and moderate-income households for California’s 58 counties (required by Health and Safety Code Section 50093). These income limits apply to State and local affordable housing programs statutorily linked to HUD income limits and differ from income limits applicable to other specific federal, State, or local programs.

CA SalesandUseTaxRates 2017toPresent Public
Each annual set of sales and use tax rate polygons includes data for all four quarters, except for the years 2018 and 2019 as noted in the metadata for those years. The DateStamp field is the first day of the quarter in which the sales tax rate was effective. Mapping standards for coastline and redevelopment areas have evolved over time. (Redevelopment areas can be identified in the data by searching on a TAC_txt code that does not end in ‘0000’.) Most changes stem from city annexations or detachments; others come from boundary corrections. For details, see the BOE_CityCounty boundaries and BOE_CityAnx GIS datasets.

The Behavioral Health Public County Profile represents DHCS’s effort to consolidate key county behavioral health information into a consistent and accessible format, helping reduce fragmented data sources and improve transparency. This marks a significant step forward in modernizing and streamlining access to behavioral health data. The initial version of the Behavioral Health Public County Profile provides a high-level snapshot of key information, including –draft Integrated Plan status, county demographics, and homelessness and housing visualizations, as well as a quick reference guide within the display for the public to better understand the information being presented. Using standardized definitions and shared identifiers, the Behavioral Health Public County Profile data is comparable between counties and statewide and will be aligned in public reporting. The Behavioral Health Public County Profile visualizations will be continuously updated as new data sets and behavioral health reporting becomes available. DHCS is releasing the Behavioral Health County Profile in phases based on data availability and reporting timelines. The initial version includes the following sections: * Overview * Demographics (general population and Medi-Cal behavioral health) * Integrated Plan (draft submission status) * Homeless/Housing * Performance (COMING SOON) * BH Reporting (COMING SOON) The Behavioral Health County Profile makes county behavioral health data comparable statewide and provides aligned public reporting. It provides a digestible snapshot of Integrated Plans, funding information, compliance status, and performance over time—and will be enhanced with additional data sets so DHCS and counties can work from the same facts at the same time. This marks an important step forward in behavioral health data access just two years after California voters passed the Behavioral Health Services Act (BHSA).
Cropland Index The Cropland Index evaluates lands used to produce crops based on the following input datasets: Revised Storie Index, California Important Farmland data, Electrical Conductivity (EC), and Sodium Adsorption Ratio (SAR). Together, these input layers were used in a suitability model to generate this raster. High values are associated with better Croplands California Important Farmland data – statistical data used for analyzing impacts on California’s agricultural resources from the Farmland Mapping and Monitoring Program. Agricultural land is rated according to soil quality and irrigation status. The maps are updated every two years (on even numbered years) with the use of a computer mapping system, aerial imagery, public review, and field reconnaissance. Cropland Index Mask - This is a constructed data set used to define the model domain. Its footprint is defined by combining the extent of the California Important Farmland data (2018) classifications listed above and the area defined by California Statewide Crop Mapping for the state of California. Prime Farmland – farmland with the best combination of physical and chemical features able to sustain long term agricultural production. This land has the soil quality, growing season, and moisture supply needed to produce sustained high yields. Land must have been used for irrigated agricultural production at some time during the four years prior to the mapping date. Farmland of Statewide Importance – farmland similar to Prime Farmland but with minor shortcomings, such as greater slopes or less ability to store soil moisture. Land must have been used for irrigated agricultural production at some time during the four years prior to the mapping date. Unique Farmland – farmland of lesser quality soils used for the production of the state’s leading agricultural crops. This land is usually irrigated but may include Non irrigated orchards or vineyards as found in some climatic zones in California. Land must have been cropped at some time during the four years prior to the mapping date. Gridded Soil Survey Geographic Database (gSSURGO) – a database containing information about soil as collected by the National Cooperative Soil Survey over the course of a century. The information can be displayed in tables or as maps and is available for most areas in the United States and the Territories, Commonwealths, and Island Nations served by the USDA-NRCS. The information was gathered by walking over the land and observing the soil. Many soil samples were analyzed in laboratories. California Revised Storie Index - is a soil rating based on soil properties that govern a soil’s potential for cultivated agriculture in California. The Revised Storie Index assesses the productivity of a soil from the following four characteristics: Factor A, degree of soil profile development; factor B, texture of the surface layer; factor C, slope; and factor X, manageable features, including drainage, microrelief, fertility, acidity, erosion, and salt content. A score ranging from 0 to 100 percent is determined for each factor, and the scores are then multiplied together to derive an index rating. Electrical Conductivity - is the electrolytic conductivity of an extract from saturated soil paste, expressed as Deci siemens per meter at 25 degrees C. Electrical conductivity is a measure of the concentration of water-soluble salts in soils. It is used to indicate saline soils. High concentrations of neutral salts, such as sodium chloride and sodium sulfate, may interfere with the adsorption of water by plants because the osmotic pressure in the soil solution is nearly as high as or higher than that in the plant cells. Sodium Adsorption Ratio - is a measure of the amount of sodium (Na) relative to calcium (Ca) and magnesium (Mg) in the water extract from saturated soil paste. It is the ratio of the Na concentration divided by the square root of one-half of the Ca + Mg concentration. Soils that have SAR values of 13 or more may be characterized by an increased dispersion of organic matter and clay particles, reduced saturated hydraulic conductivity (Ksat) and aeration, and a general degradation of soil structure.

Seismic Compliance Data By County for General Acute Care Hospitals
Data for seismic compliance in general acute care hospitals is grouped by counties. All general acute care hospital buildings are assigned a Structural Performance Category (SPC) which measures the probable seismic performance of building structural systems. Building structural systems include beams, columns, shear walls, slabs, and foundations. SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. State law requires all SPC 1 buildings to be removed from providing general acute care services by January 1, 2020, unless an approved extension has been granted, and all SPC 2 buildings to be removed from providing general acute care services by January 1, 2030. A hospital facility meets the January 1, 2030 requirements if all the general acute care buildings on campus are SPC and NPC compliant. 2030 compliant SPC ratings are either SPC 3, 4, 4D, or 5. 2030 compliant NPC ratings is NPC 5. Data is provided for both hospital facilities and hospital buildings. Data is updated approximately every two weeks.

Dry Domestic Well Susceptibility (Technical Notes)
DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the [Dry Domestic Well Susceptibility within Groundwater Basins Dashboard](https://storymaps.arcgis.com/stories/f2b252d15a0d4e49887ba94ac17cc4bb#ref-n-aoS5Sy) (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation. __If you are currently experiencing a dry domestic well, you can report that to DWR’s [Dry Well Reporting System](www.mydrywell.ca.gov) which will connect you with available local assistance.__ The query for domestic wells was based on DWR’s Online System for Well Completion Reports (OSWCR). Well uses that are specified on well completion reports have been grouped into domestic wells (See attribute 'B118WellUse'). The complete Well Completion Report Dataset is available at https://data.cnra.ca.gov/dataset/well-completion-reports. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development as part of ongoing enhancements to CalGW Live. Once the format is finalized, the service will be hosted at https://gis.water.ca.gov/arcgis/rest/services/. _DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data._ _This dashboard and the underlying analysis provide a density map of domestic wells that are susceptible to going dry if recent groundwater trends continue. The map can be used to evaluate the relative density distribution within groundwater basins. However, the map should not be used to estimate the absolute number of domestic wells that are susceptible to going dry for any area or groundwater level scenario. While the applied groundwater level scenario is based on best available datasets, the scenario is hypothetical, and is chosen to resolve regional differences in the density of domestic wells that are susceptible to going dry. Available groundwater level data are interpolated and projected to domestic wells locations. To achieve near statewide coverage for this analysis, groundwater level measurements are projected up to 10 miles in areas where no local monitoring exists. Filling these groundwater level data gaps with new monitoring stations will improve the reliability of the Dry Well Susceptibility Analysis. The applied model for the depth at which a domestic well is susceptible to going dry is simplified and uncalibrated and is not intended to represent any specific well failure mode. Future calibration of this model, and consideration of well construction details will improve the reliability of the Dry Well Susceptibility Analysis._

Domestic and Irrigation Wells (GIS Feature Service)
Information for domestic and irrigation wells are based on DWR’s Online System for Well Completion Reports (OSWCR). The complete Well Completion Report Dataset is available at https://data.cnra.ca.gov/dataset/well-completion-reports. WCRs are spatially referenced with the Public Land Survey System square-mile sections, listed as meridian, township, range, and section in the “MTRS” field. While many wells now include exact coordinates, the majority in the dataset are still derived from the centroid of the section. This service follows the Bulletin 118 Update 2025 categorization of well use. The “B118WELLUSE” column aggregates all “PLANNEDUSEFORMERUSE” categories of the OSWCR dataset into six well types: domestic, irrigation, industrial, monitoring, public supply, and other. For example, a WCR well with an “other domestic” type would become a “domestic” type. The __Domestic Wells Dashboard__ is available at https://storymaps.arcgis.com/stories/f2b252d15a0d4e49887ba94ac17cc4bb#ref-n-CQHVif The __Irrigation Wells Dashboard__ is available at https://storymaps.arcgis.com/stories/f2b252d15a0d4e49887ba94ac17cc4bb#ref-n-v3v7cy The OSWCR database is the best statewide data available to review and estimate the quantities, ages, distributions, depths, and types of installed wells. Known limitations of the dataset include the following: * Despite statutory requirements, WCRs may not have been submitted to DWR within the required 60 days, or at all, for constructed, altered, abandoned, or destroyed wells. This is also the case for wells constructed prior to the statutory requirements for WCR submittal. This may cause an under-reporting of wells in the state. * WCRs do not indicate whether a well is currently active and well owners are not required to report a well status to DWR. OSWCR tracks WCRs, not the active or inactive status of the well. WCRs for the destruction of wells are not paired to the original WCRs for the construction of those same wells. * WCRs may include errors in the reported well locations. On some WCRs, the location information may be missing. * WCRs may have inaccurate or incomplete well construction information. * WCRs may not provide the date of installation (“DATEWORKENDED” field in dataset) or well use classification (“PLANNEDUSEFORMERUSE” field in dataset). DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.

Dry Domestic Well Susceptibility and Reporting Fact Sheet
This resource includes a brief fact sheet describing DWR's [Dry Domestic Well Susceptibility Analysis](https://data.cnra.ca.gov/dataset/calgw-live/resource/e0bf3d2b-ceca-41ca-876f-d3e378503583) and [Dry Well Reporting System](https://mydrywell.water.ca.gov). DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the Dry Domestic Well Susceptibility within Groundwater Basins Dashboard (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation.
EA_02_01 -- Identification Numbering for Water Quality Monitoring Sites
The Division of Operations and Maintenance uses an alphanumeric code to identify water quality sampling sites on the State Water Project. Each code has a two to three letter prefix, which identifies the area or region of the SWP where the site is located. The list of these prefixes and their associated area are listed in this document. A prefix from this list can be entered into the "Station Number" field of the WDL Station & County search window to find all sampling sites in that area.
Local governments are required to inform HCD about any local tenant preference ordinance the local government maintains when the jurisdiction submits their annual progress report on housing approvals and production, per Government Code 7061 (SB 649, 2022, Cortese). Effective January 1, 2023, local governments adopting a tenant preference are required to create a webpage on their internet website containing authorizing local ordinance and supporting materials, no more than 90 days after the ordinance becomes operational.

Seasonal Groundwater Level Changes 1, 3, 5 and 10-Year (GIS Feature Service)
Seasonal groundwater level reports provide information from selected water level measurements and are intended to portray the change in seasonal groundwater levels over specific time intervals. Each point shows the calculated difference between the measured groundwater levels from the selected time periods. The change in groundwater level is plotted on the map only if a measurement exists in both time periods at a well. These change values are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. Data from the Periodic Groundwater Levels dataset is queried and categorized into seasons for each year, where "Spring" includes measurements occurring January through May, and "Fall" includes measurements occurring September through November. Measurements are excluded if they had quality codes indicating active pumping or flowing conditions, oil or foreign substances, or other quality issues. Of the Spring measurements for each well, the maximum groundwater level is taken to represent the seasonal high groundwater level (i.e. the minimum depth to water). For Fall, the minimum groundwater level measurement for each well is taken to represent the seasonal low groundwater level (i.e. the maximum depth to water). For Spring, the differences between the recent Spring maximum and the past Spring maximums (1, 3, 5, or 10 years ago) are shown in the WSE_CHANGE field. For Fall, the difference between the recent Fall minimum and the past Fall minimums are shown in the WSE_CHANGE field. The data is then classified into five categories in the WSE_CHANGE_CATEGORY field: decrease more than 25ft, decrease 5-25ft, no significant change (-5ft and +5ft), increase 5-25ft, increase more than 25ft. The __Seasonal Groundwater Level Changes Dashboard__ is available at https://storymaps.arcgis.com/stories/b3886b33b49c4fa8adf2ae8bdd8f16c3#ref-n-feNqfG DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.

Neither the Department nor any of the data sources, datasets, or maps shall be responsible for any errors or omissions, or for the use or results obtained from using this information. A Groundwater Sustainability Agency is not required to use this Process Document, and its use does not guarantee the adequacy of a Groundwater Sustainability Plan that relies on such analytical processes.
Current Groundwater Level Statistics (GIS Feature Service)
The DWR Groundwater Level Percentile Statistics are based on the USGS Groundwater Watch concept of comparing the most recent groundwater level measurement to historical measurements for the same month. For a well to be ranked, the most recent measurement must have occurred within the last 18 months, and measurements from at least 10 years must exist for that month. These statistics are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. This dataset is maintained primarily in the DWR Enterprise Water Management database. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. Groundwater level percentile class information is determined by comparing a single measurement to all other measurements collected in the same month at that well. The “percentile class” is a statistical determination that describes the percentage of all measurements that are below a specific measurement. If 90 percent of measurements are below (deeper) than a given measurement, then it is in the 90th percentile and if only 10 percent of measurements are below, then that measurement is in the 10th percentile. An average measurement is the 50th percentile. The measurement is classified into one of eight percentile categories, or statistical bins, based on all measurements for that well. These categories are: Lowest on Record, lowest 10% (Much Below Normal), 10-25% (Below Normal), 25-50% (Normal), 50-75% (Normal), 75-90% (Above Normal), highest 90% (Much Above Normal), and Highest on Record. The __Current Groundwater Level Conditions Dashboard__ is available at https://storymaps.arcgis.com/stories/b3886b33b49c4fa8adf2ae8bdd8f16c3#ref-n-uWnp7G DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.
Well Perforation data is not available for all wells in this dataset. Well perforations are screened intervals (openings) allowing groundwater to enter well casing. Wells can have multiple screen intervals, up to 10 screened intervals can be recorded for each well in this dataset.

Data Dictionary - Seismic compliance data by county for general acute care hospitals
Data for seismic compliance in general acute care hospitals is grouped by counties. All general acute care hospital buildings are assigned a structural performance category (SPC). SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. State law requires all SPC 1 buildings to be removed from providing general acute care services by 2020 and all SPC 2 buildings to be removed from providing general acute care services by 2030. Therefore, a hospital facility that may be comprised of a number of hospital buildings meets the 2020 requirements if there are no SPC 1 buildings on campus. A hospital facility meets the 2030 requirements if all the buildings on campus are either SPC 3, 4 or 5. Data is provided for both hospital facilities and hospital buildings. Data is updated approximately every two weeks.

Current Groundwater Levels (GIS Feature Service)
This service includes points representing monitoring wells in DWR's groundwater elevation database which have a groundwater elevation measurement reported in the last 18 months. Information on the most recent measurement is included. This information is based on the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Monitoring at active sites is typically done manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. The field LAST_GSE_GWE represents the depth to groundwater and is calculated by subtracting the groundwater elevation (LAST_GWE) from the ground surface elevation (LAST_WLM_GSE). The Depth to Groundwater is then categorized into five bins for symbolization on the Current Groundwater Levels Dashboard. Those bins and their labels are: 0 ft through 25 ft (denoted as "25" in the attribute table), greater than 25 ft through 100 ft ("100"), greater than 100 ft through 200 ft ("200"), greater than 200 ft through 500 ft ("500"), and greater than 500 ft ("9999").

Dry Domestic Well Susceptibility (GIS Feature Service)
DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the [Dry Domestic Well Susceptibility within Groundwater Basins Dashboard](https://storymaps.arcgis.com/stories/f2b252d15a0d4e49887ba94ac17cc4bb#ref-n-aoS5Sy) (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation. __If you are currently experiencing a dry domestic well, you can report that to DWR’s [Dry Well Reporting System](www.mydrywell.ca.gov) which will connect you with available local assistance.__ The query for domestic wells was based on DWR’s Online System for Well Completion Reports (OSWCR). Well uses that are specified on well completion reports have been grouped into domestic wells (See attribute 'B118WellUse'). The complete Well Completion Report Dataset is available at https://data.cnra.ca.gov/dataset/well-completion-reports. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development as part of ongoing enhancements to CalGW Live. _DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data._ _This dashboard and the underlying analysis provide a density map of domestic wells that are susceptible to going dry if recent groundwater trends continue. The map can be used to evaluate the relative density distribution within groundwater basins. However, the map should not be used to estimate the absolute number of domestic wells that are susceptible to going dry for any area or groundwater level scenario. While the applied groundwater level scenario is based on best available datasets, the scenario is hypothetical, and is chosen to resolve regional differences in the density of domestic wells that are susceptible to going dry. Available groundwater level data are interpolated and projected to domestic wells locations. To achieve near statewide coverage for this analysis, groundwater level measurements are projected up to 10 miles in areas where no local monitoring exists. Filling these groundwater level data gaps with new monitoring stations will improve the reliability of the Dry Well Susceptibility Analysis. The applied model for the depth at which a domestic well is susceptible to going dry is simplified and uncalibrated and is not intended to represent any specific well failure mode. Future calibration of this model, and consideration of well construction details will improve the reliability of the Dry Well Susceptibility Analysis._

20-Year Groundwater Level Trends (GIS Feature Service)
Groundwater levels at selected wells were analyzed using the Mann-Kendall non-parametric test to determine whether a statistically significant trend (declining trend, no trend, or increasing trends in groundwater levels) was present during the specified time period. These trends are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements To ensure sufficient data quality and temporal coverage, each well included in the analysis must meet minimum data requirements: at least 10 unique years of spring measurements, and those spring measurements must span at least 15 years within the 20-year period. These spring measurements are defined as the highest groundwater level observed between January 1 and May 31 of each year to minimize seasonal effects. When more than one spring measurement was available for a year, the highest (shallowest) water level was selected to represent that year. If a statistically significant trend was observed, the Thiel-Sen method was used to calculate the estimated slope of the trend line to quantify the decline or increase. Statistical trends were calculated using the Mann-Kendall trend test and the Thiel-Sen slope estimator, implemented via the "original_test" function in the pymannkendall Python library. The seasonal test was not applied because the data were already limited to spring measurements. By default, the Mann-Kendall function calculates slope based on the number of unique measurement years. However, to better reflect true long-term change, the slope was normalized to account for the actual time span between the first and last measurements using the formula: normalized_slope = slope × (count – 1) / (last year – first year), where count is the number of unique measurement years. The normalized slope is listed in the field “norm_slope”. The data is categorized into five bins for symbolization on the 20-Year Trends Dashboard. These bins are represented in the fields “SlpSplits”, “SlpSplit”, and “SortOrder”. “SlpSplits” is a label describing the bin, while “SortOrder” is a corresponding code to represent the bin. The “SortOrder” is combined with the “SlpSplits” label in the “SlpSplit” field. The five bins and their sorting codes are: increasing trend of greater than 2.5 feet/year (“1”), increasing trend of up to 2.5 feet/year (“2”), no trend (“3”), decreasing trend of down to 2.5 feet/year (“4”), and decreasing trend of greater than 2.5 feet/year (“5”). The “trend” field denotes whether a well displays an increasing trend, decreasing trend, or no trend. If no trend is observed, “SlpSplits” is set to “No trend”. If there is an increasing or decreasing trend, the value in “norm_slope” is categorized as being either greater or less than 2.5 feet/year in magnitude. The __20-year Trends Dashboard__ is available at https://storymaps.arcgis.com/stories/b3886b33b49c4fa8adf2ae8bdd8f16c3#ref-n-jO4tjj DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data.
