California's Groundwater Live: Well Infrastructure

Hundreds of thousands of water wells have been drilled in California over the decades. This story map provides the latest information on water wells in California based on the submittals of well completion reports (WCRs) to DWR's Online System for Well Completion Reports (OSWCR), data from the State Water Resource Control Board's Division of Drinking Water, and data from the Household Water Supply Shortage Reporting System. The data shown below is updated weekly and shows the locations and well details for domestic, irrigation, and public supply wells. For a glossary of water terms used on this site click  here .

The following dashboards are not intended to address water quality. For further information about this topic, please refer to the  State Water Resources Control Board's Groundwater Ambient Monitoring and Assessment Program (GAMA).  

Domestic wells provide water to millions of Californians every day. Below is a dashboard designed to allow users to explore domestic wells throughout California based on well completion report information from DWR's  Online System for Well Completion Reports  (OSWCR). This dashboard allows a user to explore well information by county, groundwater basin, or hydrologic region as well as chronologically, by choosing to view wells installed over a specific time period. Users may also enter a street address to view wells in their area of interest. Each well record shown on the interactive maps represents an actual WCR which the user can view by clicking on the point of interest and selecting the hyperlink included in the well details pane.

Additional information about this dataset and how to download it to your computer can be found on the  California Natural Resources Open Data Platform .

Irrigation wells provide water to support California's booming agricultural industry each day. Below is a dashboard designed to allow users to explore irrigation wells throughout California based on well completion report information from DWR's  Online System for Well Completion Reports  (OSWCR). This dashboard allows a user to explore well information by county, groundwater basin, or hydrologic region as well as chronologically, by choosing to view wells installed over a specific time period. Users may also enter a street address to view wells in their area of interest. Each well record shown on the interactive maps represents an actual WCR which the user can view by clicking on the point of interest and selecting the hyperlink included in the well details pane.

Public supply wells provide water to tens of millions of Californians each day. Below is a dashboard designed to allow users to explore public supply wells throughout California based on wells regulated by the California State Water Resources Control Board's  Division of Drinking Water (DDW)  Program. This dashboard allows a user to explore well information by county, groundwater basin, or hydrologic region as well as by public water system type. Users may also enter a street address to view wells in their area of interest.

Reported dry wells in California are based on the Household Water Supply Shortage Reporting System. The Household Water Supply Shortage Reporting System is available online at at  https://mydrywatersupply.water.ca.gov/report/ .

DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard that contains information about dry domestic well susceptibility within groundwater basins in California. The map displays susceptibility per square mile based on analysis by combining the latest information on domestic well locations, depths, and local groundwater level conditions. The dashboard includes a map and information pane, along with various filtering options. Square miles are displayed on the map categorized by the density of domestic wells susceptible to going dry with gray representing wells not susceptible, tan representing low density of susceptible wells and purple representing a high density of susceptible wells. For additional information about this project and dry well reporting, please read the DWR's  Fact Sheet . For futher information about the analysis including how to download the dataset, please visit the  California Natural Resources Open Data Platform .
