Attributed California Water Supply Well Completion Report Data for Selected Areas, Derived from CA WCR OSCWR Data

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-12T00:00:00Z
This Well Completion Report geospatial dataset represents an index to a subset of records available from the California Department of Water Resources' (DWR) Online System for Well Completion Reports (OSWCR). This release contains water supply well records from Amador, Calaveras, El Dorado, Nevada, Placer, Sacramento, San Bernardino, Sutter, and Yuba counties. The USGS California Water Science Center GAMA project has provided additional attributes: top of open interval; number of open intervals; and various other identifiers such as public supply well number and USGS site number where they can be identified. In some cases, locations are georeferenced to finer resolution based on county APN or 911 geospatial datasets. The attributed information is linked to the redacted publicly available image when the link can be resolved. This dataset is for information purposes only. All attribute values should be verified by reviewing the original Well Completion Report. California Water Code Section 13752 allows for the release of redacted copies of well completion reports to the public. DWR is the authoritative source of these data. https://data.ca.gov/dataset/well-completion-reports
