Select Borehole Data for the Salton Sea area and vicinity, Imperial-Riverside-San Diego-San Bernardino Counties, CA

Borehole lithology data from drillers' log descriptions were compiled for the Salton Sea area and vicinity. This data will be utilized to support hydrogeologic and hydrologic investigations. Data for some parts of the Salton Sea Watershed were already compiled for other USGS reports. These included Borrego Valley (Faunt and others, 2015), and the East Mesa (Shepherd and Rosenberg, 2024). For the parts of the watershed that were not already covered by a USGS report, wells were sourced from the California Department of Water Resources Online Well Completion Reports (California Department of Water Resources, 2024), a consultant report on in-sea geotechnical wells (URS, 2004), the California Natural Resources Agency DWR Airborne Electromagnetic (AEM) survey area 11 (California Natural Resources Agency, 2024), and California Department of Conservation Geological Energy Management Division (California Department of Conservation, 2024).
