Groundwater Level Monitoring

Groundwater Levels

The Southern District maintains a computer database with about 1.9 million groundwater level measurements taken in more than 23,000 wells by District personnel or personnel from other agencies. Some of these measurements date back to 1900. The District also has microfiche with statewide groundwater level measurements taken prior to about 1985. These data are orgainized by State Well Number.

The Department of Water Resources makes groundwater level data available on line for much of California. Currently, selected groundwater level data are available for most counties in the Southern District. These data are provided by the Orange County Water District, Ventura County Public Works Agency, and U.S. Geological Survey.
