Adelaida Hydrogeologic Study

The Upper Salinas - Las Tablas RCD is partnering with the County of San Luis Obispo and U.S. Geological Survey to respond to recent concerns regarding groundwater conditions in the Adelaida area west of Paso Robles.  The goal of the study is to work collaboratively with local landowners to get feedback on historical and current groundwater conditions, provide informative data, and help guide efforts to assess and analyze the hydrogeology of the Adelaida area.

USGS is currently conducting groundwater measurements within the study area.  If you are interested in providing data for Task 2 of the study, please contact
