In partnership with the Sonoma County Water Agency, the Gold Ridge RCD is recruiting landowners with private wells to participate in a voluntary groundwater elevation monitoring program. The project covers the Wilson Grove and Bodega Bay groundwater basins, shown on the adjacent map.

The goal of the program is to assess seasonal and long-term trends in groundwater levels as part of the statewide CASGEM program.

Participation in the program is entirely voluntary and confidential. If you are interested in having your well included in the groundwater elevation monitoring network, please contact:
Noelle Johnson
(707) 823-5244

Or download the statement of interest to fill out and return to the RCD.
