Outreach to Rural Well Owners Underway
Approximately 9,500 rural well owners in Sonoma County received surveys designed to elicit their concerns and ideas about local groundwater conditions. The purpose of the survey was to raise awareness about local groundwater management and to solicit feedback from well owners regarding any concerns they may have about groundwater in the basin. The survey results were used as the basis for focus groups to provide an opportunity for more in-depth discussions of issues and ideas for improving groundwater conditions.
This joint project of the county’s three Groundwater Sustainability Agencies (GSAs) was the first step in an engagement project designed to educate and receive feedback from well owners in the Petaluma Valley, Santa Rosa Plain and Sonoma Valley groundwater basins.
Practitioners Work Groups
The three Sonoma County GSAs received funding from California Department of Water Resources through the California Drought, Water, Parks, Climate, Coastal Protection, and Outdoor Access for All Act of 2018 (Proposition 68) to facilitate four work groups comprised of technical subject experts. The work groups were formed to help with the development of the Groundwater Sustainability Plans in four areas:
- Rural residential population projections;
- Agricultural water demand projections;
- Groundwater-dependent ecosystems; and
- Interconnected surface water depletion.
The work groups began meeting in summer 2020 and were facilitated by a neutral facilitator from the Consensus and Collaboration Program with CSU Sacramento. The work group products were shared with the Board and Advisory Committees of the GSAs, and used to develop the water budgets and Sustainable Management Criteria for Interconnected Surface Water.

Community Workshop on Sustainable Groundwater in Our Basin
Do you get your water from a well? Do you worry about your water quality or water levels? Are you concerned about the costs of water in the future?
This public workshop was held on July 15, 2020.
