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 is 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 will be used as the basis for focus groups that will 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) is 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 the GSAs anticipate that all work will be complete in February 2021. The meetings are 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 will be used to develop the water budgets and Sustainable Management Criteria for Interconnected Surface Water.

Meeting materials are below:

Climate Change Workshop

On May 22, the three Groundwater Sustainability Agencies held a public workshop “How a changing climate could affect our groundwater basins – and what we’re doing about it.” The focus of this public workshop was on how climate change must be addressed in the Groundwater Sustainability Plans.
