Water Resources

​​The Sacramento County Groundwater Sustainability Agency (GSA) (a joint effort of the County of Sacramento Department of Water Resources and the Sacramento County Water Agency) will be considering new groundwater sustainability fees in our GSA areas of the Solano Subbasin and Cosumnes Subbasin. These fees will fund important groundwater sustainability work including monitoring groundwater conditions, complying with state regulations, and implementing groundwater sustainability programs.

​In 2021, ​the Cosumnes Subbasin, the Sacramento County GSA adopted a $10/irrigated acre/year fee. In 2025, the Sacramento County GSA Board will consider an additional Public Water System Fee (up to $1.58/acre-foot of water used) and a Base Parcel Fee (up to $35.59/year) to bring all groundwater users in the subbasin into the fee program.
