SGMA in the Cosumnes Subbasin


SGMA in the Cosumnes Subbasin

Under California law, the Sustainable Groundwater Management Act (SGMA) requires the Cosumnes Subbasin to form a groundwater sustainability agency or agencies (GSAs) by June 30, 2017, and to have a groundwater sustainability plan (GSP) in place by 2022.

The following seven agencies filed with the state to form a GSA within the Cosumnes Subbasin:

  • Omochumne-Hartnell Water District (website)
  • Sloughhouse Resource Conservation District (website)
  • Galt Irrigation District (website)
  • Clay Water District (website)
  • City of Galt (website)
  • Amador County Groundwater Management Authority (website)
  • Sacramento County (website)

These GSAs are now engaged in a collaborative group, called the Cosumnes Subbasin SGMA Working Group, to discuss developing a roadmap for creating a groundwater sustainability plan. 

Learn how you can contact your local GSA Representative

Note: Elk Grove is in the South American Subbasin — not the Cosumnes Subbasin — and Sacramento Central Groundwater Authority (SCGA) is your local groundwater sustainability agency. For more information about SGMA in the South American Subbasin, visit the SCGA website at www.scgah2o.org.
