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.
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.
Public Comment Period Opens for Groundwater Sustainability Plans
Groundwater sustainability plans that have recently been submitted to the Department are now posted on the DWR SGMA Portal.
These plans are open to public comment for 75 days after the posted date. Information about how to comment on the plans can be found in a fact sheet in English and Spanish. Public comments are welcomed and encouraged. A SGMA Portal account is not necessary to submit comments.
Final Groundwater Sustainability Plan
The Final Groundwater Sustainability Plan (GSP) (subject to GSAs’ formal adoption and submittal to DWR) is available to view/download.
