San Gorgonio Pass Subbasin SGMA Groundwater Sustainability Plan 

On January 25, 2022, the Groundwater Sustainability Plan (GSP) for the San Gorgonio Pass Subbasin was adopted by the GSAs and submitted to the California Department of Water Resources (DWR) for review. In a letter dated October 26, 2023, DWR determined that the GSP met the requirements of SGMA and approved the plan. DWR informed the GSAs they would be required to assess and update the GSP every five years, with the first plan update due to DWR by January 25, 2027. To view the GSP for the San Gorgonio Pass Subbasin, visit the San Gorgonio Pass Subbasin SGMA website.
