What is Groundwater ?
Groundwater is the world's largest freshwater resource and due to over extraction, levels have declined in many regions causing extensive social and environmental impacts. Groundwater management seeks to balance and mitigate the detrimental impacts of development, with plans commonly used to outline management pathways.
The Groundwater Sustainability Agencies (GSA’s) formed as a result of the Sustainable Groundwater Management Act (SGMA), passed by the California Legislature in 2014. SGMA requires all medium and high priority groundwater basins in California to develop a plan to be managed sustainably by 2020 (high priority basins) or 2022 (medium priority basins). The San Gorgonio Pass Subbasin is a medium priority basin, as defined by the California Department of Water Resources (DWR).
Subbasin map overview
Geographic area of the subbasin
The Subbasin roughly covers territory between the eastern edge of the City of Banning on the west, and the community of Verbenia on the east. It includes the community of Cabazon. The Morongo Band of Mission Indians Reservation is completely contained within the Subbasin.
The Subbasin does not receive a lot of natural precipitation. Most of the inflow into the Subbasin comes in the form of runoff from the mountains to the north and south. This runoff is the result of rainfall and snowmelt. The population overlying the Subbasin is not large; hence there is not a lot of pumping within the Subbasin.
