Sustainable Groundwater Management Act (SGMA)

SGMA is a landmark law that empowers local agencies to sustainability manage groundwater resources. In areas where groundwater users and local agencies are unable or unwilling to sustainably manage their groundwater, SGMA authorizes State Water Board intervention. California depends on groundwater for a major portion of its annual water supply, particularly during times of drought. The long-term planning required by SGMA will provide a buffer against drought and climate change, and contribute to reliable water supplies regardless of weather patterns in the State.
