On September 16, 2014, Governor Jerry Brown signed into law a three-bill legislative package, the Sustainable Groundwater Management Act (SGMA), creating California's first "framework for sustainable, groundwater management. SGMA empowers local agencies to form Groundwater Sustainability Agencies (GSAs) to manage basins sustainably and requires those GSAs to adopt Groundwater Sustainability Plans (GSPs) for crucial groundwater basins in California.
The City of Big Bear Lake Department of Water and Power (BBLDWP), the Big Bear City Community Services District (BBCCSD), and the Big Bear Municipal Water District (BBMWD), each of whom are eligible local agencies under the SGMA, formed the Bear Valley Basin Groundwater Sustainability Agency (BVBGSA) under a joint powers agreement on April 26, 2017. The joint powers agency formed under that agreement then approved becoming a GSA for the Bear Valley Groundwater Basin by holding a public hearing and adopting a resolution on May 25, 2017. The GSA designation covers the entire Bear Valley Basin.
