On August 29, 2014 the California Legislature passed comprehensive groundwater legislation contained in SB 1168, SB 1319 and AB 1739.  Collectively, those bills, as subsequently amended, enacted the "Sustainable Groundwater Management Act" (SGMA).  Governor Brown signed the legislation on September 16, 2014 and it became effective on January 1, 2015.

The Eastern San Joaquin Groundwater Authority was established as a public entity with the mission of the Authority providing dynamic, cost-effective, flexible and collegial organization to ensure initial and ongoing SGMA compliance within the Basin.
