The Eastern San Joaquin County Groundwater Basin Authority (GBA) was established in 2001 to collectively develop locally supported projects to strengthen water supply reliability in Eastern San Joaquin County. Formed as a joint powers authority, GBA members agree to work cooperatively and to speak with one voice in their efforts to achieve reliable, affordable water supplies for the region.
San Joaquin County, likewise the rest of the State of California, is faced with the critical challenge of increasingly scarce water resources. Competition for limited surface water supplies from major rivers and the tremendous use of groundwater supplies, has increased the magnitude of this challenge.
Substantial progress has been made over the past several years with water resources continuing to build momentum through local achievements in groundwater banking and conjunctive use projects in Eastern San Joaquin County.
