The San Joaquin Basin hydrologic region is one of California’s largest agricultural regions, producing corn, alfalfa, almonds, pistachios, processing tomatoes, grapes, and other agricultural commodities. While the urban population in this region continues to grow, there are numerous disadvantaged communities, not only small rural communities but also four of the most populous cities in the region.
