Borrego Valley groundwater basin
Borrego Valley Groundwater Basin, located in the very southern region of California, is one of the driest basins in the state. With climate change predicted to have strong effects into foreseeable future, the region is viewed with a skepticism in the sustainable use of water at current rates of consumption. Both natural and man-made geographic divisions within this basin allow for a closer inspection of the various management techniques implemented throughout the years, and provide a basis for what may be pursued for an uncertain future. Borrego Valley is groundwater basin 7-24 with California's Colorado River hydrologic region. Geography of region The Borrego Valley Groundwater Basin is housed underneath the Borrego Valley, which lies in both San Diego and Imperial counties of southern California. It reaches from the San Ysidro Mountains in San Diego County, to the east, where it enters Imperial County. As of 2016, the California Department of Water Resources split this basin into two sub-basins, Borrego Springs and Ocotillo Wells. The total surface area of this basin is 150,000 acres (240 square miles), encompassing three aquifers throughout the valley. The natural landscape of this area consists mostly of shrublands, rocky outcrops and sediment, with sparse forested areas.
