The South American Subbasin

 Water is vital to the economy, the environment, and the quality of life in Sacramento County. While this precious resource is visible every day in the American, Sacramento and Cosumnes Rivers, water underground is no less important, providing about half of the region’s water supply. Groundwater serves the needs of cities, farms and businesses and provides high quality drinking water to urban and rural residents, all while helping to sustain vital ecosystems.
