About the sweetwater river


The Sweetwater River is a 55-mile long river located in San Diego County, California. Historically, it was used by the Kumeyaay people for fishing and hunting. Today, it serves as a major source of water for the county. The river's hydrology is affected by both natural factors, such as rainfall, and man-made factors, including water diversion and dam operations. Specific reservoirs and dams on the Sweetwater River include Loveland Reservoir, Sweetwater Reservoir, and Lower Sweetwater Dam. These structures are used to store water for municipal and agricultural purposes. Recreational activities such as hiking, fishing, and camping are popular along the river, though access can be limited due to private property rights.
