It was constructed in the early 1900s to provide water for the city of San Diego. The reservoir is situated in a watershed that covers approximately 40 square miles and is fed by the Barrett Creek, which originates in the Laguna Mountains. The hydrology of the area is influenced by the Mediterranean climate, with most of the rainfall occurring in the winter months. The reservoir provides water to the city of San Diego, as well as to local farmers for irrigation. Recreational activities such as fishing, boating, and camping are also popular in the area. The snowpack providers in the region include the nearby mountains, which provide snowmelt runoff into the reservoir. The surface flow in the area is primarily provided by the Barrett Creek.
