Lower Otay Reservoir

The Lower Otay reservoir serves as a terminal reservoir for a significant sized watershed, imported water aqueducts and a source of local water for the Otay Drinking Water Treatment Plant. For these reasons, the reservoir intentionally operates at a higher capacity level than many of the other City reservoirs which are used primarily for storage and rely on local rain and snow runoff.


In 1897, the first Lower Otay Dam was completed by the Southern California Mountain Water Company. The Lower Otay Reservoir was connected to the City of San Diego's water system in 1906 via the Bonita Pipeline. Following heavy rains, the dam burst in 1916 and the Otay Valley was flooded. The dam was rebuilt in 1918 and renamed Savage Dam. When full, Lower Otay Reservoir has 1,100 surface acres, a maximum water depth of 137.5 feet, and 25 shoreline miles. Lower Otay Reservoir has a water storage capacity of to 47,066.9 acre feet. Water levels are monitored weekly. The reservoir is the home of the United States Olympic Training center for rowing sports.Map of Otay Reservoir

In addition to fishing from boats, patrons can use float tubes, waders, or simply fish from shore. Use of float tubes is restricted to within 150 feet or less from shore. Float tubers must wear chest waders and have a Coast Guard approved personal flotation device readily available at all times, and have 144 square inches of international orange visible at least 12 inches above the water line. They must also possess a horn or whistle to warn approaching craft. Any float tube that uses oars or has a motor must purchase a private boat use permit. Dogs are not allowed on any boats.
