Lower Otay Reservoir is a reservoir in San Diego County, southern California. It is flanked by Otay County Open Space Preserve in the San Ysidro Mountains on the east, and the city of Chula Vista on the west.
The reservoir is formed by impounding the waters of the Otay River, behind Savage Dam, completed in 1918, and is the terminus for both the San Diego Aqueduct, which transports imported water from the Colorado River. The dam and reservoir are owned by the City of San Diego.
Lower Otay Reservoir was originally created in 1897 after the construction of the Lower Otay Dam by the Southern California Mountain Water Company. The original dam was a rock fill type of 125 feet (38 m) high. That dam gave way in January 1916 following heavy rains which affected most of Southern California flooding the Otay Valley with a wall of water ranging from 20 to 100 feet (6.1 to 30.5 m) in height during the event, killing more than 14 people. The flood swept away entire farms and buildings, including the Montgomery residence at Fruitland near the mouth of the river, where John J. Montgomery had built his initial series of manned glider designs. The rains were ostensibly the work of the "rainmaker" Charles Hatfield, who had been hired by the City of San Diego to assist in increasing rainfall to fill nearby Morena Reservoir. He was never charged with any crimes. Following this the present Arch-gravity dam was built. In 1934, it was named in honor of Hiram Newton Savage, the city engineer who supervised its construction.
An Curtiss SB2C Helldiver plane was spotted in the lake in February 2009 by a bass fisherman. On May 28, 1945, it had been on a practice bombing run from a nearby aircraft carrier when a stalled engine forced an emergency landing in the reservoir. Divers examined the plane on July 23, 2009, to see if it could be salvaged for museum display, and it was raised on August 20, 2010.
