Lake Hodges is a lake and reservoir located within the city limits of San Diego, California. It is about north of Downtown San Diego, just north of the Rancho Bernardo community, and just south of the city's border with Escondido. When full, the reservoir has , a maximum water depth of , and of shoreline. Lake Hodges has a total capacity of 30,251 acre-feet of water. Lake Hodges is owned by the city of San Diego, supplies water to the San Dieguito Water District and Santa Fe Irrigation District, and its mailing city address is Escondido. Water level elevation in the lake is maintained at a maximum of above sea level, lower than the dam's maximum of spillway to ensure safe operations. The lake level can fluctuate significantly, depending upon the amount of runoff received from the San Dieguito River drainage basin. Interstate 15 crosses Lake Hodges via the Lake Hodges Bridge. Approximately west of the I-15 freeway bridge is a bicycle/pedestrian bridge which opened on May 15, 2009, and is the longest stressed ribbon bridge in the world. Lake Hodges Dam Lake Hodges Dam is a multiple-arch dam that sits on the San Dieguito River. It was commissioned by the Volcan Water Company and designed by John S. Eastwood. It was completed in 1918, and later purchased by the city of San Diego. Water from the Lake Hodges Reservoir services the customers of the Santa Fe Irrigation District and the San Dieguito Water District. The dam is 131 ft tall and 729 ft wide. In 2005, the San Diego County Water Authority, in conjunction with the City of San Diego, began work on a pipeline to connect Hodges Reservoir with Olivenhain Reservoir. The project was completed in 2012. The connection provides the ability to store of water at Hodges Reservoir for emergency use. This system is also used to provide electrical power to the grid during high demand times of the day. Water is pumped from Lake Hodges to Olivenhain at night when demand (and rates) for electricity is low. It is then flowed back down through generators during peak demand times. In 2019 a hypolimnetic aeration system was installed at the site of the former Reservoir keeper's house with a Speece cone installed at the bottom of the lake between that location and Alva canyon. Following the 2017 Oroville Dam crisis, the state of California conducted spillway inspections
