Main Office

Lillian Rice designed this office in 1923 for the newly formed district, which was to bring water from Lake Hodges to Rancho Santa Fe, a key selling point for the village. The building was recently restored to its original appearance and is the only remaining example of Rice's treatment of commercial property to reflect the blend with the style of her homes.

R.E. Badger Filtration Plant

The San Dieguito Water District and Santa Fe Irrigation District jointly own and operate the R.E. Badger Filtration Plant. The plant receives imported water by pipeline from Lake Skinner located near Hemet in Riverside County and local water from Lake Hodges located just south of Escondido and the San Dieguito Reservoir located in Rancho Santa Fe.
Lake Skinner is a blend of water imported by the Metropolitan Water District of Southern California from two separate sources: a 242-mile aqueduct brings Colorado River Water from Lake Havasu and the 444 mile California Aqueduct brings water from the State Water Project originating in Northern California.
Rancho Cielo Raw Water Pump Station

The The Rancho Cielo Raw Water Pump Station was constructed on Del Dios Highway to pump raw water from Lake Hodges directly to the R.E. Badger Filtration Plant.
The Lake Hodges Dam Flume, a portion of which is shown above, provided all the water to the District until 1964, when Colorado River water augmented the area's supply. The flume was the only outlet to Lake Hodges Dam. The flume was taken out of service in August 2003 and replaced with a new 36-inch water line. Local water is still able to enter the San Dieguito Reservoir through a new 18-inch waterline that was installed in the old flume west of Del Dios Highway. The new 36-inch and 18-inch pipelines and the pump station were dedicated in August 2004.
Lake Hodges

Lake Hodges rests on the San Dieguito River that empties into the ocean at Del Mar. The construction of Lake Hodges dam expanded the reservoir capacity. It was funded by the Santa Fe Railroad Company. It was designed by John S. Eastwood. The Bent Bros. completed construction in 1918. In 1925, the City of San Diego purchased the dam. The Santa Fe Irrigation District shares water ownership rights in Lake Hodges with the San Dieguito Water District, and pays the City of San Diego for operations and maintenance of the Lake.
Lake Hodges Reservoir's capacity is 30,251 acre feet. It has 1,234 surface acres when full. Its maximum water depth is 115 feet and it has 27 shoreline miles.
Lake Hodges is renowned for its impressive bass fishing.
