Water Supply

The water delivered to Santa Fe Irrigation District customers is obtained from a variety of sources. To learn about those sources, visit our Water Sources page. Approximately 65 percent of the potable water is obtained from imported water sources from our wholesalers, the San Diego County Water Authority (SDCWA) and the Metropolitan Water District of Southern California (MWD). MWD imports its water from two sources: a 242-mile-long aqueduct which transports Colorado River water from Lake Havasu to Southern California and a 444-mile-long aqueduct that transports water from the Sacramento-San Joaquin Delta in Northern California to Lake Skinner located in Riverside Country.

Local Water

About 30 percent of the water delivered is from local water supplies, including Lake Hodges and the San Dieguito Reservoir. Five percent of the water delivered is recycled water obtained from the San Elijo Joint Powers Authority and used in the City of Solana Beach for irrigation purposes.

In 2022, the City of San Diego began emergency repairs to Lake Hodges Dam, severely limiting the amount of local water SFID can use in 2023 and future years until a new dam can be constructed. Read the Lake Hodges Fact Sheet here to learn more about the potential impacts.

The Santa Fe Irrigation District is deeply involved in programs to protect its water sources, and continually investigates ways to increase its local supplies of water. Programs include lake management at the San Dieguito Reservoir, recycled water, watershed outreach and education, and joint projects such as the SDCWA Emergency Storage Project.
