Brian Caldwell has been leading photo tours on Lake Hodges for years, with many spectators drawn in by wildlife. But after an inspection in 2022, the state mandated the water level be dropped, and Caldwell noticed a change in the wildlife population.
The city will release around 250 million gallons of water from Hodges Reservoir into the San Dieguito River over a two-day period starting Monday. The water release, using valves in Hodges Dam, will begin Monday and is intended to reduce the reservoir’s elevation by around two feet to 275 feet, according to the city.
SAN DIEGO – Due to past rainfall and a state mandate with regard to water level, the City of San Diego is scheduled to release approximately 250 million gallons of water from Hodges Reservoir into the San Dieguito River. This will lower the current water level by approximately 2 feet. The water release, using valves in the dam, is scheduled to begin Monday, Nov. 28, 2022, and will continue for approximately two days until the reservoir elevation is approximately 275 feet.
The lower water levels people might be seeing at Lake Hodges are not drought-related, but instead are due to the ongoing work repairing the 100-year-old Lake Hodges Dam. The emergency work on the dam began in May and is expected to be completed by October.
In the coming weeks, the City of San Diego will begin emergency repairs on the Lake Hodges Dam at the Hodges Reservoir in Escondido outside of Rancho Santa Fe.
During a recent inspection, the city identified areas in the dam wall that require repair and need be sealed. In order to complete the work, the water level of the reservoir needs to be lowered by about 18 feet from its current level to an elevation of 275 feet.
The repair project is expected to continue for an estimated five months.
As part of continuing efforts to maintain and invest in City of San Diego infrastructure, repair work starts within the next two weeks on Hodges Dam, at the Hodges Reservoir north of Rancho Bernardo.
“It’s been over a century since Hodges Dam was constructed, and we are making significant investments to maintain this vital asset,” said Alia Khouri, Deputy Chief Operating Officer.

“It’s been over a century since Hodges Dam was constructed, and we are making significant investments to maintain this vital asset,” said Alia Khouri, Deputy Chief Operating Officer. “Projects like this one are crucial for the City’s aging infrastructure system in order to maintain the safe and efficient delivery of City services.”
During a recent inspection, staff identified areas in the dam wall that require repair and need to be sealed. To access these areas, the water level of the reservoir needs to be lowered by approximately 18 feet from its current level to an elevation of 275 feet. The reservoir may need to be lowered below 275 feet if additional areas needing repair are identified during the project. The repair project is expected to continue for an estimated five months.

The primary function of Hodges Reservoir is to store water for potable use. The City is working with its regional water agency partners on a plan to draw down the reservoir level to maximize water savings. Most, if not all, of the water will be transferred to other reservoirs, while some water may be released into the San Dieguito River.
“The City of San Diego is committed to maintaining Hodges Dam to ensure the protection of our water resources and public enjoyment of the reservoir,” said Juan Guerreiro, Interim Director of the City’s Public Utilities Department. “We appreciate the public’s patience while we complete the project.”
To access areas of the Hodges Dam for repairs, the water level of the reservoir needs to be lowered by approximately 18 feet from its current level to an elevation of 275 feet. As a result of the lower water level, the Hodges Reservoir will be closed for recreation while the repair project is underway. Boating and fishing will still be available at other City of San Diego reservoirs. The San Dieguito River Park trails and facilities around Hodges Reservoir will not be impacted during the drawdown or dam construction work.
Operated and maintained by the San Diego Public Utilities Department, the reservoir currently serves the San Diego County Water Authority, San Dieguito Water District, and Santa Fe Irrigation District, and the City of San Diego. San Diego operates nine reservoirs, including Hodges.
(Editor’s note: The City of San Diego, San Dieguito Water District, and the Santa Fe Irrigation District are three of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region.)
For years, pairs of grebes would zoom across the water at Lake Hodges in a dazzling mating dance, and then build their nests on mats of dried brush suspended above the waterline.
Because of recent heavy rainfall, the city of San Diego Saturday began releasing about 923 million gallons of water from Hodges Reservoir into the San Dieguito River, which may eventually lead to the ocean, city officials said.
The dam release began at about 11 a.m. Saturday and will continue for about seven days or until the reservoir elevation is near 295 feet, spokesperson José Ysea said.
For safety reasons, the California Division of Safety of Dams has determined that the water level at Hodges Reservoir should not exceed 295 feet, which is 20 feet below spillway elevation, Ysea said. This requires periodic water releases from Hodges Reservoir.
You might not think ‘baking skills’ would come in handy to fix a recent problem at the Lake Hodges Hydroelectric and Pump Station Facility. But those skills, along with initiative and ingenuity, were demonstrated by San Diego County Water Authority staff as part of the creative and complex repair.
The facility connects the City of San Diego’s Hodges Reservoir with the Water Authority’s Olivenhain Reservoir. The connection provides the ability to store up to 20,000 acre-feet of water at Hodges for emergency use.
