Lake Hodges-Hodges Reservoir-Hodges Dam

Repair Work on Hodges Dam to Begin

/in , /by

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. “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.

Water transfers to maximize savings

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.

California, Arizona and Nevada Face Major Water Cutbacks From the Colorado River

/in , , /by /NPR

Because of the megadrought that’s gripping the southwestern United States, the federal government is cutting back how much water it delivers to California, Arizona and Nevada by a lot, about as much as Las Vegas uses in a year. It’s something water managers never thought they’d have to do. Alex Hager reports on the Colorado River from member station KUNC in Greeley, Colo., and joins us now to explain what’s going on. So decades ago, the U.S. built huge dams on the Colorado River specifically to store water as insurance against droughts. Why isn’t that system working now?

Deliveries to Be Cut as Lake Powell Approaches Crisis Level

/in , , /by /Las Vegas Sunby Jessica Hill

Lake Mead’s “bathtub ring” is set to become even more pronounced this year.

The lingering drought is the overriding reason that the lake’s water level will fall again in 2022, but it’s also because less water will be released upstream on the Colorado River from Lake Powell.

This month, the seven Colorado River Basin States — Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming — agreed with federal officials’ recommendations to institute a 480,000 acre-foot reduction from Glen Canyon Dam on Lake Powell to reduce the risk of the lake declining below 3,490 feet.

The Olivenhain Municipal Water District recently completed the Manchester Avenue Potable Water Pipeline Project. In total, 3,700 linear feet of aged potable water pipeline was replaced along Manchester Avenue, Rancho Santa Fe Road and Encinitas Boulevard.

The pipelines previously serving water in this area were installed in 1961 and were approaching the end of their lifespan. OMWD takes a proactive approach in repairing and replacing aging water infrastructure to avoid leaks and ensure the continuation of uninterrupted water service to its customers. In the third year of drought in California, projects like this pipeline replacement, help save potable water and reduces costs to ratepayers.

“Emergency leaks are very costly, can waste millions of gallons of water, and can be disruptive to surrounding communities,” said Bob Topolovac, OMWD board director. “The investments we made to prevent these emergencies will benefit our ratepayers well into the future.”

Pipelines replaced included:

  • Approximately 1,900 linear feet of 12-inch pipeline in Manchester Avenue from Colony Terrace north to Encinitas Boulevard
  • Approximately 450 linear feet of 12-inch pipeline in Encinitas Boulevard west of Rancho Santa Fe Road
  • Approximately 500 linear feet of 12-inch pipeline in Rancho Santa Fe Road north of Encinitas Boulevard
  • Approximately 850 linear feet of eight-inch pipeline in South Rancho Santa Fe Road

To minimize the impact on the surrounding community, construction took place mainly at night. The project was completed on time and with no major disruptions or water outages to the impacted community. OMWD coordinated with the City of Encinitas on a traffic management plan to mitigate construction traffic, and there were no significant traffic impacts.

Energy Shift Creates Opening for ‘World’s Largest Batteries’

/in , , /by /AP News by John Flesher

Sprawled like a gigantic swimming pool atop a bluff overlooking Lake Michigan is an asphalt-and-clay pond holding enough water to produce electricity for 1.6 million households.

It’s part of the Ludington Pumped Storage Plant, which uses simple technology: Water is piped from a lower reservoir — the lake, in this case — to an upper one, then released downhill through supersized turbines.

Supporters call these systems “the world’s largest batteries” because they hold vast amounts of potential energy for use when needed for the power grid.

The hydropower industry considers pumped storage the best answer to a question hovering over the transition from fossil fuels to renewable energy to address climate change: where to get power when the sun isn’t shining or the wind isn’t blowing.

(Editor’s Note: The San Diego County Water Authority and the City of San Diego are partnering on the proposed San Vicente Energy Storage Facility project. More information: www.sdcwa.org/projects/san-vicente-pumping-facilities/)

Seizing the Water Infrastructure Moment Nationally and Locally

/in , , /by /Brookingsby Joseph W. Kane and Andy Kricun

Aging and undersized sewers, contaminated drinking water, and lead-tainted pipes imperil millions of households and communities nationally. At the same time, more severe flooding and drought conditions have exacerbated the nation’s water infrastructure deficit. Decades of inaction and underinvestment—particularly at a federal level—have multiplied these and other water infrastructure challenges, but the recently passed Infrastructure Investment and Jobs Act (IIJA) holds promise to address them via an infusion of more than $57 billion to states and localities over the next five years.
