How Bad is Water Use in California? March is the Worst So Far, Up 19%

/in , , /by /CalMattersby Rachel Becker

Californians emerged from the driest January, February and March on record with the biggest jump in water use since the drought began: a nearly 19% increase in March compared to two years earlier.

Despite the urgent pleas of water officials, California’s water use in March is the highest since 2015, standing in stark contrast to February, when residents and businesses used virtually the same amount of water in cities and towns as two years ago.

As Colorado River Shrinks, Pain of Drought to Spread

/in , , /by /E&E Newsby Jennifer Yachnin

Rolf Schmidt-Petersen knows what can happen when a water shortage hits: Reservoirs shrink and tempers flare.

“We had people literally throwing rocks, tomatoes when Elephant Butte went down,” recalled Schmidt-Petersen, director of the New Mexico Interstate Stream Commission. He was talking about a 2003 deal to release water from a reservoir in southern New Mexico and drop the lake by about 33 feet to assist farmers in the state and neighboring Texas.

Vegas Water Intake Now Visible at Drought-Stricken Lake Mead

/in , , /by /AP News

A massive drought-starved reservoir on the Colorado River has become so depleted that Las Vegas now is pumping water from deeper within Lake Mead where other states downstream don’t have access.

The Southern Nevada Water Authority announced this week that its Low Lake Level Pumping Station is operational, and released photos of the uppermost intake visible at 1,050 feet (320 meters) above sea level at the lake behind Hoover Dam.

“While this emphasizes the seriousness of the drought conditions, we have been preparing for this for more than a decade,” said Bronson Mack, water authority spokesman. The low-level intake allows Las Vegas “to maintain access to its primary water supply in Lake Mead, even if water levels continue to decline due to ongoing drought and climate change conditions,” he said.

The move to begin using what had been seen as an in-case-we-need-it hedge against taps running dry comes as water managers in several states that rely on the Colorado River take new steps to conserve water amid what has become perpetual drought.

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.

(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.)

Record Drought Conditions Across West Raise Concerns for Summer Dry Season

/in , , /by /NOAA by National Centers for Environmental Information

The current multi-year drought across the West is the most extensive and intense drought in the 22-year history of the U.S. Drought Monitor. Precipitation deficits during the first three months of 2022, across parts of the western U.S., are at or near record levels. As the climatological wet season ends across portions of the West, with below average snow cover and reservoirs at or near record-low levels, concerns for expanding and intensifying drought and water resource deficits are mounting.

During March, the average contiguous U.S. temperature was 44.1°F, 2.6°F above the 20th-century average. This ranked in the warmest third of the 128-year period of record. The year-to-date (January-March) average contiguous U.S. temperature was 36.3°F, 1.2°F above average, ranking in the middle third of the record.

The March precipitation total for the contiguous U.S. was 2.26 inches, 0.25 inch below average, and ranked in the driest third of the 128-year period of record. The year-to-date precipitation total was 5.66 inches, 1.30 inches below average, ranking seventh driest in the January-March record.

Temperatures were above average across much of the West and along the East Coast. California ranked sixth warmest for the January-March period.

Opinion: Despite Heavy Snow, We Must Seek a New Water Path

California is facing an indisputable fact: We need, in a big way, to get busy finding water alternatives to the long-indispensable Sierra Nevada snowpack.

Yes, we’ve been blessed by recent exceptional snowfall, perhaps a snowy feast after an extended water famine. But year to year, California’s frozen reservoir—the mountain snow whose melt feeds farming and quenches the thirst of Californians—is dwindling and increasingly unreliable as the climate changes.

California Reservoirs Continue to Rise After Major Winter Storms

California has seen big changes in reservoir levels so far this rainy season and the trend is up for the foreseeable future.

At the beginning of the water year for 2020-2021, some major reservoirs, such as Lake Oroville, were at record lows. California’s well-known reliance on water capture and transport was under severe strain until a record October storm provided quick relief.
