This Giant ‘Inland Ocean’ is Southern California’s Last Defense Against Drought

Mechanical engineer Brent Yamasaki set out amid the recent blistering heat wave to take stock of the giant dams, pumps and pipes that support Diamond Valley Lake in Riverside County, the largest storehouse of water in Southern California.

The reservoir, which he helped build 25 years ago, is 4½ miles long and 2 miles wide and holds back nearly 800,000 acre-feet of water — so much that it would take 20,000 years to fill it with a garden hose.

San Diego County Water Authority Confirms Region ‘Drought Safe’ This Summer

Despite continued hot and dry conditions in California, the San Diego region is protected from drought impacts this summer and through 2045, the San Diego County Water Authority announced Monday.

According to a statement released by the Water Authority, “no shortages or regional water-use mandates are in the forecast, the result of three decades of strategic investments that create an aquatic safety net for San Diego County’s $253 billion economy and quality of life for 3.3 million residents.”

Gary Croucher, Water Authority Board chairman, thanked San Diegans for their efforts to “make sure that we have enough water to meet the region’s needs now and for decades into the future.”

New Bill Would Make it Easier to Transfer Water Throughout California

Growers are dealing with severe cutbacks in the surface water deliveries they normally receive from reservoirs.

The lack of steady irrigation has already impacted spring cropping decisions made by farmers.

Drought: Emergency Project Being Built to Protect California Water Supplies

In a new symbol of California’s worsening drought, construction crews are putting the finishing touches on a $10 million emergency project to build a massive rock barrier through part of the Delta in Contra Costa County to preserve water supplies for millions of people across the state.

The 800-foot long barrier — the size of San Francisco’s Transamerica Pyramid laid on its side — is essentially a rock wall, 120 feet wide, built in water 35 feet deep.

Its purpose: To block salt water from the Pacific Ocean and San Francisco Bay from flowing too far east and contaminating the huge state and federal pumps near Tracy that send fresh water south to 27 million people — from San Jose to Los Angeles — and to millions of acres of farmland in the Central Valley and beyond.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Here Are Some Things to Know About the Extreme Drought in the Western U.S.

Almost half of the U.S. has been in a drought since the start of 2021.

Compounding factors, including low rainfall and snowpack, climate change and persisting droughts from previous years, have escalated into extreme dryness.

The prolonged dryness means low water levels are endangering fish species in Oregon and Colorado, 30% of California’s population is in a drought emergency, and the nation’s two biggest reservoirs on the Colorado River — Lake Powell and Lake Mead — are two-thirds empty.

If Lake Powell’s Water Levels Keep Falling, A Multi-State Reservoir Release May Be Needed

Lake Powell’s water level is the lowest it’s been in decades, and the latest 24-month projections from the Arizona and Utah reservoir show that it’s likely to drop even further — below a critical threshold of 3,525 feet by next year.

Biden Picks Career Water Policy Adviser to Lead Water Agency

Camille Touton, a veteran congressional water policy adviser, has been nominated to lead the agency that oversees water and power in the U.S. West.

President Joe Biden on Friday nominated Touton to be the next commissioner of the U.S. Bureau of Reclamation. If confirmed, the Nevada native will be a central figure in negotiations among several states over the future of the Colorado River.

Drought, climate change and demand have diminished the river that supplies 40 million people, and the agency is expected to mandate water cuts for the first time in 2022.

Lake Oroville’s Depleted Water Levels May Force Power Plant to Shut Down for the First Time Ever

Water lines on the banks of Lake Oroville in Butte County have depleted so rapidly that the reservoir’s hydroelectric power plant may have to shut down for the first time ever, straining an already encumbered power grid during the hottest part of the summer, California officials announced Thursday.

Since 1967, the Edward Hyatt Power Plant has been a crucial source of electricity for the area and usually has the capacity to power up to 800,000 homes, pumping water from the lake through its underground facilities, according to CNN. However, water levels are currently approaching 700 feet, exacerbated by a severe drought and triple-digit temperatures.

Irrigation Districts Agree to Send Water from New Melones South to Drought-Stricken Farmers

As much as 100,000 acre-feet of water — enough to meet the annual demand of more than 40,000 Tuolumne County residents for at least five years — that’s currently stored in New Melones Reservoir could soon be sent south to aid drought-stricken farmers under an agreement between the Oakdale and South San Joaquin irrigation districts.

On Wednesday, the districts announced their respective boards had approved the proposal that would benefit agricultural contractors on the west side of the San Joaquin Valley who’ve been cut off from their typical annual water supplies through the federal Central Valley Project due to the drought conditions.

Wells Are Failing in Southeastern Madera County. What to Know About the Water Situation

On Sunday evening, a well motor failed in a Madera Ranchos community water system that serves around 1,000 homes. Last week, another well pump stopped working in Parksdale, southeast of Madera. Neither community has lost water service. Both are experiencing low pressure. Madera County Public Works runs both water systems. From Madera Acres to the Bonadelle Ranchos, private wells are running dry at an alarming rate. Self-Help Enterprises, an organization that supports communities with water challenges, has been tracking the problem.
