California’s Heatwave Evaporates Billions of Gallons of Water from Reservoirs

/in , /by /Desert Sunby Damon Arthur and James Ward

California’s current record-breaking heat wave in July has caused hundreds of millions of gallons of water in Lake Shasta and other major reservoirs in Northern California to disappear into thin air.

During the first nine days of July, 3,392 cubic feet per second of water — or about 2.2 billion gallons — turned into vapor and floated away into the atmosphere off the man-made Lake Shasta. During just one day — July 3 — 288.8 million gallons of water alone evaporated.

U.S., Canada Reach New Agreement on Columbia River Hydropower, Water

/in , /by /The Oregonian

The U.S. and Canada said Thursday they have agreed to update a six-decade-old treaty that governs the use of one of North America’s largest rivers, the Columbia, with provisions that officials said would provide for effective flood control, irrigation, and hydropower generation and sharing between the countries.

The “agreement in principle,” reached after six years of talks, provides a framework for updating the Columbia River Treaty. It calls for the U.S. to keep more of the power generated by its dams while improving cooperation between the Bonneville Power Administration, which markets power from dams in the northwestern U.S., and Canadian utilities, to help avoid blackouts.

In an Era of Dam Removal, California is Building More

/in , /by /High Country Newsby Theo Whitcomb

When the largest dam removal in U.S. history began on the Klamath River this year, it seemed as if the era of dam building was over in the West. Just a month later, however, the federal government finalized $216 million dollars in funding for a controversial dam project south of the Klamath, adding to the $1 billion in direct grants already pledged to the project known as Sites Reservoir. Rights for the water are being distributed this summer.

This would be California’s first major new reservoir in half a century. The project will require building two main dams on a pair of streams that typically only run during big winter rains. Most of the water would come from much farther away, however: Filling the reservoir means piping water from the Sacramento River uphill, away from the Central Valley. If it’s built, the reservoir will inundate Antelope Valley, 14,000 acres of hilly grassland in the California Coast Range, northwest of Sacramento.

California Farmers Set to Cut Use of Colorado River Water, Temporarily Leaving Fields Dry

Farmers who grow hay in the Imperial Valley will soon be eligible to receive cash payments in exchange for temporarily shutting off water to their fields for up to two months this year.

Under a program approved by the board of the Imperial Irrigation District, farmers can now apply for federal funds to compensate them for harvesting less hay as part of an effort to ease strains on the Colorado River.

Water Reuse in the U.S.: a Comprehensive Look at Progress, Challenges, and Future Prospects

/in , /by /Smart Water Magazineby Olivia Tempest and Cristina Novo

Water reuse stands at the intersection of technology, policy, and public trust. The journey from basic agricultural reuse to advanced potable applications highlights the adaptability and potential of this approach.

Water scarcity and quality issues have increasingly pushed the boundaries of traditional water management practices. Among the innovative solutions gaining traction is water reuse, a concept that has evolved from agricultural and industrial applications to potable water supply. To explore the evolution, policy advancements, technological readiness, and future trends in water reuse in the United States, Smart Water Magazine spoke with three leading experts: Ben Glickstein, Director of Communications at WaterReuse Association; Eva Steinle-Darling, PhD, Water Reuse Technical Practice Director at Carollo Engineers; and Peter Grevatt, PhD, Chief Executive Officer of The Water Research Foundation.

California Supreme Court Reverses Public Utilities Commission on Water Surcharges

/in , /by /Courthouse News Serviceby Edvard Pettersson

The California Supreme Court on Monday reversed the state’s Public Utilities Commission’s 2020 order that stopped water companies from using certain surcharges when their revenue falls short because of conservation efforts.

The court agreed with a group of water companies that the commission hadn’t clearly informed them that it would consider eliminating the so-called decoupling mechanisms — initially prompted by years of drought and the need to conserve water — in the scoping memos for the yearslong rulemaking proceedings that culminated in the 2020 order.

Federally Unprotected Streams Contribute Most of the Water to U.S. Rivers

/in , /by /Science Newsby Claire Yuan

The dry-looking stream in your backyard may play a major role in feeding U.S. rivers.

Channels that flow only in direct response to weather conditions like heavy rain, called ephemeral streams, on average contribute 55 percent of the water in regional river systems in the United States, researchers report in the June 28 Science.

California Adopts Sweeping Statewide Water Conservation Framework

/in , /by /Los Angeles Timesby Hayley Smith

After years of deliberation, California water officials have adopted landmark rules that will guide future water use and conservation in the state.

According to officials, the Making Conservation a California Way of Life framework will help save 500,000 acre-feet of water annually by 2040 — enough to supply more than 1.4 million households for a year — and apply to the state’s largest water utilities, not individuals or households.

Hoping to Reduce Colorado River Dependency, Southern California Bets Big on Wastewater Recycling

/in , /by /Courthouse News Serviceby Edvard Pettersson

Can wastewater be made potable again on a mass scale? Water-district managers in California think so. At a wastewater treatment plant in Carson in the Los Angeles area, scientists and engineers have been fine-tuning their purification process since 2019.

The facility — known as the Grace F. Napolitano Pure Water Southern California Innovation Center — purifies 500,000 gallons of water each day with the goal of someday processing 300 times that amount, or 150 million gallons daily.
