Arizona and five other Colorado River Basin states are challenging a proposed pipeline that would divert to a booming Utah community almost as much river water as Tucson uses every year. Six of the seven river basin states — all but Utah — wrote to the U.S. Bureau of Reclamation on Tuesday, seeking a delay in publishing a final environmental review, and in making a final decision, on the Lake Powell pipeline.
A group of residents in a southern Nevada town that sits along the Colorado River are organizing a campaign to oppose a proposed pipeline that would divert billions of gallons of river water to southwest Utah, reflecting intensifying struggles over water in the U.S. West.
Arizona, Nevada and Mexico will again receive less water from the Colorado River next year under a set of agreements intended to help boost the level of Lake Mead, which now stands at just 40% of its full capacity.
The federal Bureau of Reclamation released projections on Friday showing that Lake Mead, the nation’s largest reservoir, will be at levels next year that continue to trigger moderate cutbacks in the two U.S. states and Mexico.
Every year, nearly 40% of California’s water used for drinking, agriculture, and irrigation comes from groundwater sources located in Northern California. During droughts, as much as 60% of water in California is sourced from groundwater. In addition, large quantities of California’s surface water (water found in lakes, rivers, stream, and reservoirs) provides a resource to citizens and farms in the state. However, since the 1922 Colorado River Compact, California is also able to draw up to 4.4 million acre feet per year from the Colorado River.
Charismatic is hardly the best word to describe the humpback chub, a fish with a frowny eel face jammed onto a sport fish body in a way that suggests evolution has a sense of humor. Nor did tastiness build a fan base for this “trash fish” across its natural habitat throughout the Colorado River Basin. But, in 1973, the humpback chub became famous by winning federal protection under the Endangered Species Act.
Even as a boy, I knew there was something unusual, even other-worldly, about living in the Imperial Valley.
We seemed so isolated, more connected to Mexico than California. In fact the valley’s largest city was Mexicali, just across the border, and we’d often walk across for cheap restaurant food. It was an hours-long, 100-mile automobile drive through treeless, boulder-strewn mountains to San Diego, the nearest California city of any size.
Arizona is getting a jump start on what will be a yearslong process to address a dwindling but key water source in the U.S. West.
Several states and Mexico rely on the Colorado River for drinking water and growing crops. But climate change, drought and demand have taken a toll on the river that no longer can deliver what was promised in the 1920s.
Arizona, New Mexico, Colorado, California, Utah, Wyoming and Nevada have been operating under a set of guidelines approved in 2007. Those guidelines and an overlapping drought contingency plan will expire in 2026.
For the second time, the state’s top water cop has directed the Western Slope’s oldest and most valuable water rights to be left off the once-a-decade abandonment list. That means hundreds of these mostly irrigation water rights have been granted immunity — even though they are no longer being used — from the threat of “use it or lose it,” further enshrining them in the state’s system of water administration and dealing a blow to the validity of the well-known adage.
Every 10 years, engineers and water commissioners from the Colorado Division of Water Resources review every water right — through diversion records and site visits — to see whether it has been used at some point in the previous decade. If it hasn’t, it could end up on the decennial abandonment list, which is scheduled to come out in July.
A draft report released today by the San Diego County Water Authority shows that building a new conveyance system to transport regional water supplies from the Colorado River Quantification Settlement Agreement is cost-competitive with other long-term options for meeting the region’s water needs.
The draft Phase A report is under review by water officials across the region. The Water Authority’s Board of Directors is expected to decide whether to move to Phase B at its July 23 meeting.
“By releasing this draft report – along with an independent review of key financial assumptions – we are trying to spark a thoughtful dialogue about our region’s water future,” said Dan Denham, deputy general manager for the Water Authority. “Given the long lead time for major water infrastructure projects, it’s important that San Diego County wrestle with these complex questions today so we can control our own destiny tomorrow.”

I read Mr. Hudson’s op-ed, “Clean Drinking Water, Considered, Part Five” and share much of his skepticism regarding the conversation happening along the Colorado River, its tributaries, and the special interests that surround it.
However, I did want to reach out and share some concerns with a few points raised in the editorial — specifically the comments on Imperial Valley.
