California, Nevada and Arizona’s historic pact to cut their use of the Colorado River’s overtapped supplies should be enough to keep the basin’s massive reservoirs from hitting dangerously low levels — for now, a federal analysis reported today.
As droughts strain water supplies across Western states, some cities and farmers have struggled with mandatory cutbacks. Determining who gets cut is decided by the foundational pecking order of Western water: the older your claim to water, created as the country expanded westward, the better protected it is. When there’s a shortage, those with newer water rights have to cut back first, sometimes giving up their water completely before older claims lose a single drop.
The grass beneath the palm trees at the Foothills has no function other than to look lush and inviting for people driving up to the gated community’s entrance. The homeowners’ association there, like many that govern such developments dating to the 1980s and 1990s, was still sprinkling Colorado River water on about 50,000 square feet of turf this year.
As Western water managers get set to gather in Las Vegas this week, a long-sought deal to curtail water use along the cratering Colorado River still seems a ways off. Nearly six months have passed since Bureau of Reclamation Commissioner Camille Touton first asked the Western states to come up with a plan to cut back on water use from the river next year by as much as 30 percent, but a cohesive proposal from the seven states that pull from the Colorado that supplies water to some 40 million people has yet to emerge.
Management of the depleted Colorado River needs an overhaul, speakers at a University of Arizona-sponsored conference agreed. But at a conference called last week to observe the 100th anniversary of the interstate compact that divided river water rights among Western states, the speakers disagreed over whether the Colorado River Compact itself needs a major rework.
Sen. Michael Bennet (D-Colo.) is leading a letter signed by 14 other senators urging Agriculture Secretary Tom Vilsack to help Western states survive what they are calling a “22-year mega-drought” that is threatening farms and ranches across the West. “The American West is in crisis. Across the major basins of the American West … farm and ranch families hang in the balance as they grapple with a 22-year mega-drought,” they warned.
As temperatures on the West Coast soared into the triple digits in early September, power demand threatened to reach record levels — and utilities braced for grid problems. The California Independent System Operator (CAISO) warned of potential blackouts. Idaho Power Co., already hobbled by a pair of generator outages, prepared to cut power to some customers in Boise. Utilities in the desert Southwest expected surging demand to strain their grids.
In arid Western states, the climate is growing warmer and drier, leading to increased demand for water resources from humans and ecosystems. Now, the atmosphere across much of the U.S. is also demanding a greater share of water than it used to, according to a new study by a team from DRI, University of California, Merced, and Scripps Institution of Oceanography at UC San Diego.
Six states in the U.S. West that rely on the Colorado River to sustain cities and farms rebuked a plan to build an underground pipeline that would transport billions of gallons of water through the desert to southwest Utah.
In a joint letter Tuesday, water officials from Arizona, California, Colorado, Nevada, New Mexico and Wyoming urged the U.S. government to halt the approval process for the project, which would bring water 140 miles (225 km) from Lake Powell in northern Arizona to the growing area surrounding St. George, Utah.
