A stretch of unusually wet months has erased drought across much of the Southwest. A briefing by climate experts spelled out how a snowy winter and rainy spring brought relief to a particularly parched region.
“Unlike some past presentations I’ve given for the Southwest,” said Brian Fuchs, a climatologist with the National Drought Mitigation Center, “This one actually has some good news in it.”
The federal government is designating $4 billion from the Inflation Reduction Act for drought mitigation work in the Colorado River basin.
On Wednesday, the Department of the Interior announced that total, indicating that $500 million will go to efficiency upgrades in the river’s Upper Basin states of Colorado, Utah, New Mexico, and Wyoming. Another chunk of IRA money will be set aside for direct payments to farmers and ranchers to forgo water deliveries from Lake Mead in the river’s Lower Basin, primarily in Arizona and California. Federal officials are not specifying how much money will be available for that first round of payments.
Researchers from Colorado State University focused on areas they call “late snow zones” – regions in the Western mountains where snow doesn’t typically melt until May or later.
They found that between 1984 and 2020, wildfire activity increased in 70% of these zones throughout the West. The mountain ranges studied included the Sierra Nevada, Cascades, Basin and Range, and Northern and Southern Rockies.
In the parched Colorado River basin, water managers are turning over every stone looking for ways to keep the taps flowing. Now, they’re finding more water in some unusual places – shower drains and toilet flushes.
At a sprawling sewage treatment plant in Carson, California, the occasional breeze delivers a pungent whiff of a reminder of how used water becomes “reused.” Here, the Metropolitan Water District of Southern California is planting the seeds for a massive new facility, where a multi-billion-dollar installation could help recycle wastewater and keep drinking supply flowing for the agency’s 19 million customers.
As the Colorado River shrinks, the seven states in the western United States that rely on it for water and power need to cut their use dramatically to keep the biggest reservoirs from getting critically low, according to federal analysts.
But a recent deadline for a plan to conserve an unprecedented amount of water came and went without many specifics from either the states or the federal government on how to achieve the cutbacks.
As climate change continues to sap the Colorado River’s water, some users face serious legal risks to their supplies, according to a new analysis by researchers in Colorado and New Mexico.
Declining flows could force Southwest water managers to confront long-standing legal uncertainties, and threaten the water security of Upper Basin states of Colorado, Wyoming, Utah and New Mexico.
Climate change, growing urban populations and fragile rural economies are top of mind. Some within the basin see a window of opportunity to argue for big, bold actions to find balance in the watershed. Others say the best path forward is to take small, incremental steps toward lofty goals, a method Colorado River managers say has worked well for them for decades.
It’s late May in Wyoming. It snowed last night, and more snow is predicted. That’s why it’s good that Big Piney Rancher Chad Espenscheid is behind the wheel of the truck. The roads are sloppy and Middle Piney Creek is running high. “Speaking of water,” he says, laughing. “Yeah, seems like it’s starting to flood,” I observe. “Yeah, it’s just wet.” That wetness is nerve-wracking for ranchers like Espenscheid. “It’s been a cold, long winter,” he says. “The cows and calves are really needing some sunshine about now. We got quite a bit of sickness going on around the valley.”
The Colorado River is short on water. But you wouldn’t know it by looking at a slate of proposed water projects in the river’s Upper Basin states of Colorado, Utah and Wyoming. The river and its tributaries provide water for 40 million people in the Southwest. For about the last 20 years, demand for water has outstripped the supply, causing its largest reservoirs to decline.
High snowpack in the southern Rocky Mountains this winter will likely stave off a shortage declaration in the Colorado River watershed in 2020, relieving pressure on water managers attempting to navigate future scarcity. New data from U.S. Bureau of Reclamation models show a lessened risk of a key Colorado River reservoir dropping far enough to trigger a first-ever shortage declaration. Snowpack in the Upper Colorado River Basin is at 138 percent of the long-term median, a level not seen in mid-March since 1997.
