US Projections on Drought-Hit Colorado River Grow More Dire

/in , , /by /AP News

The U.S. government released projections Wednesday that indicate an even more troubling outlook for a river that serves 40 million people in the American West.

The Bureau of Reclamation recently declared the first-ever shortage on the Colorado River, which means Arizona, Nevada and Mexico will get less water than normal next year. By 2025, there’s a 66% chance Lake Mead, a barometer for how much river water some states get, will reach a level where California would be in its second phase of cuts. The nation’s most populated state has the most senior rights to river water.

Two major California water agencies have settled a lawsuit that once threatened to derail a multi-state agreement to protect a river that serves millions of people in the U.S. West amid gripping drought.

The Imperial Irrigation District, the largest single recipient of Colorado River water, sued the Metropolitan Water District twice in the past two years. The agencies announced Monday they have reached a settlement that resolves both lawsuits.

As Arizona’s population continues to swell by record numbers, cities and towns housing the transplants are looking for ways to increase their water supply.

That search has pitted the growing Town of Queen Creek against counties along the Colorado River. Cibola, Arizona in La Paz County sits near the border with California directly on the river. The population ranges from 250 to 350 people depending on the time of year according to La Paz County Supervisor Holly Irwin.

The Colorado River Basin is enduring two decades of drought, and water shortages are on the horizon. But scientists say this isn’t the worst-case scenario. The region has undergone longer, deeper droughts in the past. KNAU’s Melissa Sevigny spoke with paleoclimatologist Matt Lachniet of the University of Nevada-Las Vegas about how knowing the past can help us plan for a warmer, drier future.

Opinion: A Coachella Valley Date Farmer on What Happens When We Ask Too Much of the Colorado River

Even as she was going blind, my mom, ever the poet, delighted in sitting out among the palms and birds, and enjoying and visualizing the scene, as I irrigated my date gardens in the Coachella Valley.

In her 1997 poem, “Colorado Water,” she wrote:

The palm said, “My clover is cool around my bole, over my hidden roots.
My fronds clatter, crash
like waves in the far off sea.”

It’s no secret the Colorado River Basin is experiencing one of its worst droughts in record history.

Now, hydrologists are minimizing water usage next year. Lake Mead and Lake Powell are at their lowest water elevation levels ever, and it’s only expected to get worse as we head into 2022, according to Wade Noble, who serves on the general council for four of Yuma’s irrigation districts.

La Niña Responsible for Megadroughts in North and South America, Study Finds

/in , , /by /Courthouse News Serviceby Jon Parton

La Niña, the climate event that causes water to be colder than normal in the eastern Pacific, has now been shown by new research released Monday to be responsible for simultaneous megadroughts in the North and South American Southwest over the past 1,000 years.

Megadroughts are extended periods of drought that last at least 20 years. In a study published in the journal Nature, researchers found that these megadroughts occurred simultaneously in the North American and South American Southwest “regularly” and often during a La Niña event.

Why Water Cuts Are Coming to Arizona, Nevada, and New Mexico

/in , , /by /Bloomberg Lawby Cordie Qualle

The Bureau of Reclamation, the agency charged with water resources management for the West at the federal government level, announced unprecedented Tier 1 cuts in water deliveries from Lake Mead on the Colorado River to Arizona, Nevada, and Mexico in 2022. The Tier 1 cuts will reduce water deliveries due to historic low water levels in Lake Mead.

California deliveries are not impacted by this announcement due to senior water rights, but they could be coming if water levels continue to drop. The Colorado River watershed and most western river watersheds that feed reservoirs with snowmelt are not producing as much runoff as they have historically due to the warming atmosphere affecting snow elevations and dryer and warmer soil and air temperatures.
