Risk of Colorado River Shortage is on the Rise, Could Hit Within 5 Years, Officials say

/in , , /by /Arizona Republicby Ian James

The risks of water shortages continue to grow along the Colorado River, which supplies about 40 million people from Wyoming to Arizona.

Federal water managers released projections Tuesday showing higher odds of shortages occurring within the next five years.

The Colorado River is in the 21st year of a severe drought that’s being compounded by hotter temperatures influenced by climate change, and the river’s flows have increasingly been insufficient to meet all the demands of cities and farms across the region.

Climate Change Likely to Keep Hammering Colorado River’s Biggest Reservoirs, Model Shows

/in , , /by /KUNC (Greeley, Colo.)by Luke Runyon

The Colorado River’s largest reservoirs are expected to keep struggling over the next five years due to climate change, according to the federal agency that oversees them.

The Bureau of Reclamation’s new modeling projections, which include this year’s record-breaking heat and dryness in some parts of the southwestern watershed, show an increasing likelihood of an official shortage declaration before 2026.

If dry conditions like the Colorado River Basin has seen since 2000 persist, the agency’s model shows an almost 80% chance of seeing an official shortage declaration by 2025. The chance of seeing the reservoir drop to a critically low level is about 20% in that same time period.

Lakes Mead, Powell at Risk Again from Drought Despite Major Conservation Efforts

For the second time in two years, federal officials are warning that Lake Mead could drop in five to six years to levels low enough to possibly warrant major Central Arizona Project water cutbacks to Tucson and Phoenix.

These warnings were ratcheted up significantly compared to forecasts made earlier this year. That’s due to the severely hot and dry weather that struck most of the West during the summer, including the hottest two months on record in Tucson and Phoenix in August and July, respectively.

The Colorado River is Awash in Data Vital to its Management, but Making Sense of it All is a Challenge

Practically every drop of water that flows through the meadows, canyons and plains of the Colorado River Basin has reams of science attached to it. Snowpack, streamflow and tree ring data all influence the crucial decisions that guide water management of the iconic Western river every day.

Why Some in Nevada See Utah Pipeline Plan as ‘First Salvo in Coming Water Wars’

/in , /by /Las Vegas Sunby Hillary Davis

Lake Powell isn’t in Southern Nevada. Rather, it’s about four hours away by car in southern Utah. But some environmentalists say the water consumption of St. George, Utah, and neighboring communities could have a direct and deleterious impact on the Las Vegas water supply.

For more than 20 years, negotiations among the seven states that rely on the Colorado River have avoided lawsuits, even as drought and population growth threaten the river’s flows.

That may change as a promise to rush the environmental review of a diversion project between the Colorado River’s upper and lower basins has six states suggesting lawsuits challenging the project could topple years of agreements.

Six Western States Blast Utah Plan to Tap Colorado River Water

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.

Arizona Endorses a Company’s Plan to Sell Colorado River Water to Queen Creek

/in , , /by /Arizona Republicby Ian James

Arizona’s top water regulator has endorsed a company’s proposal to take water from farmland near the Colorado River and sell it to the fast-growing Phoenix suburb of Queen Creek.

The plan, which still would require federal approval, has generated a heated debate about whether transferring water away from the farming community of Cibola could harm the local economy, and whether the deal would open the gates for more companies to buy land near the river with the sole aim of selling off the water for profit.
