Colorado River Reservoirs Are So Low, Government Is Delaying Releases

With long-term severe drought continuing to take a toll on the Colorado River, the federal government is expected to announce on Monday that it will retain some water in one of the river’s major reservoirs to temporarily stave off what it called increased uncertainty in water and electricity supplies.

The anticipated decision to keep more water in Lake Powell on the Arizona-Utah border, rather than releasing it downstream to the other major reservoir, Lake Mead near Las Vegas, comes as both are at record-low levels after 20 years of drought.

As Drought Shrinks the Colorado River, a SoCal Giant Seeks Help From River Partners to Fortify Its Local Supply

Momentum is building for a unique interstate deal that aims to transform wastewater from Southern California homes and business into relief for the stressed Colorado River. The collaborative effort to add resiliency to a river suffering from overuse, drought and climate change is being shaped across state lines by some of the West’s largest water agencies.

Interior Department May Limit Lake Powell Water Releases to Protect Infrastructure, Hydropower Production

In an effort to protect the infrastructure at Lake Powell and the ability of Glen Canyon Dam to generate electricity, the U.S. Department of the Interior may keep nearly a half million acre-feet of water in the Utah reservoir instead of releasing that water to the Lower Basin states of Arizona, California and Nevada this year as scheduled.

Although it’s not clear the Department of Interior proposal would have any immediate impact on Colorado, it highlights the challenges of balancing a system relied on by 40 million people that has been taxed by water users and climate change. It’s also a reminder of the dire assessment of water in the West amid the driest two-decade stretch in the past 1,200 years.

Powell’s Looming Power Problem

Thirty-nine years ago, due to record-breaking snowfall in the Upper Colorado River Basin, Lake Powell rose substantially, catching river managers off-guard. By late June, the reservoir was nearly overflowing, forcing operators — for the first time ever — to rely on the spillways. Instead of giving relief, that precipitated a new crisis, as a phenomenon called cavitation sent shockwaves through the spillways’ innards, tearing through the concrete and then the sandstone, putting the colossal Glen Canyon Dam in peril.

Arizona Will Endure Another Hot, Dry Spring as Drought Persists

People in Arizona hoping for a break this spring from the drought gripping the state will be disappointed, with climatologists calling for minor to exceptional drought conditions, what one calls the state’s “new normal.”

The spring outlook released this month by the National Oceanic and Atmospheric Administration predicted the largest drought coverage seen in the U.S. since 2013, with as much as 60% of the continental U.S. facing drought conditions.

“This outlook that NOAA is saying, that we’re going to develop or have worsening drought, it’s not surprising, it’s not unexpected,” said Erinanne Saffel, Arizona’s state climatologist.

Lake Powell Continues to Disappear as Colorado Hits Pause on Plan to Prop Up Levels

The Glen Canyon Dam may be one step closer to losing its ability to generate hydropower after water managers in Colorado announced last week that they will stop exploring one proposal to prop up the rapidly depleting levels in Lake Powell.

The plan — known as demand management — would compensate farmers and ranchers for voluntarily stopping irrigation on a temporary basis, sending water that would have been used for agriculture to the reservoir.

Lake Powell’s Levels Projected to Drop Below Critical Threshold

Lake Powell’s water levels are on the cusp of dropping below a critical benchmark and federal officials don’t expect the reservoir’s supply to be replenished until May.

As of Thursday, the lake’s levels were hovering inches above 3,525 feet, which is the threshold local officials set as the “target elevation” while drafting the 2019 Drought Contingency Plan Agreements.

Climate Change, Drought Are Endangering Hydropower Production From Lake Powell. Is It Time to ‘Balance the Water Budget’?

The water level in Lake Powell was at a record low when rain and snow began to fall across the Colorado River Basin in October, soaking dry soils ahead of the winter season.

Water managers, who hoped the trend would build into an above-average snow year that might delay a looming water crisis in the Southwest, watched the snowpack drop to near zero in November. Then, after a massive storm cycle brought six feet of snow to parts of the Rockies around the New Year, they again breathed a sigh of relief.

Dam Providing Power to Millions Nears Critically Low Water Level

A federal dam in Arizona that provides electricity to millions of Americans is at risk this year of running out of the minimum level of water required to generate that power.

Glen Canyon Dam, completed in 1963 and brought online two years later, is at 27 percent capacity, the lowest since it was filled, Bureau of Reclamation Commissioner Camille Touton told the Senate Energy and Natural Resources Committee Tuesday.

Drought Forces West to Turn to Fossil Fuels That Helped Cause It

An unlikely energy sector is emerging as a winner from the West’s megadrought: fossil fuels, whose heavy use has been blamed for creating the conditions causing the drought in the first place.

The drought has slashed the electricity-generating capacity of major hydroelectric dams, forcing buyers to spend millions of dollars to buy extra power from an expensive sellers’ market.
