#Wyoming looks to store, divert more #water as #LakePowell dries up — Wyofile.com #GreenRiver #ColoradoRiver #COriver #aridification

Lake Powell is seen in a November 2019 aerial photo from the nonprofit EcoFlight. Keeping enough water in the reservoir to support downstream users in Arizona, Nevada and California is complicated by climate change, as well as projections that the upper basin states of Colorado, Utah, Wyoming and New Mexico will use as much as 40% more water than current demand. A recent white paper from a lineup of river experts calls those use projections into question.

From Wyofile.com (Angus M. Thuermer Jr.):

As Lake Powell dropped to its lowest-ever level [July 23, 2021] — a decline that has forced dam tenders to unexpectedly release 125,000 acre-feet of water from Flaming Gorge Reservoir — Wyoming stood behind five projects that could divert tens of thousands more acre-feet from waterways in the troubled Colorado River Basin.

Powell’s surface elevation dipped to 3,555.09, lower by 12 hundredths of an inch than the previous post-completion nadir of April 8, 2005. The new benchmark is “probably worth noting,” Wayne Pullan, the U.S. Bureau of Reclamation’s Region 7 director, said in a press call [July 27, 2021].

“The fact that we’ve reached this new record underscores the difficult situation that we’re in,” he said…

Friday’s mark amounts to a 150-foot drop in the storied Utah-Arizona reservoir over 24 years, a decline that’s spurred action to preserve irrigation flows, millions of dollars in hydropower revenue and myriad necessities for 40 million people in the West.

As the BOR began its “emergency” release of 125,000 acre-feet from Flaming Gorge Reservoir on July 15, a coalition of downstream water users called for a moratorium on new dams and pipelines…

In an era of drought, aridification and climate change, new water projects will be closely scrutinized, Pullan said…

Meantime Gov. Mark Gordon announced he will appoint a drought working group to ensure “local perspectives on issues that impact our water users and the State” are heard when planning for a crisis that “may last for years.”

Wyoming will not be deterred from its water development goals that would store, divert or otherwise use another 115,000 acre-feet in the upper reaches of the 246,000-square-mile Colorado River system, top officials told WyoFile.

“A pure, strict moratorium flies in the face of rights held by all seven [Colorado River Compact] states,” said Pat Tyrrell, Wyoming’s member on the Upper Colorado River Commission. “I would have a hard time recommending that Wyoming get itself in that position.”

The Bureau of Reclamation has a limited say in what Wyoming can do with its water and development, state Senior Assistant Attorney General Chris Brown said.

“They certainly don’t get to say ‘no,’” he said. “They certainly don’t have that authority in Wyoming to decide how Wyoming wants to develop its water.”
