A #ColoradoRiver Showdown Is Looming. Let The Posturing Begin — KUNC #COriver #aridification #DCP #LakePowellPipeline
From KUNC (Luke Runyon and Lexi Perry):
A showdown is looming on the Colorado River. The river’s existing management guidelines are set to expire in 2026. The states that draw water from it are about to undertake a new round of negotiations over the river’s future, while it’s facing worsening dry conditions due in part to rising temperatures.
That means everyone with an interest in the river’s future — tribes, environmentalists, developers, business groups, recreation advocates — is hoping a new round of talks will bring certainty to existing water supplies and demands.
The table at which those deals will be hammered out is beginning to take shape. The federal government, mostly in the form of the U.S. Bureau of Reclamation, and the seven basin states hold the greatest power in determining what will be up for debate, what will be left out, and whose voices are listened to.
To prepare for the talks, and to coalesce around a set of priorities, leaders in the individual states are attempting to settle their internal issues before coming to that broader negotiating table. We reached out to leaders in three of those states to learn how they’re preparing:
In Utah, all eyes are pointing toward the state’s southwest corner. That’s where the proposed Lake Powell pipeline would transport water from the Colorado River’s second largest reservoir and deposit it near the fast-growing communities of Washington County.
The proposed pipeline is shaping up to be an important bargaining chip in the state’s overall Colorado River negotiation strategy.
Utah’s pursuit of the project has also led the six other states in the watershed — Colorado, Wyoming, New Mexico, Nevada, California and Arizona — to raise serious concerns…
In Arizona, water from the Colorado River enters the Central Arizona Project (CAP) canal, and becomes a ribbon of blue that winds through miles of arid desert to reach the cities of Phoenix and Tucson, where it supplies homes, gardens, businesses, agriculture and golf courses.
Under the 2019 Drought Contingency Plan, Arizona is already taking cuts to its CAP supply. If current projections hold, those cuts will increase nearly three-fold next year, said Ted Cooke, the project’s general manager.
“So 512,000 acre-feet coming out of the CAP supply is about a third — 30% to a third. That’s a lot,” Cooke said.
Arizona could lose a lot more water if the levels in Lake Mead keep dropping. The state’s junior rights mean its Colorado River supply is more vulnerable than others. With drought plans in place now, Arizona is getting good practice at reining in its uses and finding flexibility as supplies shrink, he said…
The Colorado River starts as a modest-sized stream high up in Colorado’s Rocky Mountain National Park. As the river flows through the Southwest, it picks up enough water from its tributaries to supply 40 million people across the seven basin states and Mexico.
About 70% of the river’s flow comes from Colorado’s Western Slope. That fact alone leads water officials in the state to feel protective of the river, said Colorado Water Conservation Board director Becky Mitchell. She also sits on the Upper Colorado River Commission.
“First and foremost, I think it’s important, as Colorado’s commissioner, that we’re looking at protecting our legal entitlement on the Colorado River and protecting our state’s waters for those who depend on it,” Mitchell said.
Leading up to this new round of negotiations, Upper Basin leaders, like Mitchell, have been under pressure to consider implementing what’s referred to as a “demand cap.” In theory, it could be one half of a “Grand Bargain,” a concept that’s been in the Colorado River management ether for years.
Water demands on the river in Colorado, Wyoming, Utah and New Mexico have been flat since the late 1980s. Putting a hard limit on future uses would give water planners throughout the entire basin more certainty, and could appease downstream users from ever issuing a dreaded Compact Call on the river. But Mitchell said that much buzzed-about concept is a non-starter.
