Colorado River Basin including out of basin demands — Graphic/USBR
From the Glenwood Springs Post Independent (John Stroud):
…it’s important to note that “nobody is digging a new tunnel tomorrow,” and organizations like the Glenwood Springs-based River District are active at the table in working to protect Western Colorado interests in the face of growing Front Range water needs, [Jim Pokrandt] said.
“There are a lot of top-10 lists when it comes to rivers and water conservation,” Pokrandt said in reaction to the listing last Wednesday by the nonprofit conservation group American Rivers. “It’s a good way to generate publicity for these various causes.”
American Rivers calls on Colorado Gov. John Hickenlooper to prevent new water diversions and instead prioritize protection of Western Slope rivers and water conservation measures in the Colorado Water Plan, which remains in discussions through a roundtable process that involves stakeholders from across the state.
Already, about 450,000 to 600,000 acre-feet of water per year is diverted from the Colorado basin to the Front Range, Pokrandt noted.
The prospect of more diversions “is definitely being advocated in some quarters from those who say a new project is not a question of if, but when and how soon,” he said.
“We’re saying that’s a big ‘if,’ because there are a lot of big issues around that.”
Pokrandt said any new trans-mountain diversions are “questionable, if it’s even possible.” That’s primarily because of the Colorado River Compact with down-river states that guarantees their share of river water.
“It’s important that we don’t overdevelop the river, and any more transmountain diversions should be the last option out of the box [for Front Range needs],” said. “First and foremost, it behooves all of Colorado to be more efficient in our water use.”[...]
Pokrandt notes that many municipalities across the state, not just the Front Range, are scrambling to find water to take care of projected population growth. That means more water demand on both sides of the Continental Divide.
“But there’s a big question about how much water is really left to develop,” he said. “There’s also an economic benefit to leaving water in the river without developing it, so there’s that issue as well.”[...]
Another Colorado river on the American Rivers endangered list this year is the White River, which was No. 7 due to the threat of oil and gas development and the risk to fish and wildlife habitat, clean water and recreation opportunities.
The White River flows from the northern reaches of the Flat Tops through Rio Blanco County and into the Green River in northeastern Utah.
“Major decisions this year will determine whether we can safeguard the White River’s unique wild values for future generations,” said Matt Rice of American Rivers in their Wednesday news release.
From the Vail Daily (Melanie Wong):
The conservation group American Rivers releases the annual list, and rivers that are threatened include sections of the Colorado that run through Eagle County, including headwater rivers, which include the Eagle River.
According to the group, the river is threatened as many Front Range cities look for future water sources to meet growing municipal and industrial needs. Some of those communities are eyeing various parts of the Colorado for diversion.
Advocates hope the list garners some national awareness and spurs lawmakers to prevent new water diversions and prioritize river protection and water conservation measures in the state water plan.
“The America’s Most Endangered Rivers report is a call to action to save rivers that are at a critical tipping point,” said Ken Neubecker, of American Rivers. “We cannot afford more outdated, expensive and harmful water development schemes that drain and divert rivers and streams across the Upper Colorado Basin. If we want these rivers to continue to support fish, wildlife, agriculture and a multi-billion dollar tourism industry, we must ensure the rivers have enough water.”[...]
For decades, Front Range growth has been fed by Western Slope rivers. Around a half million acres of water is already being diverted east from the Upper Colorado and growing cities need more. The problem with diversions, said Neubecker, is that the water leaves the Western Slope forever, citing a proposed project to tap into Summit County’s Blue Mountain Reservoir and divert water from the Blue River.
“Grand and Summit counties are justifiably worried about a Green Mountain pumpback, and so should Eagle County, because that project isn’t possible without a Wolcott reservoir,” he said. “With water diverted to the Front Range, we never see it again. It has serious impacts on us as far as drought and growth. It’s a finite resource.”
Historically, there have been agreements that have benefited both the Western and Eastern slopes, and river advocates said they want to see more such projects. The Colorado Cooperative Agreement, announced in 2011, involved the cooperation of many Eagle County entities. The Eagle River Memorandum of Understanding, signed in 1998, was also a major victory for mountain communities, significantly capping the amount of water that could be taken at the Homestake Reservoir and keeping some water in Eagle County.
Another settlement with Denver Water in 2007 was a big win for the local water community, said Diane Johnson, of Eagle River Water and Sanitation. “Denver Water gave up a huge amount of water rights, pretty much everything leading into Gore Creek, and as for a Wolcott Reservoir, it could only be developed with local entities in control,” she said. “Things are done more collaboratively now. It’s not the 1960s and ’70s anymore, where the Front Range developed the rivers without thought of how it affected local communities.”[...]
A new Colorado State University report commissioned by the Eagle River Watershed Council studied the state of the Eagle River.
“It’s clearly showing that the biggest threat to this portion of the Upper Colorado is reduced flows. It’s impacting wildlife for sure, most notably the fish,” said the council’s executive director Holly Loff.
With less water, the average river temperature is rising, and many cold-water fish have either been pushed out or killed as a result. Less water also means less riparian (riverside) habitat, an ecosystem that supports 250 species of animals. Of course, less water also affects river recreation and means there’s less water to drink.
