Shoshone generates 14 megawatts of electricity from water that is diverted from the Colorado River to spin its turbines. It then is returned to the main channel. Its 1902 water right ensures that the Colorado flows to — and through — Glenwood Canyon, so its value to Western Slope water users hardly can be overstated. Shoshone “is the primary controlling senior right on the Colorado River,” Colorado River Water Conservation District spokesman Chris Treese said.
Primary control over the water right, however, resides with Shoshone’s owner, Minneapolis-based Xcel Energy. Xcel operates in Denver under a franchise agreement with Denver, whose mayor appoints Denver Water’s board of commissioners. Denver Water depends on the Colorado River to supply its customers, sometimes in conflict with Western Slope water interests. Denver Water and the River District have been engaged in what are termed “global settlement talks” for years about the management of the Colorado River from its headwaters to the Utah state line. The operations of Shoshone “have inevitably arisen” in the global settlement discussions, Treese said.
Western Slope interests are hoping to include Shoshone in the global settlement talks, theorizing that Denver would be willing to influence Xcel to cede some control over Shoshone. Denver in return would get greater certainty about its share of Colorado River water…
Shoshone isn’t for sale, Xcel spokesman Tom Henley said, and if it were, “We wouldn’t be negotiating in the newspapers.” Plus, the Securities and Exchange Commission and Federal Energy Regulatory Commission would have to be involved, Henley said…
Denver, Treese said, “wants long-term certainty of the water it will get from the Western Slope and how much effort it will have to put into getting it.” One way for Denver to gain the assurances it wants could be to aid the River District with its interest in influence on the operations of Shoshone.
Shoshone was shut down from June 2007 to May 2008 when one of the pipes, or penstocks, ruptured. The $12 million repair job included installation of a system that allows for remote operation of the plant. It also gave Western Slope water users a peek into a future without Shoshone, and they didn’t like it. Farmers, ranchers and fruit growers depend on the Colorado River water that passes through Shoshone for their products, and domestic-water providers such as the Clifton Water District depend on it for quantity and quality, he said. “If Shoshone is shut down and the water taken elsewhere, we would greatly miss it,” Proctor said…
The idea of a global settlement includes meeting environmental, recreation and water-quality goals, in addition to accommodating future growth on both sides of the Continental Divide, Lochhead said. Both sides hope to reach a conclusion to the talks soon, within the next couple months, [Jim Lochhead Denver Water Manager] said.
