Head east from Glenwood Springs in western Colorado today, and you’ll encounter an isolated stretch of I-70 hugging the curves of the Colorado River. But 110 years ago, you would’ve hit “a thriving little city” of hundreds of people living in tents, nestled there between the high walls of the river canyon so its residents could build a hydroelectric plant. That facility, the Shoshone power plant, still adds energy to the grid, but its true importance lies elsewhere: Shoshone is a cornerstone of the elaborate complex of water rights, laws, agreements and relationships that shape the management of the upper Colorado River. Because of the water rights it holds — and because it returns the water it uses to the river channel — the diminutive plant dictates how the river is managed in Colorado. “It’s an interesting historic relic with huge implications for the ecological health of the river,” says Brent Uilenberg, a manager in the U.S. Bureau of Reclamation’s Upper Colorado Region, “and (for) providing a reliable water supply for East and West Slope human uses.” To view the full article visit High Country News.
