The Shoshone Generating Station is a hydroelectric power plant on the Colorado River east of Glenwood Springs, Colorado. In addition to its power output, the water rights the plant uses are among the oldest on the Colorado River, and play a major role in the flow of water to the Western Slope of Colorado. wikipedia 
Shoshone holds water rights to 1,250 cubic feet (35 m3) per second of Colorado River water, which date back to 1902. This predates rights owned by entities on Colorado's Front Range, which draw water from where most of the state's precipitation falls on the Western Slope across the Continental Divide to major population centers east of the Rocky Mountains. By ensuring a consistent flow of water downstream on the river, Shoshone supports diverse sectors of the Western Slope economy, including river recreation, agriculture, and public utility use.
