Colorado River Basin (Glenwood Springs)

Water Division 5 is the mainstem of the Colorado River; major tributaries include the Fraser, Blue, Eagle, and Roaring Fork Rivers.   All of Colorado’s major Transmountain Diversion Projects originate in Division 5, including the Grand River Ditch, Colorado-Big Thompson, Moffat Tunnel, Roberts Tunnel, Continental Hoosier System, Homestake Project, Twin Lakes Tunnel, and the Fry-Ark Project.  The major uses of the water resources of the Division, include irrigation, power, recreation, and municipal.  Our staff administer water rights for water users, measure water flow and maintain gaging stations, inspect dams to determine safe water storage levels, and maintain water records within these basins.  Water rights within the basin have yet to be curtailed to meet the provisions of Interstate Compacts, and thus unappropriated water remains available at certain times of the year in specific areas throughout the basin.
