The Colorado River and Fraser River converge near the town of Granby, a central hub for water management and mountain transit in the early 21st century. This 2011 survey illustrates the complex irrigation and storage systems vital to the region, including the Windy Gap Reservoir, the Bunte Highline Ditch, and the Peterson Ditch. Resource management is further evidenced by the Sulphur District Ranger Office and a series of dams, such as the F W Linke Number 2 Dam.
