The water is used for irrigation, municipal supply, and hydropower generation. The primary flow constituents are snowmelt from the Rocky Mountains and precipitation. The tunnel diverts water from a number of tributaries, including the Fryingpan River and Hunter Creek. Seasonal trends show peak flow in the spring and early summer, with lower flows in the fall and winter. Interesting facts include the fact that the tunnel was built in the early 1900s and is still in use today, and that it is one of the longest transmountain diversion tunnels in Colorado.
