Reservoir Levels Weather Hydrology

Twin Lakes Reservoir is located in Colorado, and it was built in 1978 as a part of the Fryingpan-Arkansas Project. This reservoir serves as a part of the Colorado-Big Thompson Project, which is a water diversion project that serves the Front Range and Eastern Plains of Colorado. The hydrology of Twin Lakes Reservoir is primarily supplied by the melting snowpack in the mountains during the spring and summer months. The surface flow of the reservoir is also supplied by the Arkansas River, which is the primary stream in the area. The reservoir provides water for agricultural and recreational use, and it is a popular destination for fishing, boating, and camping. Additionally, Twin Lakes Reservoir supplies water for the Twin Lakes Tunnel, which diverts water to the Front Range for municipal and industrial use.
