Green Mountain Reservoir is a man-made lake located in Summit County, Colorado. It was constructed in 1942 as part of the Colorado River Storage Project and is owned and operated by the Bureau of Reclamation. The reservoir has a capacity of 106,000 acre-feet and is primarily used for irrigation and recreation. The water source of the reservoir is mainly from the Blue River and is supplemented by the snowmelt from surrounding mountains. The reservoir also receives water from the Dillon Reservoir through the Lower Blue River. The water is used for irrigation of farmland in the surrounding area and for recreational activities such as fishing, boating, and camping. The reservoir plays a critical role in the hydrology of the Blue River Basin and provides a significant source of water for the agriculture industry in the region.
