The reservoir was built in 1960 by the U.S. Bureau of Reclamation for the purpose of storing water for irrigation, municipal, and industrial use. The reservoir is fed by snowmelt and surface water runoff from the surrounding mountains, and is also supplemented by the nearby San Juan River. The watershed of the reservoir is approximately 16 square miles, with most of the water coming from the Dolores River. The reservoir is also used for recreational purposes, including fishing, boating, and camping. The area is also known for its winter sports, with nearby ski resorts providing ample snowpack for skiing and snowboarding. The reservoir is an important water source for the surrounding agricultural communities, and supports a variety of crops including hay, alfalfa, and corn.
