FONTENELLE RESERVOIR
Reservoir Levels • Weather • Hydrology
Fontenelle Reservoir is a man-made lake situated in southwestern Wyoming. It was created in 1958 by the construction of the Fontenelle Dam, which spans the Green River. The reservoir has a capacity of 345,000 acre-feet and provides irrigation and hydroelectric power to the surrounding area. The Green River supplies the reservoir with water, and snowmelt from the nearby Wind River Range contributes to the surface flow. The reservoir is also used for recreational activities such as fishing, boating, and camping. Agriculture is a major user of the water from the reservoir, with crops such as alfalfa, hay, and sugar beets being grown in the surrounding area. The Fontenelle Reservoir is an important source of water for the region and plays a vital role in supporting the local economy.
