Reservoir Levels Weather Hydrology


Big Sandy Reservoir is a man-made reservoir located in Sweetwater County, Wyoming. The reservoir was built in 1963 as part of the Seedskadee Project, which was a joint effort by the Bureau of Reclamation and the state of Wyoming to provide irrigation water to the Green River Valley. The reservoir covers an area of 2,500 acres and has a storage capacity of 40,000 acre-feet. The hydrology of the reservoir is primarily dependent on snowmelt and surface water from the Big Sandy River and Bull Lake Creek. The reservoir is used for agricultural irrigation, recreation, and wildlife habitat. It is a popular destination for camping, fishing, and boating, and is home to a variety of fish species including rainbow trout, brown trout, and kokanee salmon.
