Construction of Big Bend Dam began in 1959, and Lake Sharpe was named for Merrill Q. Sharpe, the 17th Governor of South Dakota.[3]

Species of fish in the reservoir include walleye, sauger, smallmouth bass, channel catfish, flathead catfish, northern pike, white bass, yellow perch, black crappie, and rainbow trout.[3] Walleye are the primary gamefish in the lake, and gizzard shad are the main food source for the walleye.[4] Big game animals include whitetail and mule deer, elk, bison, coyotes and wild turkeys. Waterfowl and upland game birds include ducks, geese, pheasants, prairie chickens, and grouse.

There is over 80,000 acres of public land and water associated around Lake Sharpe. The South Dakota Department of Game, Fish, and Parks maintains several recreation areas and boat launching facilities around the lake. West Bend Recreation Area and Farm Island State Recreation Area are both located on the lake.[5][6]

The U.S. Army Corps of Engineers maintains recreation areas and wildlife areas near Big Bend Dam, including Left Tailrace Campground.

Much of the western shore of the lake is within the Lower Brule Indian Reservation, while the Crow Creek Indian Reservation lies along the eastern shore.
