Boysen State Park is surrounded by the Wind River Indian Reservation and offers both day-use and overnight camping facilities. Boysen Reservoir is well-known as one of Wyoming’s best walleye and trout fisheries. During most of the season, the reservoir is warm enough for all water sports and an easily accessible swimming beach is located on the east shore. Water skiing is a popular sport here.

A wide range of fish is present, including walleye, sauger, perch, crappie, ling, rainbow, cutthroat and brown trout, largemouth bass, bluegill, stonecat, black bullhead, mountain whitefish, lake trout, brook trout and splake. Non-game species include carp, fathead minnow, plains killifish, golden and sand shiners; flathead, lake and creek chubs; white, longnose and northern redhorse suckers; and the river carpsucker.
