Boysen State Park

Boysen State Park enjoys the distinction of being one of the largest state parks. It has an impressive lake, which is the main attraction. The park also has interesting land formations, the result of geological events dating back thousands of years. Located south of Owl Creek Mountains, the park is at the entrance of Wind River Canyon, part of Wind River Canyon Scenic Byway. Although open year round, limited services are offered during the winter season.


Surrounded by Wind River Indian Reservation, Boysen State Park has camping and water sport facilities.

The most popular sport may well be fishing because the region is famous for its trout and walleye fishing, but most water sports, including skiing, can be found here because the reservoir has warm water during most of the season. Additionally, the east shore has a beach for swimming.

Besides camping and water sports, visitors also come to Boysen State Park for picnics and sightseeing along the 76 mile shoreline. There are also several scenic regions along Wind River below the dam.

The northern shore of the lake has a marina and concession stands. Fishermen can purchase their fishing licenses here, as well as food and bait. Although most of the fishing takes place in summer, fishing also continues in winter, and the lake is considered a first-rate place for ice fishing. State record fish have been caught here.

The lake offers numerous fishing opportunities.

Fish commonly caught include:
• Walleye
• Sauger
• Perch
• Crappie
• Ling
• Rainbow
• Cutthroat
• Brown Trout
• Largemouth bass
• Bluegill
• Stonecat
• Black Bullhead
• Mountain Whitefish
• Lake trout and Brook trout
• Splake

Non-game species can also be found here, including:
• Carp
• Fathead Minnow
• Plains Killifish
• Golden and Sand Shiners
• Flathead, Lake and Creek Chubs
• White, Longnose and Northern Redhorse Suckers
• The River Carpsucker.
