Things To Do


Boysen State Park is one of the larger parks in the State Park System. It is a lake-orientated park at the south end of the Owl Creek Mountains at the mouth of Wind River Canyon now part of the Wind River Canyon Scenic Byway. It offers a variety of water type recreation. Day and camping facilities are available. It features interesting geological formations. Several state record fish have been caught out of the reservoir.

Whether it's fishing, boating or just relaxing, you'll find Boysen State Park is a good place to be. The first white men through the Wind River Canyon were the Ashley Fur Party in 1825. The original dam was built by Asmus Boysen in 1908, for whom the park and reservoir are named. Part of the original dam can still be seen adjacent to the tunnels in the Lower Wind River Campground. Mr. Boysen also built a 710kw power plant at the site. Operations ceased when in 1923 a major flood filled the plant with silt. The CB&O Railroad went through the canyon in 1911 and the state highway went through in 1925. The existing dam was completed in 1951. Boysen became a state park in 1956.
