About Our Site - Boysen State Park

 

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 on 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.

FOR IMMEDIATE RELEASE

            A series of Star Gazing and Solar Viewing programs beginning August 18 are featured at Boysen State Park during the Great American Eclipse weekend.

            All of the programs will take place at the Tough Creek Campground and Lakeside Area.

            In addition to the special programming, Boysen State Park will prove to be a prime viewing area of the Eclipse since it is located in the “Area of Totality.” Also, Boysen State Park is an area void of light pollution enhancing the viewing of the Eclipse.

Visitors to Boysen State Park are encouraged to come to the park early as the first-come, first-serve campgrounds will fill up quickly. Day Use areas will be available for Eclipse viewing.
