Boysen State Park

Boysen State Park is a large protected area at the south end of the Owl Creek Mountains, dominated by an artificial reservoir that shapes its landscape. The grounds span wide terrain and feature both open water and tight canyons that channel the Wind River through dramatic rock formations.

The original dam was built in 1908 and later replaced by a modern structure completed in 1951. The park itself was established in 1956 and named as a memorial to the engineer who created the first dam.

The park preserves Native American territories where generations of tribes lived along the Wind River, maintaining connections to their ancestral lands.

The park provides multiple campgrounds, boat ramps for anglers, and a marina facility for exploring the water. Visitors should know that conditions vary greatly by season and water levels can shift noticeably throughout the year.

The Wind River flows northward through the park, which is unusual for rivers in North America. This flow direction makes this waterway a distinctive geographic feature compared to most other major rivers in the region.
