The first white men through the Wind River Canyon where the wind river flows North, built the original dam in 1908 from whom the park and the reservoir are named Boysen State Park. The CB and O Railroad went through the canyon in 1911 and the state highway went through in 1925. In 1923 a flood filled the power plant with silt and thus operations ceased. The existing dam was completed in 1951 and Boysen became a state park in 1956. Very pretty setting but primitive camping with pit toilets; that is why they probably called it the Tough Creek Campground. In fact, we were the only ones camping there for the night and the ranger did hunt us down for the $17.00 camping fee. Come to find out All of Wyoming State Parks are Primitive Camping. We were surrounded by the reservoir on two sides and we could smell that old algae smell from the water. Thankfully it was cool out and we really did not need a swim. We did make a fire and got a good nights rest since it was so peaceful in the middle of nowhere!!!! Keep heading west we told ourselves so we set out to drive wherever the motorhome took us as long as we were going westward.
