One of Wyoming’s premier parks is Boysen State Park. It is located north of Shoshoni and south of Thermopolis at the south entrance to the Wind River Canyon. Beautiful area.
This is not the best State park for general camping and hiking, however, if you are a water sport enthusiast, it is wonderful. The reservoir has 76 miles of shoreline with numerous camping areas and boat ramps. Bring your motor boat, fishing boat or jet ski and have a blast. While you are here, you can visit the town of Thermopolis for food, drink and the hot springs…https://wyadventures.com/thermopolis-hot-springs-state-park/.
The Dam
The original Boysen Dam was built in 1908 by Asmus Boysen, hence the name. Part of it can still be seen next to the tunnels entering the Wind River Canyon. He also built a 710 kW power plant, but that went out of business in 1923 after a flood filled it with silt. The existing Dam was built in 1951 and the area became a state park in 1956.
Fishing
The fishing is great with a ton of diversity. Fisherman can count a shot at sauger, perch, crappie, walleye, cutthroat, rainbow and brown trout and a whole lot more.
Camping
As far as camping goes, there is a variety. There are eleven campgrounds all the way around the reservoir, a day use area and a marina on the north end. Fishing licenses and snacks are available at the marina during the warmer months- May through October.
