Tongue River Reservoir State Park, Montana

Located in the Teton Valley, Tongue River Reservoir State Park surrounds a man-made reservoir created when the Tongue River Dam was completed in 1948.

The dam was originally built to provide water for irrigation for agricultural purposes and to supply water for stock watering needs, but now offers visitors the opportunity to go boating, fishing, and enjoy other recreational activities.

The reservoir contains fish species such as walleye, rainbow trout, northern pike, smallmouth bass, whitefish, and yellow perch, and attracts anglers from throughout the region.

Fishing access sites for shore anglers are available, and there are several boat ramps for those who want to use a canoe or kayak.

Many visitors come specifically for wildlife viewing, but if you choose to come from March through December, be sure to bring bear spray. It is not uncommon to see grizzly and black bears in the park, especially in the spring when they have come out of hibernation. There are also plenty of other land animals to see like elk, moose, deer, bighorn sheep, and pronghorn antelope.

Though it’s located in southern Montana, the closest city – about 30 miles away – is Sheridan, Wyoming. If you’re planning a visit to Tongue River Reservoir, you’ll likely want to stop in town at some point for groceries, gas, or to stay overnight.

If you’re planning on continuing your trip, Sheridan offers convenient access to the Bighorn National Forest.
