General Information

Description - The impounded Tongue River provides a 12-mile long reservoir set in the scenic red shale and juniper canyons and open prairies of southeastern Montana. Large bodies of water such as this are rare in this prairie country, and 50,000 visitors flock each year to enjoy the recreational opportunities. Boating and other water sports are popular here, and the park boasts excellent bass, crappie, walleye, and northern pike fishing. Four state record fish have been pulled from its waters. The park is 640 acres in size at an elevation of 3,454 feet. The site has vault toilets, boat rental, public phone, groceries, LP gas refill, grills/fire rings, picnic tables, trash cans, and drinking water (5/30 - 9/1).
