About

BLM campground. This area contains two water-oriented recreation sites. Upper Toston Dam campground is located just above Toston Dam on the Missouri River Reservoir, and Lower Toston Dam campground is just below the dam on the free-flowing river. This reach of the river is a popular fishery for rainbow and brown trout. Wildlife frequent the area, and waterfowl, eagles, hawks, cormorants, and pelicans are common sites. Motorboats can be used above the dam on the small reservoir. Lewis and Clark named the canyon below the dam the Gates of the Mountains.
