The use of outboard motors is permitted but not recommended because the channel is frequently too shallow for their use, and the river's heavy silt load may destroy the engine's water pumps after a very brief running time. Fishing for channel catfish, goldeyes and sauger is permitted, but the quantity and quality of these fishes is unpredictable. North Dakota state laws and license requirements apply. Binoculars, cameras, and appropriate field guides will add to your enjoyment, as wildlife and flowers are common along the river. A map of the Little Missouri National Grasslands is available from the park bookstore or from the U.S. Forest Service .
Water levels vary daily.
High water and easy canoeing one day can be a float trip with several portages the next. Wildlife barriers have been installed across the Little Missouri River where it enters and exits the South Unit of the park. A short portage around these fences that block the river are required. Also be aware that, on occasion, river users have reported wires and other temporary fences strung across the river outside of the park boundary. There were no warning signs to let boaters know of these upcoming fences.
