Also, after the channel is ice free early in the season, it is common to have large heaps of mud-covered ice slabs lining the shores. 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.
Water levels vary daily.
High water and easy canoeing one day can be a float trip with several portages the next. A wildlife barrier has been installed across the Little Missouri River where it exits the National Park. A short portage around this floating fence that blocks the river exit is required.
