The Missouri river at its origin flows through wide-open valleys, flanked by buttes and small mountains that are thinly forested. Grass and agricultural fields line the Missouri River, broken up by cottonwood trees right along the riverbank. Due to the numerous dams and diversions floats on the Missouri River, at least in its upper stretch, can be a difficult. In its lower stretches, particularly above Fort Peck Lake, floats on the Missouri River are unique and well worth the effort. A couple of small sections of the Missouri River offer trout fishing, and the section, between Holter Dam and Cascade, offers great trout fishing.
