The Yellowstone River is a major tributary of the Missouri River, spanning 692 miles from its source in Wyoming to its mouth in North Dakota. The river played a significant role in the history of the American West, including the Lewis and Clark expedition. It also served as a major transportation route for fur traders and settlers. The river is fed by snowmelt and precipitation, with the highest flows occurring in the spring and early summer. The river has several reservoirs, including the Buffalo Bill, Yellowtail, and Fort Peck dams. These provide hydroelectric power, irrigation, and flood control. Recreational activities, such as fishing, boating, and camping, are popular along the river. The river also supports agricultural activities, including cattle grazing and crop irrigation.
