About the little missouri river

The Little Missouri River is a tributary of the Missouri River that stretches 560 miles through Wyoming, South Dakota, and North Dakota. The river was named by French trappers who explored the region in the 18th century. The river's hydrology is characterized by a wide range of flow rates, from low during dry periods to intense flash flooding during rainy seasons. The Carter Lake Dam in Wyoming and a series of four dams in North Dakota, including the Theodore Roosevelt Dam, manage the river's flow for agricultural and recreational purposes. The river's scenic beauty and diverse wildlife attract tourists for activities like fishing, camping, and hiking. The Little Missouri River is also a source of irrigation for crops such as wheat and soybeans.
