River Summary: The Musselshell River is a tributary of the Missouri River that runs through Montana. It has a length of approximately 360 miles, originating in the Crazy Mountains and flowing eastward until it reaches the Missouri River. The river has a rich history, with evidence of Native American settlements dating back thousands of years. Today, the Musselshell River is an important source of irrigation for agricultural purposes, and several reservoirs and dams have been constructed along its course, including the Yellowtail Dam and the Fort Peck Dam. These dams provide hydroelectric power and control flooding along the river. Recreational activities, such as fishing, hunting, and camping, are popular along the Musselshell River, making it an important part of Montana's outdoor recreation economy.
