The Redwater River is a 135-mile-long tributary of the Missouri River in eastern Montana. The river is named for the red clay that lines its banks. Historically, the river was used by Native American tribes for transportation, hunting, and fishing. The river is fed by several smaller streams and has a variable flow due to seasonal precipitation patterns. The Fort Peck Dam and Reservoir on the Missouri River is the largest reservoir in the area and has a significant impact on the flow of the Redwater River. The river is used for irrigation and supports agricultural activities in the area. Recreational use of the river includes fishing for trout, walleye, and catfish, as well as hunting and camping in the surrounding area.
