The Redwater River flows through the Hi-Line prairie country of northeastern Montana near Wolf Point before joining the Missouri River. This warmwater stream holds populations of channel catfish, northern pike, smallmouth bass, and sauger in its lower reaches. The river provides a different fishing experience from Montana's famous trout streams, offering prairie fishing for warmwater species. Spring and early summer provide the best fishing before summer heat warms the water. Catfish action can be excellent in the lower river near the Missouri confluence. Access is limited through much of the drainage, with most fishing occurring at bridge crossings and near the mouth. The remote northeastern Montana landscape offers solitude and a glimpse into prairie river ecosystems. The Redwater River is worth exploring for anglers interested in warmwater species and off-the-beaten-path Montana fishing experiences.
