The Milk River flows across Montana's Hi-Line region through the northern prairies, originating in Glacier National Park and meandering over 700 miles before joining the Missouri River near Glasgow. Named by Lewis and Clark for its milky appearance from glacial sediment, this prairie river offers warmwater fishing for walleye, sauger, northern pike, channel catfish, and smallmouth bass. The lower river below Fresno Dam provides the best fishing opportunities, with spring and fall being prime seasons before summer heat and low flows reduce water quality. While not a trout destination, the Milk River serves as an important recreational fishery for northeastern Montana communities and provides a distinctly different angling experience than the state's mountain streams. Several FWP access sites along the river's course provide public entry points for boat and bank anglers exploring this remote prairie waterway.
