GALLATIN RIVER
For many anglers who are visiting the West for the first time, the Gallatin River typifies their idea of western rivers. This is especially true if they view the river for the first time in the canyon stretch along US 191. The Gallatin River in this section is a brawling, moderate size, freestone, mountain stream. From its headwaters in Yellowstone National Park to where it joins with the Madison and Jefferson Rivers at Headwaters State Park near Three Forks, Montana to form the mighty Missouri River, the Gallatin is 105 miles in length. Much of the river is easily accessible to anglers as US 191 runs right along the river over much of its course.
