Gallatin River Montana: Flows, Fishing, Floating

Gallatin River Montana – The river has an incredible dynamic. It starts as a small stream around the Yellowstone National Park border and quickly gains volume as it passes Big Sky and enters the Gallatin Canyon. The canyon is a fast stretch with whitewater opportunities in high flows and great fishing throughout the spring, summer and fall.

Access is excellent until it gets closer to Gateway and private lands begin dominating the landscape. Even in this lower river area, you can utilize public access while remaining below the high water mark.
