About Stillwater River
The Stillwater River, a beautiful and wild Montana river, offers a dynamic fly fishing experience across its 70-mile length, transitioning from the Absaroka-Beartooth Wilderness to rolling prairie and canyons. Anglers will find healthy populations of rainbow, brook, cutthroat, and brown trout, with larger brown trout exceeding twenty inches found below the town of Nye. Key insect hatches include Caddis and Hoppers, providing excellent dry fly opportunities. While the upper wilderness sections present significant whitewater and are challenging to float, the river boasts abundant wading access, particularly in the lower canyon and prairie regions where trout numbers are high. Expect pocket water fishing in the upper reaches and opportunities for streamer and nymph fishing for larger brown trout downstream.
