Join us... to refresh your spirit on the river!
Sweet Grass County offers two blue ribbon trout streams, The Yellowstone River and The Boulder River, resulting in a fisherman's paradise. Rather you want to use a worm, lure, or fly the fishing opportunities are abundant.
The West Boulder, East Boulder, and the Yellowstone River flow naturally across miles and miles of our land. The Yellowstone River runs east and west. The Boulder River flows from its source in the Absaroka Beartooth Wilderness and joins the Yellowstone just east of Big Timber.
Seven creeks inhabit various sections of the county. Big Timber Creek, Otter Creek, and Sweet Grass Creek come out of the Crazies and flow into the Yellowstone from the north. Upper Deer Creek, Lower Deer Creek, Bridger Creek and Work Creek start in the Absarokas and flow into the Yellowstone from the south.
