The Little Bighorn and South Tongue rivers were historically high-quality trout streams with vast numbers of rainbows, browns, brookies and Yellowstone cutthroat. However, their fish populations were cast into jeopardy when grazing cattle damaged delicate streambanks, causing siltation that reduced oxygen levels and filled deep pools. Your support is in part responsible for returning these fisheries back to their glory. Once the cattle were prevented from reaching the rivers, eroded shorelines were replanted and stabilized with rock. Workers and volunteers then created new pools at 40 sites on the Little Bighorn and at nearly 50 locations on the South Tongue. These changes provided the necessary habitat to encourage natural reproductions of wild brown and brook trout.
