The Madison River Valley, in southwest Montana near the west entrance to Yellowstone National Park, is one of West’s last best places. Trout Unlimited is partnering with the Trust for Public Land to restore flows and protect habitat and open space in the Madison Valley, a critical migration corridor for wildlife and a world-class wild trout fishery. Outfitter and Sun Ranch manager Craig Mathews explains how the partnership is keeping the river and its tributaries healthy and protecting the valley from overdevelopment.
