America's 100 Best Trout Streams

If it's possible for a big river in Montana to be underrated, the Mo is it. The tailwater sections from Wolf Creek on down are, quite simply, some of the best fly-fishing waters in the world. If Montana had only the Mo, it'd still be worth a journey. Long banks, big bends, backwaters, braids, canyon walls, rip rap - this river has it all. It's been hammered by whirling disease and in the last few years the water levels have been uncomfortably low from late July on, but still very fishable. Big fish on little nymphs in March, and hammerhead hits on streamers. The only reason I didn't rate it five stars is the crowds in the summertime, much worse than the Yellowstone, when the hoppers are flying.
