From the Flattops to the Green River, the Yampa has a long run of it. Starting in the mountains, this river traverses mostly high, dry rangeland and canyons. The flyfishing varies as much as the terrain. The Upper Yampa holds cold-water species whereas warm-water species are found downstream at river’s end. Somewhere in-between, the two meet with opportunity to fish for trout and pike in the same river spot.
