For shear beauty and the number of fish per mile, the Green River below Flaming Gorge is hard to beat. The last electroshock they did showed something in the neighborhood of 14,000 fish per mile. Near the dam you'll find Rainbows, Cutthroat and Cutbows. As you drop down stream the Browns become more prevalent. The area around Little Hole and down stream is great Wet Fly/Soft Hackle water and you can catch fish all day long without moving more than a couple of hundred yards.
