In addition to being a great fishery, the Green River has a rich history in that it was on the banks of the Upper Green where many of the mountain man fur trading rendezvous events took place in the early 1800s. The Green River can be enjoyed by the beginner and intermediate fisherman, but can also provide a great challenge for the more advanced fishers. The green has an abundant population of Rainbows from 10 to 16 inches, but the possibilities of catching Rainbows over 20 inches are very common. Browns of 14 to 18 inches are frequently caught, and here again lunkers over 20 inches are available. The Green is also home to Cutthroat and Brook trout.
