The Missouri River is one of the longest rivers in the world. Rising in the Rockies of western Montana, the Missouri flows east and south for over 2000 miles before merging with the Mississippi River north of St. Louis, Missouri. Our focus, as well as most trout fishermen's, is mostly on the 35 mile section below Holter Dam near the towns of Wolf Creek, Craig and Cascade. This tailwater below the dam offers some of the finest fly fishing in the Western US and certainly some of the largest average fish in Montana.
