The Fishery - Pre-Dam
The problem for the river as a fishery was due to the ebbs and flows of the waterflow depending on snowmelt and season. In the spring and early summer, the Bighorn laden with melting snow from the Wind River and Bighorn Mountains, was a torrent that filled the canyon wall to wall and flooded the valley downstream. In the late summer, the river dried up and was a mere trickle.
Few fished the Bighorn, and certainly no one traveled any great distance to try their luck for a few stunted catfish or an occasional deprived sauger.
Below the dam, the change was even more dramatic. A fishery, matching any in the United States was formed by the damming of the river. No longer able to carry its load of mud toward the Gulf of Mexico, the water emerges from the lake crystal clear. The Rainbow and Brown Trout in the river now attract anglers from all over the United States.
Today the Bighorn just below the dam is the most fished river in Montana. During normal water flow years, trout can average upward of 11,000 per mile. A once muddle stream has truly been transformed into a clear water, world class fishery.
Did You Know?
The Crow Reservation may be the largest in the state of Montana at 2.2 million acres, but consider that when first established by treaty in 1851 it was over 38 million acres in size. In relative size it was once larger the current land area of Georgia, today it is about twice the size of Delaware. More...
