Welcome to our Bighorn River Fishing Home Page
The Bighorn River is a tributary of the Yellowstone River and it runs approximately 236 miles from the Boysen Reservoir to the Yellowstone River. The Bighorn River is a very popular river for fishing in Montana due to its large numbers of large, wild trout. The cold waters that flow from the Yellowtail Dam helps create one of the better tailwater fisheries for wild trout in the west. Anglers target wild brown trout and rainbow trout in the Bighorn River.
