Montana is a large and diverse state with myriad water types, including natural lakes and freestone rivers. Reservoirs were created throughout the 1900s for irrigation storage and hydroelectric generation. The waters of Montana support a wide array of both native and non-native fish species.
Trout are the primary game fish species for anglers fly fishing in Montana. Rainbow and Brown Trout were introduced throughout Montana rivers and are widely dispersed today. Brook Trout are common in small, mountain streams and alpine lakes, rarely encountered in the larger rivers.
Mountain Whitefish and Cutthroat Trout are native species and continue to thrive in Montana. A small population of fluvial Arctic Grayling still exists in the upper Big Hole River. Rainbow Trout are native to a small portion of northwest Montana and have adapted well to the rivers across the state.
