Large brown trout live in the Dearborn 's deep pools.
The Dearborn river is a rare and unique fishing trip that few anglers will ever get to experience. The river is surrounded by inaccesible land and is only floatable/fishable for a brief, month long, window in the Spring. Some say it is the most beautiful float trip in Montana with it's clear water and towering rock canyon walls. This river is worth the trip for the scenery alone!
