Frequently Asked Questions

What is the best river for brown trout in the US?
Montana's Bighorn River and Missouri River are the top brown trout rivers in the West. Both offer 3,000+ trout per mile with browns regularly exceeding 20 inches. Colorado's Gunnison Gorge and Oregon's Owyhee River offer the best trophy brown trout potential for fish over 24 inches.
What is the best time to fish for brown trout?
Fall (September-November) is prime time for large brown trout, as they become aggressive before and during the spawn. Streamer fishing in fall produces the biggest browns of the year. Spring and summer offer excellent dry fly and nymph opportunities on most western rivers.
What flies work best for brown trout?
Streamers like the Sex Dungeon and Woolly Bugger are most productive for trophy browns, especially in fall. For everyday fishing, the Pheasant Tail Nymph, Zebra Midge, and Parachute Adams are reliable producers. Brown trout tend to be more selective than rainbows, so matching the hatch matters.
