Fishing Reports | Henry’s Fork

Henry's Fork Fishing ReportKnown as the “Graduate School of Fly-Fishing for PH.D. Trout”, the Henry’s Fork of the Snake River is a true gem of western United States fly-fishing. Attempting to catch one of the Railroad Ranch’s well-educated trout can be one of the most satisfying feats in an anglers life. However, there are more facets to the Henry’s Fork than the famous “Railroad Ranch”. In fact, the Henry’s Fork can present any type of water to any anglers. The river below Island Park Reservoir, know as the Box Canyon, provides non-stop tailwater fishing to jumbo rainbows in fast, boulder-churned pocket water. Last Chance and Railroad Ranch areas offers some of the best sight casting to trout in the world. Below Lower Mesa Falls, brown trout join the rainbow trout populations and add to the excitement of the riffles, rapids and pools from the Warm River confluence to Ashton as well as the tailwater sections from Vernon downstream to St. Anthony.

Spring Time – Henrys Fork Fishing Report

Henrys Fork Fishing Report

Henrys Fork Fishing Report – (3.30.21)

Lower River: With the recent warm days and night, the lower Henry’s Fork has been fishing well! Warm River boat access is still a challenge with the snow; however Ashton as well as Ora, Vernon (4X4 only), Chester (Put-In) and Fun Farm are boat accessible. Look for these spring fishing opportunities to stay consistent as our days and nights lengthen and warm. Sporadic dry fly activity is available with BWOs and Midges. The warm calm days have been the best. Nymphing with small rubberlegs, zebra midges, eggs and worms continues to be very productive during the spring months. Streamer fishing has been ok; just keep them low and slow!


Upper river: Flows are now around 430 cfs. Nymphing can always get ’em in the Box this time of year and streamers are rounding out a close second. Look for the Box Canyon to offer some good wade fishing opportunities for the rest of spring. It’s a great place to spend a couple hours now that the river is free of general user traffic.
