Fly Fishing North Platte River - Fremont Canyon

Fly fishing North Platte Fremont Canyon is a technical and scenic tailwater section of the North Platte River in Central Wyoming, tucked between the granite cliffs below Pathfinder Dam. This narrow canyon flows for a few miles before reaching Alcova Reservoir, and while short, it offers some of the most challenging and rewarding trout fishing in the region. The North Platte here is cold and clear, with deep slots, fast chutes, and slick tailouts — all requiring precise presentation and stealthy approach.

This section is known for its large, wary Rainbow and Brown Trout, often sight-fished with light tippet and small flies. Midges and Blue-Winged Olives dominate the hatch list, especially in early spring and fall, while summer fishing may include terrestrials and occasional Tricos. Fremont Canyon fishes best at lower flows — typically between 50 and 300 CFS — allowing for safe wading and optimal conditions for technical dry fly and nymph fishing. Despite its smaller size, it produces surprisingly large trout that thrive in the deep pockets and oxygenated flows.

With year-round fishable water and easy access from Casper, Fremont Canyon is a favorite for local anglers and traveling fly fishers alike. The canyon is largely public land, with multiple access points, trails, and parking areas near the dam and along the bluff. It’s also one of the best winter fisheries in the state due to regulated tailwater flows and less angling pressure. Whether you're targeting sighted risers or nymphing the seams, Fremont Canyon offers a beautiful, demanding, and highly rewarding fly fishing experience on the North Platte.
