Big Thompson River Professional Guide

Detailed Trail Description from our Guidebook

"From high in Rocky Mountain National Park in north central Colorado, the Big Thompson flows east through a canyon to the town of Loveland and eventually into the plains, where it meets the South Platte near Greeley. Starting small, the Big Thompson becomes a medium-sized meadow river after it leaves the heavily fished Lake Estes (in the town of Estes Park) and Big Thompson Canyon. The river is subject to low flows and ice during the winter months, which makes fishing tough or sometimes impossible.

There’s some fantastic dry fly fishing, however, starting in spring and continuing to early fall Types of Fish: Stocked rainbow, cutthroat, and wild brown trout. There are also naturally reproducing browns and rainbows. Fish average 6-14 inches.This eTrail covers the "where, when, and how" to fish in this region. You'll get a full-page map and information on the known hatches, suggested equipment to bring, and the best flies to use."
