Fly Fishing the Williams Fork River

A small, technical tailwater flowing cold and clear from Williams Fork Reservoir through the Arapaho National Forest to the Colorado River near Parshall, the Williams Fork rewards patient anglers with wild brown and rainbow trout in a quiet, off-the-beaten-track setting that rarely sees the crowds of Colorado's more famous tailwaters.
