Prime fishing locations are found throughout the river system. The deep pools and undercut banks in the canyon areas hold large, resident fish. The long, sweeping riffles and gravel runs in the middle valley sections provide excellent nymphing water and consistent action. Confluences with feeder streams are always productive spots, as they create current seams and deeper holes that attract fish. Pocket water around large boulders in the upper sections is ideal for short, accurate casts with dry flies or small streamers.
