Flow: 382 CFS
Guide Tip of the Week:
They are letting water out of Williams Fork so the flows are up. Flows will be fluctuating, but it has been higher than usual. Look for fish in deeper pools on warmer days the fish might push up into the faster riffles to feed. Tricos are also hatching early morning, so throwing a RS2 behind a heavier nymph is a great option. Midges, tricos, and terrestrials are the main ticket right now. Remember to bring bug spray.
An afternoon voluntary closure is in effect from noon to midnight on the Colorado River from Windy Gap Dam downstream to the Williams Fork confluence. This includes public water at Windy Gap, Hot Sulphur Springs, Byers Canyon, and the CPW State Wildlife Area downstream of Byers Canyon.

The Colorado River between the towns of Kremmling, CO and Parshall, CO offers several public fishing accesses along U.S. Route 40. The river gradient is fairly mellow through out this section, and offers slow runs, gentle riffles, and deeper holes. This water is excellent for both nymph, and dry fly fishing. If you don’t see risers, then fish nymphs. Since this water is a little slower, and shallow in spots, a heavy rig is not usually needed.
