The Colorado River Between the towns of Kremmling, CO and Parshall, CO offers several public fishing access 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.

The Colorado River is transitioning from mid summer hatches into fall hatches. This means Golden Stones, PMDs, Drakes, and Caddis are all still available, but are declining in strength of hatch. Tricos are just starting to hatch, and are an important source of food for trout in the late summer and early fall. Other active aquatic insects of note will be Red Quills, Fall Baetis, and Midges.
The Parshall area on the Colorado River has been active with a large variety of aquatic insects hatching. The current bugs include Golden Stoneflies, Yellow Sallies, PMDs, Green Drakes, and a variety of Caddis. Terrestrial insects are also starting to play a large role in the trouts diet as they move closer to rivers and other consistent bodies of water in order to survive. This makes it a great time of year to fish grass hoppers, beetles, ants, etc., as well as the aquatic insects mentioned above.
The Parshall area on the Colorado River has a good variety of bugs hatching at the moment. We are seeing a few Salmonflies, Golden Stoneflies, Blue Wing Olive Maylfies, Caddis, and Midges hatching throughout the day. A hopper-dropper set up is a good rig to fish at the moment. We suggest a large foamy Salmonfly, or Golden Stonefly dry, followed by one or two nymphs imitating any of the bugs listed above.
It seems that the flows on the Colorado River near Parshall may have peaked out around the 900 CFS mark, and are now back down around 400 CFS. There is a slight stain on the water, but clarity is just about perfect for fishing. We are seeing Baetis, Caddis, and midges hatching currently. Also, Salmonfly nymphs are active along the banks, with reports of a few adults being sighted.
the CFS of the Colorado River near parshall has nearly doubled in the past week mainly due to run off from higher elevations. This means less visibilty, and trout that are feeding less as they figure out new lies in the higher water. The same bugs still apply from the 5/6 update, with more of an emphasis on streamers, eggs, and worms.
Keep in mind that day time temperatures are getting high this next week, and we should start seeing heavier run off from high elevation snow. River flows will rise and some areas may become off color, although the Colorado near Parshall usually maintains decent clarity. Midges and Blue Wing Olive’s have been hatching throughout this section of river, and there has been talk of a few caddis too. Stonefly Nymphs are active as well, providing trout with the opportunity to feed. We have been hooking fish with a medium to light weight nymph rig, consisting of a stonefly anchor, followed by midge, and Blue Wing Olive trailers. We are finding trout holding in a variety of water types, so vary your indicator depth often, and hit all the avaible spots.
