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 Salmonfly hatch has come and gone for the most part on the upper stretches of the Colorado River, although you may still see a few adults lingering near the banks. Next years hatch is always in the water waiting in nymph form, so never count out this food source, even when the hatch is done.
We are seeing river flows rise as the upper elevation run-off starts to take effect, as result water clarity has been low on some days. However the loose dirt is starting to get flushed out of the feeder drainages and water clarity is becoming more consistent. We are experiencing about 1’ - 2’ of clarity most days, which is great for fishing. A hopper-dropper, or nymph rig is the go to set up at the moment. We have been fishing imitations of adolescent Salmonfly Nymphs, Giant Golden Stoneflies, Yellow Sallies, Caddis, Baetis, midges, and worms.
The Colorado River near Parshall has been fishing fair. The water clarity has been varying between about 1-2 feet of visibility. This cold front should also help improve water clarity and we should be seeing about 2 feet or so of vis. until the weather pattern changes. Stonefly nymphs, Baetis, and midges are still the most available food sources. A few Caddis have been hatching as well, but not in large numbers yet so concentrate on fishing the larva stage vs the pupa. Eggs, worms, and streamers have also been cathcing fish on more stained up days.
The Colorado River near Parshall has been fishing well with action being had on both nymphs and dry flies. Stonefly, Baetis, Midge, and Caddis Larva have all been hooking fish. Some days have been seeing plentiful midge hatches, along with a few blue wing olives here and there. During these times dry patterns can be effective if fish are activley rising. It is starting to be spring spawn season so eggs can hook fish as well, or consider throwing some streamers if you are in the mood.
