Current River Flow Updates

Latest update: 4/3/2020 -- The river has cleared of ice! Flows are 682 at Kremmling, 781 at Catamount and 1154 at Dotsero and water temps have been rising. Seeing temps nearing 50. This usually means good fishing. Look for that magic 56 degree temp. You could start seeing some color in the water but this should make the fishing good. So let the float and wade fishing begin. This time of year, look for fish in the deeper pools, runs and holes. Really get those flies down. Try- stonefly patters, worms, egg patterns, big larvae, Chironocones, Zebra Midges, smaller mayfly and caddis patterns, and baetis and midge patterns.

River Information

This stretch of the Colorado is a very popular area for anglers to frequent, and for good reasons. We consider the Middle Colorado to be from the town of Dotsero, up through the Gore Canyon. This stretch offers anglers a good variety of waters to fish and also includes some float fishing options. The Pumphouse access is certainly a favorite location of many and parking here and hiking up into the Gore Canyon can be a great way to spend the day- particularly when the Salmonfly hatch is going. The river is fairly good sized here and wading anglers will, for the most part, be relegated to the bank. In true freestone fashion, this stretch of river offers anglers a wide variety of ways to catch its Rainbow, Brown trout and Rocky Mountain Whitefish.

Seasonal Conditions

The middle portion of the Colorado is fishable year round and many of the same tactics used on the lower river will work here as wellt. Like most rivers around the state, Spring through Fall will be most productive when the wide variety of aquatic insects that live here are most active. Stoneflies are a major part of a trout’s diet and the river sees some terrific dry fly fishing in mid-summer with Golden Stoneflies and the ever popular Salmonflies. Caddis and a smattering of mayflies will typically be found throughout the summer as well. The colder months will primarily be a nymphing game. Fishing the slower, deep pockets very thoroughly and diligently will be productive through the winter. Considering the size of fish swimming in this stretch, spending a little time throwing a streamer will always be worth a try as well.

The Colorado runs beneath State Highway 9 between Grand County Road 1 and Kremmling. A mile south of Kremmling, CR 1 also known as the Trough Road, heads west to State Bridge, about 25 miles away.
