Middle Colorado River

Last update: 04/19/2017 - The water below Gore canyon is on the rise but not fully blown out yet! Clarity should be fair on most days with the best visibility around the edges as of today it is around 1.5 - 2 ft of clarity.. Focus on mid speed runs and riffles, transitional zones, shelves and tight to the bank. Most of the productive fishing will be on a indicator and nymphing rig but if you are fishing out of a boat then a hopper/dropper rig can also be very productive. Salmonfly nymphs are becoming more active and larger (#6/#8) dark pat’s rubber legs are paramount as your lead fly, followed by a sparkle worm/san juan, cased caddis, two bit hooker, soft hackle PT, hare’s ear or zebra midge in sizes #14 - #20. Sporadic caddis and bwo hatches can be encountered so be prepared. Slowly swung or striped dark streamers, such as sculpzilla’s, slumpbuster’s and dirty hippies can also be very effective as the water warms or becomes discolored.

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.


River Access

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. The Trough Road follows the river much of that distance. At several points along the way anglers have access to public stretches of the stream. These spots include Pump House, the 3 miles below Ranch del Rio, state Bridge, Dotsero, and many exits through Glenwood Canyon.

Float Trip Options: there are multiple putin's from Pumphouse downstream to Dotsero.  All the floats vary in length, and the time it takes to do each section will depend on what the flows are at.
