The Colorado River originates in Rocky Mountain National Park. We generally fish the sections from Gore Canyon to the town of Rifle bridge. The Colorado is generally a wider and slower river with some faster canyon stretches and excellent hatches and beautiful scenery along the river corridor. The sections below Glenwood Springs are the first to be available in the early season for float fishing. As the spring gives way to summer the focus shifts from Glenwood Springs and Dotsero, upstream to State Bridge and just below Gore Canyon and the Pumphouse boat launch. The Colorado offers more remote stretches of water and a slower pace to the day with an opportunity to view wildlife and unique geology along the way.

Current Conditions:The Colorado River is on the rise, once again. The bump in flows have added some additional color to the river. Fish the slow eddies and focus most of your fishing in these spots. Caddis and mayfies are hatching throughout the day and fish are looking up. Using a double or even triple nymph rig setup is ideal for surveying the water columns for the fish that are not looking up. BWOs, PMDs, and caddis have been the go-to patterns for nymphing. Worms, stonefly and egg patterns are great first or attractor flies. The streamer game right now can be hit or miss, but can produce some bigger fish if you stay committed.
Guide Tip: Nymph with larger flies such as a Pat's Rubberlegs or a worm pattern as the first fly to get into the right zone.
