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:Parts of the river have opened up near Glenwood and is floatable. The weather is looking great today and into the weekend but expect snow on Sunday and dipping temps. Get out there and fish while its nice. Be careful of ice flows. The upper Colorado River has some solid ice across the river. I would suggest sticking on the Lower Colorado from Glenwood down. Float Fishing is possible from Glenwood down but the action has been slow. Be careful of ice flows and watch the weather. Wade fishing is the preferred way to target fish. Target areas with nice drop-offs on the bank for both nymphing and streamer fishing. The Lower Colorado has been fishing better, but be wary of ice flows coming out of the Roaring Fork when those lows drop below 20. The nymphing had been better in this area than on the upper and there has been a decent amount of bug activity with the occasional fish rising to midges on warmer afternoons.
Guide Tip: Look for that slower, deeper water. If you can find one fish then there will be more in the area!
Hatches: Midges, midges, midges!
