The mighty Colorado is one of our favorite rivers here at Minturn Anglers, this unbelievable watershed is packed with big views, big rapids, and big fish. from Gore Canyon all the way down to Glenwood Canyon, each stretch of river has something unique and special to offer.
Report Date: April 29th, 2021
Flows have been fluctuating due to reservoir releases, but have remained at good levels. Water temps on the upper sections are still a little on the cold side, so focus on the warmest part of the day when fishing this section. The water isn’t as cold when you get down towards Glenwood, so those sections are fishing good. Clarity and flows can change daily this time of year with the weather, so be prepared for anything. Also, Grizzly Creek access is open after the closure from the Grizzly Creek fire last summer (check the forecast if you plan on using this access as temporary closures are likely if there is rain). Catamount ramp will be closed for most of April for construction, and Radium will be partially closed as well. Please observe seasonal spawning closures around Grizzly Creek, Canyon Creek, and No Name Creek that went into place on 3/15 and go through 5/15 (check CPW regulations for more details).
The main hatches going on right now are still Midges and BWOs on the upper river. The lower river is starting to get some great caddis hatches, which will continue to work their way upstream as the water warms. There will likely be a window for dry fly fishing, but nymphing will definitely be the most productive way to go. The most effective patterns are BWOs and Midges in the 18-20 range. One or two of those behind a larger Leech, Egg, Stonefly, or Worm pattern should get the job done. If the water is off color, don’t hesitate to a bit bigger and brighter with your fly selection. Fish are starting to move around out of the deep holes, so start spending more effort in a little bit faster water where fish are moving to feed, especially on warmer days when bugs are hatching.
Streamer fishing has been getting better, as the fish are starting to become more active as temps and flows rise. Larger articulated patterns are my go-to on the Colorado, but be ready to mix it up if you aren’t getting results.
Please be ethical out there and minimize your fish handling, avoid redds, and don’t fish to spawning fish. Stop by the shop or give us a call for more information!
