Colorado River Report

September 20, 2024

FLOW: 2220CFS below Glenwood Springs

OVERALL RATING: 8 out of 10

FOOD SOURCES PRESENT: Pale Morning Duns, PMD Rusty Spinners, Craneflies, Caddis, Golden Stoneflies, Hoppers and Terrestrials, Blue Winged Olives, Sculpins, Midges 

THE LOWDOWN: Water levels have held remarkably steady the last couple of weeks, which is great news for those pre-spawn browns looking to stuff their gullets, and for the fishermen looking to target them. Cooler weather has also helped keep the water temps in check and long days on the boats more pleasant.

Most of you know that cloudy days are best, especially for a slow-release hatch. The Colorado is a big, brawling river- ideal for a drift boat but it can be accessed on foot. This river is a bit more of a quality than a quantity fishery, so be prepared to hook onto some pissed-off fish that will dump your reel in a few seconds.

Wade-fishers should exercise caution in the biggest river of the valley, but popular wading spots include the confluence with the Roaring Fork, Dino Boat ramp (both above and below the ramp) and upstream of South Canyon rapid.
