Colorado River Report October 4, 2025

FLOW: 1820 CFS below Glenwood Springs

WATER CLARITY: Clear

OVERALL RATING: 10 out of 10

FOOD SOURCES PRESENT: Tricos, Stonefly Nymphs, Blue Winged Olive Nymphs, Caddis,  Midges, Sculpins

THE LOWDOWN: It's a fat fish frenzy out there. Nights have been approaching freezing and the trout are feeling it. 

Trout are gearing up for winter and their feeding patterns reflect that. With the current weather, streamers have been the most entertaining (and sometimes most productive) way to headhunt the giants. If you're looking for numbers, searching the riffles with a stonefly under an indicator has been dredging 'em up. Tricos have also been hatching in numbers up top.

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.
