Colorado River Report

June 19, 2025

FLOW: 4300 CFS below Glenwood Springs

WATER CLARITY: Clear to Hazy

OVERALL RATING: 6 out of 10

FOOD SOURCES PRESENT: Blue winged olive nymphs, emergers and adults, caddis pupae, emergers and adults, Green Drake and PMD nymphs and adults, Sculpins, Midges 

THE LOWDOWN: The water is down and the boats are on! We might not be in the prime of summer yet, but the fishing is picking up down on the big river. 

Big nymphs and dries can still play well while the water is elevated. Guides are leaning towards stonefly and caddis rigs, with the occasional drake pattern thrown in. As always, streamers are a fun addition on overcast days.

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.
