Colorado River Report 9-16-21

Posted on 08 September 2021

September 16, 2021

FLOW: 2090 cfs in Glenwood Springs

WATER CONDITIONS: Low, off-color, and please keep an eye on temps

OVERALL RATING:  2 out 10 

FOOD SOURCES PRESENT: Pale Morning Duns, Caddis, Golden Stoneflies, Midges

THE LOW DOWN: The closures on the Colorado have been lifted, but there are serious concerns for the fish. After almost two months of very muddy water due to mudslides, the fish are in a fragile state. 

Our advice is to fish early, ease off if you've caught a bunch, and perhaps leave the large two-hook streamers behind for another week or two.

Insect hatches have dropped off with all of the sediment in the water, we will update this report after we get out there and see what's happening after leaving this river alone all summer.

Our best guess is that the river will not clear significantly until spring runoff next year, but we shall see.
