FLOW: 48.4 cfs below Maroon Creek

WATER CLARITY: Low and Clear

OVERALL RATING: 7 out of 10 

FOOD SOURCES PRESENT:  Yellow Sallies, Caddis, PMDs, Midges, BWOs

THE LOW DOWN: The upper Fork above Basalt is low and clear, and wade-ability is much improved. Caddis, Yellow Sallies, and PMDs are all now hatching all the way up to Aspen on the Roaring Fork.

Small flies like RS2s and Pheasant Tails have been productive behind larger flies such as stones and worms. Stripping a streamer can be fun, too. There is a slight chance that you'll see some late afternoon PMD and midge action on calm and cloudy days also.

OVERALL RATING:  6 out of 10

THE LOW DOWN: Basalt down to Carbondale has been fishing well. Like the upper Fork, lead with a heavy point fly and follow it with something tiny and shiny if you are nymphing.

Local spots like behind Crown Mountain Park and Catherine's Store are good for the wading angler.

OVERALL RATING:  7 out of 10 

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

THE LOW DOWN: The time has come for the mid morning hatches on the lower Fork. Keep an eye out for Yellow Sallies, Pale Morning Duns, Craneflies and Caddis.

While we are very happy to be having a strong monsoon season, several mudslides up the Crystal River have led to frequent blow outs in this section of the river. Check below he confluence with the Crystal and Roaring Fork to see water clarity and conditions before you launch your boat.   

The nymphing game can be strong in the morning leading with large bugs such as Cat Poop Stone Flies or Prince Nymphs. Follow these with a smaller baetis pattern.
