Roaring Fork River Report August 10, 2021

UPPER ROARING FORK- ASPEN DOWNSTREAM TO BASALT   

FLOW: 285 cfs below Maroon Creek

WATER CLARITY: Low and Clear

OVERALL RATING: 7 out of 10 

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

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

The green drake hatch is early this year, and we are seeing them mid-day as well as at twilight, from Aspen all the way down Basalt. Fish the softer seams adjacent to quicker moving water and drakes seem to love a gravelly bottom.

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.

HATCHES: Green Drakes 10-12, Caddis 16-20, Golden Stoneflies 8-10, PMDs 16-18, Yellow Sallies 14-16, Midges 20-24

STREAMERS: Autumn Splendor 6, Zuddler 6, Slumpies 6-8 

HINTS: Fish the soft water where your flies have time to get down in front  of the fish.

MIDDLE ROARING FORK- BASALT DOWNSTREAM TO CARBONDALE 

FLOW: 384 cfs in Basalt, the runoff has ended and flows are dropping quick

WATER CONDITIONS: Clean and clear

OVERALL RATING:  6 out of 10

FOOD SOURCES PRESENT: Green Drakes, Caddis, Yellow Sallies, PMDs, Midges

THE LOW DOWN: The Green Drake hatch came early and for the most part has moved upstream already. With decreased flows, we are seeing just as many hatch mid-day as we are at twilight. It seems like many hatches are on fast-forward this year.

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.

LOWER ROARING FORK- CARBONDALE TO GLENWOOD 

FLOW: 557 cfs in Glenwood Springs 

WATER CONDITIONS: Low and clear on days with no rain, muddy and blown on days with rain. Keep an eye on the water temperatures.

OVERALL RATING:  6 out of 10 

FOOD SOURCES PRESENT: Green Drakes, 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.
