Roaring Fork River Report 8-1-19

UPPER ROARING FORK- ASPEN DOWNSTREAM TO BASALT
FLOW: 856 cfs below Maroon Creek
WATER CLARITY: Big and clear but dropping quickly
OVERALL RATING: 6 out of 10 due to the higher than "normal" flows. Some spots are tough, others are easier.
FOOD SOURCES PRESENT: BWO adults and nymphs, midges, golden stoneflies, caddis, PMDs, green drake adults and nymphs, yellow sally nymphs, sculpins
THE LOW DOWN: In general, this will be a big water year here in the Roaring Fork Valley. The Green Drake hatch is happening pretty much all over the Fork this year at once. The upper river is still higher than normal, but the flipside is that there's no mystery where the fish are hanging out....right in the soft stuff and near the banks.
BWOs, caddis, PMDs, golden stones, green drakes and midges are the main food source, but leading with a stonefly or prince nymph could get fish looking. When fishing the upper Fork, especially at these flows, focus on the soft water near the banks. We're starting to fish some larger bugs on heavier tippet, but you may need to revert to small flies and tippet if the river is running clear.
Make sure to wear some studded boots or bring a walking staff, fishing from the middle of the river opens opportunities for multiple drifts and picking off every pocket a trout could hold.

MIDDLE ROARING FORK- BASALT DOWNSTREAM TO CARBONDALE
FLOW: 1240 cfs in Basalt, coming down nicely
WATER CONDITIONS: Dropping significantly, clear
OVERALL RATING: 7.5 out of 10
FOOD SOURCES PRESENT: Caddis, green drake adults and nymphs 10-14, Midges, BWO adults and nymphs, golden stoneflies, craneflies, PMD adults and nymphs, worms, sculpins
THE LOW DOWN: The green drake hatch this year is already noticeably different, as we usually see them first down low on the Colorado and Roaring Fork and they "roll up" the river a few miles every day. This time around, we are seeing them hatching from Aspen all the way down to Glenwood, right now, all at once! To be frank, the green drake hatch at twilight has been a bit tough this year. We've seen plenty of bugs at twilight, but the fish aren't keyed in on them like usual due to higher flows.
See the lower report on how to effectively fish this twilight hatch.
HATCHES: Green Drakes 10-12, Caddis 14-18, BWOs 18-22, Midges 20-24, PMDs 14-18

LOWER ROARING FORK- CARBONDALE TO GLENWOOD
FLOW: 1700 cfs in Glenwood Springs, down significantly
WATER CONDITIONS: Clear and dropping. Still a bit high but fishing well.
OVERALL RATING: 7.5 out of 10
FOOD SOURCES PRESENT: Green Drakes, yellow sallies, caddis, midge adults, BWO adults, emergers and nymphs, PMD adults, emergers and nymphs, rusty spinners, worms, craneflies, sculpins
THE LOW DOWN: As mentioned above, the Green Drake hatch is happening right now, from Glenwood all the way up to Aspen, all at once. Considering the higher than normal flows, find the softest water you can around twilight and get your headlamp and dry shake ready to go! These big mayflies come off right at dusk, so be patient and wait for the magic out there just as the light is fading. The hatch isn't 10 out of 10 yet, but is steadily improving every night.
We are finally back to floatable shape out there now, and daytime hatches consist of yellow sallies, a few green drakes, golden stoneflies, PMDs, BWOs, caddis and a few midges. Be mindful of the swift water and choose your battles when it comes to where you choose to fish. This will be a high water year in general, so this is everyone's opportunity to learn some "high water tech."
HATCHES: Green Drakes 10-12, Caddis 14-18, BWOs 18-20, PMDs 14-18, Yellow Sallies 16, Midges 18-26, golden stoneflies 6-10
