UPPER ROARING FORK- ASPEN DOWNSTREAM TO BASALT     
                  
FLOW: 272 cfs below Maroon Creek
WATER CLARITY: Big and clear but dropping nicely

OVERALL RATING: 8 out of 10 

FOOD SOURCES PRESENT:  Green Drakes (adults and nymphs) BWO adults and nymphs, midges, golden stoneflies, caddis, PMDs, yellow sally nymphs, sculpins

THE LOW DOWN: After a big runoff, the upper Fork is looking great. The Green Drake hatch is happening in Aspen now.

Green Drakes, BWOs, caddis, yellow sallies, PMDs, golden stones 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. 

HATCHES: Green Drakes 10-12, BWOs 18-22, midges 20-24, caddis 16-18, golden stoneflies 6-10, PMDs 14-18, yellow sallies 16

We are now in perfect floatable shape out there, and daytime hatches consist of yellow sallies, golden stoneflies, PMDs, BWOs, caddis and a few midges, too.

The last hour of light has been excellent with caddis egg-layer action plus PMD spinners.
