Exonerated Drakes In Jurrasic Pk 18Aug17

I finally caught the tail of the green drake hatch on the Blue below Green Mtn Rez. Being gone so much of July left me wanting for the tug on the big mayflies. Exonerated means that I caught multiple fish on my custom ties of green drake nymphs from 2016 (stymied that season, late). Today I landed many smallish browns and only one nice 17" cutbow - several on the drake nymph. I tried hard but got nothing to surface to the drakes - though my daytime timing was not perfect; I have guests and need match the activities. Perfect weather - plenty of drake and PMD signs in the canyon still, and caddis too, but the flows are still strong ~550cfs so no crossing to hit all feeding lies - floaters still ruling the roost.
