As far as fishing goes, I got out on the Winooski yesterday afternoon for a short time right after the Thunderstorm rolled through and the water rose. I nymphed up a few Rainbow's which were holding in a long narrow depression in the middle of a riffle that is around 1/4 of a mile long. This means that fish have been willing to venture into summer feeding lies now that the water temps have warmed into the 60's and bugs have been popping. I did not have any action on the swing, but from now on I would recommend swinging every drift and slowly stripping your nymphs back to you.
I saw a few caddis, a few Hendircksons, and a fair amount of Blue Quills. I flipped some rocks and sticks and there were a LOT of Golden Stonefly Nymphs crawling around. I saw a variety of sizes from about a 10 to a 6, in fact a #10 double bead golden stone nymph was the hot fly yesterday for me.
My go to flies for the week will be Golden Stones, PT nymphs, Lafontaine's Sparkle Pupa in chartreuse, a green and purple caddis pupa imitation, Zug Bugs, Princes, and Hares Ears. We may see a few rising fish but I doubt there will be many.
