Try fishing streamers on the cloudy days. Baetis continue to pop and caddis are sort of around. Worst case scebnarion-try a big dry and a short dropper. Don't nymph. Seriously, just don't do it.
Georgetown lake is iceless and over-run with dingbats of all shapes, colors and sizes. Try red lightening bugs in 14, czechs in 14, olive buggers and even a parachute adams. They will eat a dry if you can put it in front of them. Try to pull yourself away from the spawning fish, and find bright fish out deeper. Piney is a good place to start.
Rock Creek- Clear and low. Salmonflies should make an appearance very soon. For now try a worm, prince or bugger. You can crush 'em with a streamer now too. It is looking like the "perfect storm" is approaching, as flows continue to drop and the weather gets right. Check with Deb at Trout Bums for dry fly info. Remember that she has a great little shop about 8 miles up. Hot coffee and accurate info can be had there. www.rockcreektroutbums.com or you can hit up the Rock Creek Mercantile-406-825-6440. They have up to the minute reports about logjams, shuttles and bugs.
Clark Fork-Upper is low and mossy. Whattup run-off? Lower-Looks a bit like mocha, but I'm betting it's gonna be in soon. Really I think the best early June fishing in years is nearly upon us.
As an aside:
Ben Hahn, fishing with RFO guide Zack Lazzarri nailed this measured 29" brown on Rock Creek on sunday. This fish was released somewhere in the creek and might get caught again. What a freaking MONSTER! My question: How many 9" browns has this old boy eaten? Not enough. Keep those little fellas for the BBQ! Btw, Ben;s a pretty darned fun guy to fish with, if you're in the Livingston, Montana area. Contact us and we'll get you in touch with him. He's a good cat.
