Three Creek Lake has been very productive most days and like my report on East Lake it is on a wide variety of things. Last weekend we had a huge run on GREEN beetles. The world of fly fishing is small because so many people came to buy green beetles. 
Black Beetles, Ants, Red Hippie Stompers and even Sunken Ants are good for you up there. 
Callibaetis hatches have been good and should be excellent this week. Nymphs, emergers, cripples, duns and spinners are all on the menu. 
Balanced leeches are another good fly, run it under an indicator with a Red Holographic Jig dropper, or fish that combo on an Emerger Tip. 
Trolling a Sheep Creek Special and a Red Ice Cream Cone dropper on a camo line is a time honored tradition at this lake. It often produces well and its fun and relaxing to kick in your tube and wait for the line to tighten.
