Three Creek Lake is really fishing well, with callibaetis, black x caddis, chironomids, ants and beetles and bruised balanced leeches being the top flies. 
Evening caddis action is heating up on the x caddis, and tuck a few lady mcconnell’s for any evening chironomid hatches. callibaetis you should see in the afternoon and again some in the evening. 
For beetles we like the jiggy, a red or black hippie stomper and a low floating Crowe beetle. 
It’s hard to go wrong with a sheep creek special and trail a flashback PT on a camo line here. You can kick and troll or anchor and strip with good success on this combo.
