Paulina Lake is on the list of go to places even though I am disappointed with the average size of the stocked Rainbows this season. Beeltes, Hoppers, Ants, Hippie Stompers and a few straggler Callibaetis duns around. It is amazing how much different the Callibaetis hatches are between here and East. It has to do with the shoals at East compared to the vast deepness at Paulina. 
Leeches, Minnows and Chironomids and that Double Bead CDC Black Assassin are good bets now.
