Paulina Lake is fishing good now and is getting a better callibaetis hatch most mornings before the wind comes up. In the morning look for spinners and duns, midge emergers and you have to have a bunch of terrestrials like Hippie Stompers, Beetles (Jiggy Twist and Crowe), Flag Ant, Rp Ant, and Hoppers. 
Red PT, Cate’s, Water Melon Leech, Oange Bead Olive Leech, Orange Bead Brown Balanced Leech and Chironomids. I also like to use a Rainbow Warrior and a Double Down Nymph with a Black Body and Red Rib are good along the ledges with a strike indicator if you want to get down 6 to 9 feet, or under a Purple Chubby off the bend of the hook if you want to fish it more shallow.
