Paulina Lake is also fishing well, and like East Lake the beetle and ant game is a winner. Callibaetis are later to hatch on Paulina and one brood usually shows up well enough in July and August, so I would not expect too many dry fly callibaetis yet, but the nymphs are already killing it. Other nymphs to make sure you have on board will be scuds, hanging with my chromies and ice cream cones, assassins, double downs, watermelon leech, vampire leech, brown spectrum leech and red PT’s. 
You can strip nymphs and leeches and chubs on sinking lines from type 3 to 5, or hovers and intermediates in the shallows and try to use a midge tip/ermerger tip line off some of the drop off’s where weed beds are prevalent, its a fun way to present some of the same bugs as under an indicator and is more active. A balanced leech retrieved on a emerger tip is a killer combo. 
I had a really good conversation this afternoon at closing time in the shop with Gavin (Camp Sherman Dad) about a bright blob on a system like this with another nymph or leech on a tag. He believes the brightly colored blob attracts the fish to the area, maybe they look at it and then there’s a leech or chironomid or mayfly that is more natural to eat close by. Fish on! Our friend Phil Rowley thought the same thing was important when doing the deep dangle and that a blob drew the fish closer to the chironomid hanging down there on a type 7 full sink line 30 feet deep or so.
