Little Lava Lake is very good, with a lot of fish coming before and during the callibaetis hatch. Shallow Weed Beds are the name of the game for these mayflies and Little Lava has that habitat in spades. I also fish a lot of Flag Ants and Jiggy Beetles here, and not nessecarily right on the shore like so many other lakes. One fun thing to play with here is get out to the 12 to 15 foot zone and use your midge tip with a Red Ice Cream Cone on the point and a Poxyback Callibaetis on the dropper, cast it 40 or 50 feet, let it sink 20 to 30 seconds and slow hand twist it back to the boat.
