East Lake is getting a very good afternoon hatch of Callibaetis! You need nymphs, emergers, duns and spinners. The Nymphs should be fished one of 2 ways: Under the indicator with a Jig Style, or stripped with a 3 to 5 foot Midge (Sink) Tip. 
Beetles and Ants and Hoppers are all good too and don’t hesitate to try some small Chubby’s through there, and try a Blue one if you see Damsels and a Red or Royal color any other time. 
Chironomids under an indicator in 10 to 18 feet are good in the morning and after lunch.
