East Lake is seeing strong Callibaetis and Damsel hatches, and you can expect dry fly action with different stages of callibaetis throughout the day. Damsels are more of a late morning and early afternoon occurrence. Remember the Blue Chubby and Extended Body Damsel combo when you begin seeing fish eat aggressively, or even see some leaping in the air to eat a hovering adult damsel. Ants, Beeltes and Hoppers will mostly round out the dry fly selection, although I’ve encountered plenty of summer mornings before any wind happens with midges. 
Chironomid fishing under an indicator in 15 to 18’ is good, sometimes really good. Also, try that Type 7 dangle technique in deeper areas and even if you don’t have live scope, trust doing it for 30 minutes and see what happens. 
Stripping or static techniques for Callibaetis nymphs is very good. A Hover or Midge Tip is the line of choice for the strip, and both of those lines are great for bank anglers tricking fish eating emerging damsels each afternoon along the shoreline.
