East Lake is fishing well and on most days you can expect a good late morning callibaetis hatch that may extend to mid afternoon in different stages of the hatch. Also the evening hatch is really good by the white slide. 
Ants, Beetles, Hoppers, Blue Chubby and Adult Damsels are good on the top too. 
If you are there early in the morning it is likely that the fish are going to be taking small midges at the surface. 6x tippet and #18 or 20 Griffiths Gnat ought to fool a few…..
Deep Water nymphing in 15 to 30 feet of water with Chironomids, including Red Blood Worms is good. In water 15 to 18 feet I like a slip strike indicator on a chassis leader and 2 chironomids tied on my tippet spread about 24″ apart. 
Balanced Leeches, Callibaetis, Red PT, Red Holographic Jig, Damsel Nymphs (including shoreline action) and Scuds will be good nymphs to cycle through each day.
