East Lake is good fishing, I would also expect this week to see the 1st callibaetis hatches of the season, but plan to fish a lot of chironomids and pheasant tails.
Work the shoals and shorelines in water 2 or 3 feet deep up to about 10-12 feet at this time. I would not expect the fish to be needing to find anything in terms of food, shelter or better water temps in deeper zones at this time. This week make sure to tuck some #10-12 flying ants in your box. That is a likely hatch with 80 in the forecast Wednesday.
