East Lake is just excellent with Callibaetis now. Fish the hatch from 9 am to 2 or 3. Might last for several hours on any given day, and it could be shorter on some days, but fish are looking for emergers and duns and spinners of our favorite lake mayfly. When I guided there 2 days ago, after the hatch we worked the fish with black beetles #14 and got into some great fish on that too, and a couple on Ants.
