East Lake is impressive with the Callibaetis action. I had a couple of very fine mornings this past week with a Callibaetis nymph under an indicator. Lots of fish to the net with this in about 9 to 14 feet of water over weed beds. Having the live scope is interesting because I can see the fish in real time doing what we would expect during pre callibaetis emergence and that is chase ascending nymphs up from the bottom, but also take the descending nymphs as the nymphs take 2 or 3 attempts to swim to the surface for emergence. So the fish are looking for them to feed on the nymphs in 2 directions. How cool is that? The hatch is hard to match. 3 flies that have been better than most are the White Extended Body #16, a Harrop’s Captive Dun and a Grey Comparadun #16. The Nymph that is the best is a Callibaetis Cate, and a Red PT Jig is right up there and Crostons Callibaetis Jig is also money. 
Spinners are usually prevalent in the AM. 
Beetles, Ants and Grasshoppers are good along the banks. 
Chironomid fishing is good from 12 to 18 feet with an indicator, and from 19 to 35 feet on a type 7 with a dangle approach. Red seems to be the best color, but I have been having some success with Lime and Chrome too. You can never go wrong with a Black Ice Cream Cone when fishing Chironomid Pupa.
