East Lake is seeing a slow down on callibaetis. I don’t think it is over, but I don’t think with the weather change it is long for the world until next summer. 
Beetles and Ants are still going well. Stripping a leech or minnow or running a balanced leech under an indicator is a good way to find fish for the rest of the season. 
It was about 2015 or 16 I think when our friends Dean & Ilene still lived and worked back in DC and they were out for a visit and I still had my Red Alumaweld boat (Hewes came home in 2017). I’d been to the Phil Rowley Clinic in Sunriver a couple of years before and poo-poo’d the balanced leech idea (I’m dumb and stubborn sometimes). My friend from Sunriver, Phil Fischer whispered an anglers secret to me that brown balanced leeches under the indicator near the EL CG Boat Ramp was doing really well. So…. I tried it with them and while we suffered some on a cold and windy day we had some nice fishing on the brown blanched leeches. This time of year is a great time to hang a leech on any of the lakes and is a top choice on East through the Fall. Right now I would rate East as a 6 out of 10.
