One important thing to mention is that today East Lake got pretty green. I can’t be sure if this is a turnover of some kind, I wouldn’t think so as the water temps start in the morning about 54 and get to 60-61F in the afternoon. So it’s not a cold sink mixing with the bottom and bringing junk up. What I suspect is a heavy pollen coating on the surface is contributing to a surface algae. As of this evening, I would not choose to go back to East for a few days and let that clear up. In some places there was zero issue, but the water was much greener all over the lake than it was 2 days ago. 
Speaking of 2 days ago I had a couple of guys from Project Healing Waters, Val who runs the program in Central Oregon and Colin who is a volunteer. They put the smack down on the fish! We used a drop back bung with a black chironomid/red but/silver rib in the morning with a lot of good fish. Also the Croston’s callibaetis and the CB cate nymph were just producing a lot of bobber downs. 
When the callibaetis hatch came off the tilt wing dun was all we needed. I tied one on for Colin as the hatch began and he immediately was catching fish on it. 
After lunch the hatch subsided quickly and we moved to loch style drifting with the drogue and fished jiggy beetles off the banks, and ended the day in the deeper waters with a type 7 full sink deep dangling duct tape’s and Val caught one of the biggest browns of the season so far doing that. 
Today the wind was strong (and cold) from the west, and callibaetis were virtually non existent, but we did okay on the nymphs I mention above. Beetle action was consistent and we got one decent brown on a deep dangle with a duct tape fly in about 30 feet deep out from the resort. 
Many thanks to the East Lake resort for their docks and their fair price to use the launch and park there. For $5, for me to be able to have a safe place to launch an 18 foot boat is a gift. East Lake has been my go to spot for fishing since about 1973, and the resort makes it just as special today as it’s ever been.
