East Lake has been good, with some varied conditions to consider. We are seeing some pretty skinny fish, so winter wasn’t as easy for EL fish as it was for Paulina fish. More on that in a moment. 
Scuds and Callibaetis nymphs are likely your best bets in the shallow zones. 
Add Chironomids once you get out to 7 to 14 feet of depth. Black/Red, Red, Olive all #12-18 plus hanging with my Chromies or the original Chromie with the more silver body and peacock thorax. Red PT and Callibaetis Cate for the indicator fishing is great. Ants, Beetles and Hippie Stompers (red) are good dries during the day, and Purple Haze in the evening. I would hope to see the 1st Callibaetis hatches of the season by this time next week….
