Interesting report! I fished yesterday too and i was curious what others did so Thanls.
From 6:30 to 8:30 the bite was on fire, you couldnt keep lines in the water. At 8:30ish it just stopped, like instantly. I covered a lot of depths from 9 or so to 11, no bites so started to pull lines etc and had a "chubby" hit but didnt get it.
I havent had a "dead period" like that this year. Very weird day, you just missed the early craziness
Good luck
