^ I agree with this. Today we caught a small king (very likely pen-reared) and we even tried fishing for browns in the early morning because the water was stained ideally.
We come up to Lake O annually and last year we caught 140 fish...pretty much anything we threw down was getting hit. Sounds pretty accurate to what you're saying.
I also come to the lake in the spring for browns and this past year was very successful.
But between the weather and your theory and all, I think the fishing is pretty off.
