These fish are physicaly responding to lake conditions the same way as an ocean fish responds to ocean conditions, the kokes in that lake have increased to these sizes due to a bloom of a high nutrient fresh water shrimp, if the shrimp hold out, the kokes will remain big, if the shrimp diminish, expect to see the same in the fish. I think the record breaker is still in there, it takes a talented or very luck fisherman to land such a large soft mouthed fish that have pretty good spunk... im sure the record has shook a hook a couple times- Brad
