They will definitely be around! I checked as well, it might have been September of 21 when I fished river forks for the first time.
I haven't lived here long enough to know, but it seems like you really need to play it by ear for river conditions
My short 2-3 year records show very little for patterns, I've also been here for crazy drought and heavy rains? No such thing has average anymore
With that being said Big K, as long as the water is clear, is a solid bet. Any idea which ramp your heading to?
