And that's the history as I recall it too.. During that time period (and into the mid 90's) fishermen who are greater than I were reporting large (3+ lb) browns as far down as Prosperine (rarely, but they WERE there, I've hook a few and seen others on gigging trips) I recall one fishing trip in 1997 when I caught one that was 22 inches.
I've heard of folks hooking them in Zone three recently, but I can't drum up one report (local or otherwise) of a "big brown" out of the river itself since the 1997-1998 area, not even the giggers I know. (and yes, they would tell me, these guys are strict C&R of gamefish, we grew up together)
Anybody?
