I've been to Hamilton twice in the last few years and both times fishing was great. Caught plenty of hybrids and a few nice walleye up on the north west side of the lake toward the damn. There are good stripers in hamilton as well but we didn't have as much luck with them, I would recommend getting a guide to take you out on Ouachita while you are there which is the lake above the Hamilton dam.
