I havent been there for a few years either…my old roommate from college lives right there and ussually calls when it is getting good. I have fished in the boat and from shore and prefer to fish from shore(with the crowds) right below the refuge area. Depends on the water depth but almost always fish a firetiger shallow shad rap. If there is alot of water coming through the gates I will be there the first week of April.
My biggest walleyes to date are a 31 and a 32 1/2 and both came from the Fox River.
