as far as i know there are no "posted" size restrictions on bass...as far as a limit goes i know it is a 4 to 4 to 6 ratio among bass, trout and catfish but not sure what goes where...i think trout is 6 though....it is fished pretty heavily but mostly just for trout along the dam where deep water is...however the deep water extends far out from casting range from the dam....as far as productivity im not exactly sure of what your talking about...and about vegetation...yes there are the occasional lily pads which pop up every now and then and there is a tremendous amount of grass shallows plotted by big stumps in about 1-4 ft of water.
