The Musconetcong in NJ up to the first dam has plenty of gizzard shad, and a few show up below the Columbia Dam on the Paulinskill. Plenty of larger Delaware tribs have gizzard shad, but the Lehigh, Beaverkill and the Paulinskill are the only ones I know with American shad and hickories. Except the hickories go all the way up to the top of the Willowemoc.
