Gizzard shad do just fine in the reservoirs here. With my ltd experience, I've never heard of any other shad species besides Gizzard & Threadfin.
billy, with a 5 acre pond you could consider using Gizzard Shad - AFTER your Bass get big enough to handle the adult GShad.
Record your temps real good this Winter in the new pond - see how far below 40 deg you get. Maybe adding warmer well water to the warmer depths of the pond in Winter could make overwintering TShad possible.
