There have been a number of double digit bass caught out of the 78 acre lake down the street from my house. It has no shad at all, no Tshad or Gshad. The biggest bass caught has been over 13 pounds and I have personally seen two bass caught that were 10 lbs, 7 oz. and 11 lbs, 4 oz. There are a number of states were Tshad cannot survive but still have double digit state records. But maybe there is a difference between a smaller private pond and a bigger public lake?
