9 year old 6 acre trophy bass lake flooded from the Harpeth River during the 2010 middle TN flood. Crappie and gizzard shad came in, and lots of trophy bass literally went down the drain. This spring, a beautiful 12.3 pounder was caught, photographed and weighed, and successfully released. Several bass in the 8+ range were caught this year, but now catching 10 crappie to 1 bass. will start draining this week, will take 40 days to drain with 3 hp 3" suction electric pump, lake was designed so that all water gathers in very small valley near the spillway, exposed 40 mil liner on the entire floor of lake. Since water temps will be favorable, and would be simple to build small dam just above collection area, should I save the shad, big bluegill, and huge bass? I was advised by a few experts to start afresh for balance reasons....Jeff J
