Some lakes here they get round and others they grow long and lean. I think it has something to do with the forage base. Lakes with a lot of snails, clams and crayfish Redear seem to be fatter than lakes that don't have the big forage base that they prefer. Watched the conservation department stock 2500 3-4" redear into a 5 acre lake a couple of days ago. Apparently the lake is loaded with yellow snails and are clogging the sewer drains and aren't allowing any run off. Lake overflowed and there was 3" of water on the sidewalk around the entire lake.
