Too many Grass Carp can be a problem if you want some vegetation. Too many crawfish might do the same thing. Lake Conroe located near Houston Tx was stocked with too many GC and it made the lake much tougher to fish but it still produced some larger lmb. It is getting better everyday because the GC are dying off of old age. I read where Bob Lusk had a situation where he needed to reduce the roaming in a lake, so he added cover to the lake. And that seemed to help the fish and the fishing. It might take a lot of work on a lake or your size but I would start in an area and add as much cover as I could. Like fish attractors and such to hold the fish in an area. After you get 20 to 30% of cover in that area then move to another area and do the same. Do a point and then another point. I can tell you from personal experience, you can make cover from a lot of different materials. Pvc scraps, tires, pallets and tree limbs etc.


Do not judge me by the politicians in my City, State or Federal Government.
