Rob,
You hit the nail on the head with your last paragraph. Lakes need to be managed on an individual basis, depending on the various circumstances of each lake. I think the only exception to that would be the statewide crappie regs. Crappie are on such a downward spiral all across the state, I'd like to see the limits on them changed to a max of 10 with a minimum size of 10 inches.
Anyway, I'm really sorry to hear you've got spots in there. I consider them pests. Almost as bad as pike.
