Thank goodness none of the lakes I fish have overharvest problems - not that our local conservation dept. is of any use when it comes to enforcement of fishing regs. (Though, come to think of it, they only enforce the laws early in the year when it comes to state stocked waters such as trout streams.)

I'm fortunate to live close to a private lake via my club access. Very few anglers keep anything and most that do fish, fish for bass. I could reduce numbers big time but keep nothing. Homeowners just use it for jet skiing and cruising around in circles on boats too large for the lake.

Other public water see few fishing boats on them and not many shore anglers. No sonar is a great disadvantage in lakes deeper than 15' that have steep drops and humps. Are numbers caught in deep water? Not where I fish.
