MSC,
Does that closure affect private waters?
Yes. I contacted the director of fisheries of the state DNR and he said private ponds are still subject to the state laws. The only exception is if you get a permit to turn your pond into a public pay to fish pond. Then its a circus.
In the 50 some years that the pond has been here, only one time a game warden showed up. You cannot see this pond from the road only on maps.
