I'm sure the section right by the cabins/dam and along their road they stock heavily for their clients. Mud Run has wild fish in it though.
From the advertising, it seems as though it's the owner's intent with the sale to keep it a private, exclusive hunting/fishing club. It's not like there's any access to lose there, since there's no real access (other than a membership) to it now anyway, but I could see this getting into the wrong hands where it's even more "exclusive" than it is now. Though most, including myself, would never pay those kind of yearly dues even if you could afford them, in comparison to some other similar "private fly fishing clubs" out there they're really not that expensive.
Clearly, the ideal outcome is a conservancy or the state somehow acquiring it, and opening up access to the public. Not sure the owners would sell it to those entities though, and at that price I'm sure that's not an option. Most conservancies have land donated to them and don't actually purchase it.
