We enjoyed our overnight here at Beaver Dam.   Quiet, and very few folks in the park the night that we stayed.

Wifi non-existent.

Zero verizon connection at most spots.

Did not see any staff during our 24 hours there.

Showers were GREAT.  HIGH pressure and clean.

Restrooms were old(er), but clean.

Great level sites.  Good shade on most sites.  Great space between sites, and most had concrete pads.
