Aux Arc is right below a hydro electric dam
Aux Arc is clean and well maintained by the Corps of Engineers. It is in a weird location literally next to the Ozark Powerhouse.
The campground is modern and each site has some nice upgrade with pave spaces and table with small pavilions. Personally I would camp towards the bottom of the campground to try and avoid being forced to stare at the dam.
If there was better scenery this would have a higher ranking. Also, it tends to be geared more towards RVs and Camper Trailers rather than tents, but you can tent camp if you want.
The showers and bathrooms are clean and they have a good crew driving around in thier golf carts keeping everything maintained.
