Walnut Creek Campground is privately owned, Walnut Creek Boatramp is Army Corp of Engineers.
The Campground is very basic with campers parked in U configurations which works well if your with a group. I noticed though that the grass was a little long throughout the campground and the sites are all grass. Not sure if there was a lot of rain how firm the ground would stay and how much standing water tgere would be.
The tent area was across from the campers and at the very end in a shaded area. You have a lot of room to spread out and plenty of grass to pad the ground your sleeping on.
Porta pots are the available facilities, I did not check for freshness.
Down the hill is the Boatramp and Marina, which looks older but maintained. A nice area for a relaxing pleasant summer day.
