I went tent camping here with the family; Things were left a little to be desired due to lack of shade + noisy nearby road, but overall things went fine for us. This seems to be a great spot for RVs and groups with ATVs who want an inexpensive long stay.
Pros: Free. Flat ground. Easily car & RV accessible. Nearby ATV trail (We didn't visit but others said it was great). A couple of large open sites for big RV groups. Three(?) decently shaded places for tent camping. Town with small convenience stores about 2 miles away. Fishing at the reservoir about 3 miles away (we caught trout, saw turtles, saw boat/canoe rental shop). Elk River Falls hiking trail about 7 miles away (2-4 mile hike depending on what you see)
Cons: Not a ton of shade overall. Nearby road is loud, traffic even during sleeping hours. No picnic tables. 10 sites but mixed bag of what was developed – couldn’t tell what was a site in some cases (downed branches, overgrown grass, etc.)
Other Notes: Fire pit is a circle of stones/no grill. Saw a couple of small standing grills for coals at various locations. Not much to explore immediately off camp, need to travel a little but easy to get anywhere.
