This campground is located just off the Sturgeon River in the Ottawa National Forest and is first come first serve with no reservations. From speaking with a local who frequents the campground, it is usually quiet with few sites actually in use at a time; it seems this year (2020) there have been more people out camping, though, so getting there earlier is better to ensure finding a site.
It is rustic -- there is no water pump, but there are pit toilets in the center of the site. If you don't bring enough water the river next to most sites can provide drinking water with the proper filtration. The national park website says there are 9 sites, but only 7 are actually available. My best guess is the MIA sites existed in the central part at one time.
Two sites can fit a camper, but they also happen to be the sites with the best view of the river. The remaining sites are tent-only due to a set of rocks blocking off the sites so vehicles do not drive in. From what I could tell with observations, 4 or 5 sites are either right on the river or have a short trail to get to the river.
The locations are sparse enough that the only thing really heard from other campers is the occasional shutting of a car door. The soft sound of the river drowns most noises out. Each site has a fire ring, most have a grate on the ring, a lantern hook, and a picnic table.
