Stayed one night, 10/15/22 on a road trip out to the Midwest. It was dark when we pulled in, hard to see the landscape/campground sites, but we found one right on the edge of the reservoir. There were multiple other RVs already set up, hunters mostly this time of year. Vault toilet, picnic table and fire pit at the campsite and some trees. Not very many trees between campsites, so don’t expect too much privacy. It was very windy the night we stayed. But it was free, close the highway 2, and open all year long. I saw no trash services or water but that could be the time of year. Very close off highway 2, maybe a 3 minute drive past the sleeping Buffalo hotsprings.
