We tent camped in the non electric sites in the Lower Campground. They were shady thank goodness, but not very flat or large. Your tent will be on rocks, not grass.
When we were visiting, the shower house was closed due to Covid, so no review of that. The vault toilet was stocked with TP and fairly clean. The portapotty was near full and smelled awful. Didn’t look like it had been emptied all summer! Gross.
The lake was really high when we visited, which led to a useless campground fishing pier and a boat dock that you had to swim to to use. There was no beach, but there may have been if the water level was normal. Watch out for biting sunnies in the swim area and enormous snapping turtles stealing the fish off your hook at the fishing pier near the swim area.
We did go into Starbuck which is 5 miles away. Very impressive beach, groceries and a DQ all an easy drive away.
