We stayed October 7&8 2023 and it's a good place to boondock.  No services. A couple of fire pits.  The pit toilet is far from the camping, so don't rely on it.  This area was flooded a few years ago so rocks are everywhere.  A nice 1 1/2 mile trail runs around the island.  People take boats in and out at differing hours so there is some traffic, but is fairly quiet except for the train whistles which I enjoy but some may not.  Tried to get coffee in town at the gas station, but the town's water supply is not working and no one knows when it will be repaired.  Not sure if this is due to the flood a couple of years ago? We plan to return soon.

This would most likely be a last resort for us.  Went to our campsite only to find someone else using it.  Not what you need after driving 400-500 miles.  Had to go back to the office and ultimately took a different site after dirty looks from the poachers.

Then the staff told us there was music that night after we told them we just wanted a peaceful nights sleep so we moved to another site further away from the jam session. Whew a lot of work to be here.  Cannot recall being impresses with the bathrooms/showers.
