All sites are reservable but they do allow single nights on open sites. There is an area for overflow (dry camping) but don’t know if they allow you to use it. NOTE: No water for tanks or hook up.

Yes they have 6 overflow sites. No electric no generators and now no water. Don’t know if they charge $30

It was all reservation..they do get busy this time of year

No first come first serve, but many sites are available without reservations due to them not providing water

I’m not aware that there are. The website doesn’t mention it so I would call the campground and ask.
