Given our experience was on a hot and humid day, I would rate this as 3. However I’m trying to be impartial so I’m putting our temperature discomfort aside and giving it 4. The campsites are large and reasonably priced for an overnight stay.
Campsites are large- some big enough for multiple campers. Most sites have water and electric. Plenty of tall trees around for shade. The sites don't have vegetation between them but they are big enough to give you some room. Restrooms are spread around with one being a shower house.
The lake has boat access. Some kayaks were available to rent. Short hiking trails can be found(with such a large place we were hoping for longer hikes. Playground equipment was getting consistent use today.
Most sites have nobody in them - perhaps during the week is a slow time. There are some sites for long term camping that are clearly designated.
The drive through the touristy area had me guessing as to what this would be like. If simple camping is not your thing, there are a couple of resort type places right down the road.
