Our stay at the campground was excellent. We went over 4th of July weekend and the mayflies were hatching luckily we weren't close to the water blessing in disguise. One note the boat launch at the campground really is just for kayaks. Trying to launch a normal boat and getting out to the river channel extremely difficult. I gave up. There are lots of submerge trees and it is nearly two miles to the main channel. Best bet if you bring a boat is to drive down to the lock and dam and put in. Best part about the 4th of July no fireworks at the campground so it was relatively quiet.

Beautiful Campground. Be prepared to fight the biting flies and mosquitoes spray does not work.

Sites were paved and level, some provide excellent views of the Mississippi and a slough. Too many speed humps and, of course electric only at site with water and dump available
