The dump station does not have drinkable water. However, if you ask the campground host, they will allow you to fill fresh water at a campsite. This service is included in the fee for using the dump station. There is rinse water available, but it is not suitable for drinking. The location of the dump station is on Hwy. 2, West Cloverland Drive, about half a mile east of the Michigan Visitor Center. It is on the left side once you cross into Michigan from Wisconsin.
