There is potable and non-potable rinse water available at the RV dump station. To get there, you need to take I-70 Exit 37 and drive east to 400 West. The first road on the left after the KFC/Taco Bell is where you turn. Look for a big billboard on the left immediately after the road. From there, go north on 400 West until you reach 600 South. Turn left and follow that road to the campground.
