I agree with Andy.  There is generally a large enough area to accommodate the overnight  campers at the Cedar Creek Park H/B campground.  In the unlikely event that it were full there is a pay-to-stay campground with showers in West Newton just 3 to 4 miles away.
Note however there is a Family Funfest planned at the park for Sunday August 6.  If your plans were to slip into this date, you may find things a little more congested in the park that weekend.
