You can purchase potable water from a high flow large hose using coins. However, this water is not suitable for filling RVs. The dump spot and rinse hose are located in front of the public bathrooms. As of June 2017, there is a spigot available at the potable water fill station where you can connect your RV hose. It costs 25 cents for 12.5 gallons of water. Additionally, there is rinse water available, but it is non-potable. The RV dump station is located at I-90 Exit 25, specifically at Coffeen Avenue and Brundage Lane.
