    Is food allowed in the Sprayground?
    No. Food must be consumed outside the Sprayground in the park or in the concessions plaza. Non-alcoholic beverages are permitted inside the Sprayground.

    Where are the restrooms and showers?
    Restrooms are located outside of the Sprayground on the east side of the concessions building. Shower rooms are located inside the restrooms and require a key for entry. See the admissions window for access.

    Why is there a capacity limit of 200?
    The Illinois Department of Public Health (IDPH) is the regulatory agency that enforces state laws and requirements for aquatic facilities in Illinois. The capacity limit (maximum bather load of 200) is set based on the size of the sprayground. The perimeter fencing around the Sprayground creates an entry point for staff to monitor capacity to meet this IDPH requirement.

    What happens if the capacity limit is reached?
    If capacity is reached, individuals will only be permitted entry as individuals leave the Sprayground area. We encourage you to enjoy our Mini Golf Course or Concessions if the Sprayground reaches capacity.

    What happens if the Sprayground closes early due to severe weather?
    If our lightning detection system alerts that lightning is imminent, the Sprayground will be temporarily closed. If given the "all clear" alert, the Sprayground will reopen if possible. Weather updates will be posted to the Rainout Line system available for download at dgparks.org.
