The Ernst M. and Helen S. Ruder Outdoor Waterpark at the East Butler County Family YMCA includes a splash area and two waterslides for kids and adults of all ages to enjoy! 
The outdoor pool closes when thunder or lightning is in the area or if the air temperature is less than 70°F. Updates on closures will be posted on our Facebook page. 
Swim Policy:
For the safety of our children, a swim policy is strictly enforced. Youth under 16 years old MUST wear a swim band while in the facility. Anyone wishing to take a swim test should talk to a lifeguard. Those who decline to take the test or do not pass the swim test are considered non-swimmers.
Guest Passes & Nationwide Membership - Due to capacity restrictions, our facilities are open to Great Miami Valley YMCA members only. 
  • No Reservations Required Labor Day Weekend
  • Labor Day Weekend Hours : Saturday 11am-7pm, Sunday 12pm-6pm, & Monday 11am-6pm.
  • Weather closures : If we need to close the pool due to weather complications, you will lose that reservation and need to make another reservation for your next visit.
