**Swim Meet Partial Closure: Due to Sea Lion Swim Team home meets, the lap lanes and a portion of the zero-depth area of the main pool will be closed on the following days and times listed above. Every attempt will be made to allow as many portions of the park to remain open; however, Sea Lion Aquatic Park Management reserves the right to close designated areas if circumstances warrant. Thank you for your understanding and cooperation.
*Passholder Appreciation Night: The pool will be closed to the general public and open late just for Sea Lion Aquatic Park season passholders!
^Independence Day: The pool will close early on July 3 due to the Lisle Park District Summer Entertainment Series in Community Park. Ohio Street will be closed at Yackley Avenue beginning at 4:00pm. No through traffic is permitted and no public parking is available short of Handicap parking on the North side of the High School. Short Street will be closed at Route 53 once the Riverview parking lot is full. Parking here is limited so the closure could take place shortly after 4:00pm.
