Mallory Herring, Pool Manager for the Pella Aquatics Center, tells KNIA/KRLS that while the weather hasn’t been very warm, and the indoor pool is under construction, passes are now available for summer. Herring adds that now is a great time to purchase since it isn’t very busy, and you can buy passes from 7:30am to 4:30pm, inside their temporary trailer parked in front of the indoor pool. The outdoor pool will open on Memorial Day, May 26th at 1pm, and will be open the remainder of the week from 4pm to 7pm, before regular hours begin with the pool opening at 1pm on Friday May 30th.
