Officials expect another strong season for attendance at the Pella Outdoor Aquatic Center. Aquatics Supervisor Jan Bensink says economic conditions and gas prices may cause people to take shorter trips, which could mean even greater attendance numbers from neighboring communities. Last year over 55,800 people used the facility from June 1 – August 31, according to statistics compiled by the aquatics department. The Aquatic Center opens at 1 p.m. today.
