Wristbands are earned by a one-time deep-water swim test. Swimmers are required to successfully swim over and back in the deep end (diving well) using a front stroke or breast stroke. The test is administered by a lifeguard during the designated deep-water test times. The lifeguards’ decision is final.  Wristbands can be obtained at the admission office daily.
