Water Fitness Passes

Lap Swim and Aqua Aerobics and Deep Water Aerobics are a great way to stay in shape. Pick the pass that's right for you; 10 use or 30 use.

 It is recommended that all Water Aerobic classes be signed up for with a monthly pre-register system vs dropping in with a Water Fitness Pass. Purchase fitness passes online or in person at any of our Community Centers.

Water Fitness Updates

• Lap Swim no longer uses a lane reservation system.  Lanes are required to be shared.
• Lane sharing and "circle swim" will be in effect to allow more participants the opportunity to enjoy the program. 

The Walter V. Graham Aquatic Center is ideal for family celebrations, birthday parties, swim meets, practices, or open swim. Enjoy the water slides, diving boards, and the water play area.
