The lake water is cooling off as summer is quickly winding down. Now is the perfect time to visit Westlake Aquatic Center where the water is consistently 86 degrees. We have a full schedule at Westlake. We are open 6 days a week. Monday through Friday we are open at 6 AM for Lap Swim. Daily we have two fantastic Water Aerobic workout classes. One begins at 8 and the other at 9 AM. Following the WA classes there is an Arthritis/Wellness Class which begins at 10.
