Check the daily schedule on the east ridge location. They have classes that change periodically.
M-W evenings from 6-7 there is a water aerobics class and no open swimming is available then
6 am - 9 pm on week days. Weekend differs according to the day
Pretty sure it's 6am until 9pm. A couple times a week they have morning classes (aqua aerobics I think) around 9am. Evening classes I'm not sure the time.
I don't have an answer for that. It should be on their website
