As you have asked about the rules of the Swim School of Stanford Campus Recreation Association (SCRA), I am giving you some information about it, check below for the details
Pool Rules & Usage

Lifeguards are in charge when on duty.
Swimming is at your own risk.
No sitting on or swimming on top of the lane lines.
No crossing lanes in which people are lap swimming.
No running on the deck, please walk.
No diving in the shallow end of the pool.
No pushing or throwing people into the pool.
No glass or food within 10 feet of the pool.

Diving Area Rules

No running is allowed on the diving board.
Only one person on the diving board at a time.
Only one bounce before jumping off the diving board.
Make sure the diving pool area is clear before you dive.
Once you have completed your dive, immediately swim to the side walls to clear the area for the next diver.
Swimming in the diving pool is not allowed when someone is on the board.

Baby Pool Rules
The "kiddie pool" is for babies and small children under the direct adult supervision of parents or adult guardian.

Children who are water safe and older than six years should NOT play in the baby pool.
Children in the baby pool area must have adult supervision at all times, even when there are life guards present.
Absolutely no diving into the baby pool.

Swimming Attire
Everyone must wear a swim suit

Swim diapers are also REQUIRED for children who are not yet toilet trained. The diapers should be age/size appropriate, and should feel very snug on your child.
Wearing a swimming cap or hair tie is optional – although they will keep hair out of your face during those important moments when seeing and breathing are essential.
