In the United States, drowning is the leading cause of unintended, injury related death of children ages one to four and the second leading cause of accidental death for children under fourteen. Research in this area has shown that the risk of drowning decreases 88% among children ages one to four in those who take formal swimming lessons, like the ones offered at the Boulder City Municipal Pool, located at 861 Avenue B.

This event has been held at in over 56 countries on 6 continents. The WLSL holds five Guinness World Records™ for the largest simultaneous swimming lesson conducted at multiple venues including the current official record which was set in 2014 with 36,564 participants in 22 countries.

Some additional water safety tips include:

• Never leave children alone in and around water. Give young swimmers 100% of your attention during water play. Put your cell phone away, turn off the TV and get rid of distractions. Designate a spotter at parties whose sole job is to monitor what is happening in and around the pool to reduce the likelihood of tragedies.


• Have young or inexperienced swimmers wear USCG approved life jackets around the water. Do not solely rely on life jackets to prevent drowning! Do not rely on water wings or non-USCG approved life jackets.


• Make sure pools and spas have appropriate safety measures like childproof fencing, pool alarms, rescue equipment and that the pool is clean and safe from hazards.


• Learn what to do in an emergency, including CPR.

“This summer will be the last chance to join this fun activity for a while, as the pool is set to close in the fall. We will not be able to hold the event in June 2027, as construction of the new facility will be underway,” said Sierra Coppi, Boulder City Aquatics Coordinator. “Boulder City is home to hundreds of pools, spas, and other water hazards, and our community sits along Lake Mead. There are always risks in and around the water. Data shows that formal swimming lessons help save lives."
