There were no lifeguards on duty, but life jackets were available at the park. Mongillo noted that with some 100 people in the water, it can be difficult to monitor everyone. This is especially true when more people come to the lake to cool down on a hot day.

"I can’t stress enough how important a life jacket is to wear – especially in this weather," Peter Mongillo of Snohomish Regional Fire and Rescue told FOX 13. "It’s beautiful but the water is bone-chilling cold. It’ll suck the energy out of you."
