An Algona man on Saturday became the third Lake Tapps drowning victim of the season after he and a friend jumped off a bridge on Sumner-Tapps Highway near Fairweather Cove.

The body of Charly Sing, 20, was found Sunday morning by dive teams searching the lake.

According to Dina Sutherland of East Pierce Fore and Rescue, Sing and friend were on their way to a park on the lake when they made a “spontaneous decision” to jump from the bridge into about 47 feet of water in a flume on the western side of the lake.

According to Sutherland, both briefly resurfaced, but while the friend was able to make it to the shore, Sing went back under and never resurfaced.

East Pierce was dispatched to the scene at approximately 7:42 p.m. and conducted what Sutherland characterized as an “aggressive search” for Sing. Divers from Pierce County, Valley Regional Fire Authority and Renton also joined the search, which included two boats and multiple dive teams.

The search was called off Saturday night due to darkness and resumed Sunday morning at 9 a.m. Sing’s body was found approximately an hour later.

According to Sutherland, Sing was healthy and knew how to swim, but was not nearing wearing a life jacket when he jumped from the bridge.

Sutherland estimated the water temperature at the time of the incident in the low-60s and said the shock of jumping into water that cold is believed to have played a role.

“The cold water shock is really what gets them,” she said, calling the effects “brutal.”

Lake Tapps is a man-made lake fed through waters from the White River, the source of which is high on Mount Rainier and often included glacier runoff, making the water cold.

Both other deaths this year in the lake this summer are also believed to be hypothermia-related. Israel A. Godkin of Spring Hill Tennesee died July 10 and Peter Talaga of Kent drowned May 15.

Hypothermia occurs when the body temperature decreases rapidly and blood is redirected from the extremities to the core, making swimming and treading water difficult. Within minutes a swimmer can become disoriented and lose consciousness.

Though the bridge is clearly posted for no jumping or diving, the bridge is a popular spot for diving into the water.

“Please obey the signs,” Sutherland said.
