An 18-year-old man drowned after he became distressed while swimming in a pond in Plymouth on Friday, State Police said.

The drowning occurred in Charge Pond at Myles Standish State Forest, State Police said in a statement. The forest area is under the supervision of the state Department of Conservation and Recreation.

State Police said the victim was pulled to shore and CPR attempted. He was transported to Jordan Hospital in Plymouth where he was pronounced dead just before 9 p.m., according to State Police.

The victim’s name is being withheld pending notification of next of kin.

Myles Standish contains five camping areas and 16 ponds, according to the DCR website. Charge Pond is a camping and recreational area within the forest, said S. J. Port, a spokeswoman for the conservation department.

Swimming and boating are allowed from dawn to dusk at the department’s facilities, she said.

Port said that there is no lifeguard on duty at the pond, something that is posted on signs and visible to campers.

“We hope that people take caution,” she said.

According to Port, there are buoys around designated swimming areas in the pond, and boating is allowed outside those areas. Campers must bring their own boats.

The bacteria levels in the water are tested by department staff, Port said.

Port was unsure how many campers were at the forest on Friday night, but said that campgrounds were not as full as they typically are during weekends in the summer.

In addition to State Police, officers from the state environmental police and the Plymouth Police Department responded to the scene, State Police said. The Plymouth Fire Department also was on hand.

The incident is currently under investigation by the Plymouth district attorney’s office. A spokeswoman for the district attorney’s office said late Friday night that she did not have information on the death.
