Man dies after being rescued at Walden Pond

A 32-year-old man who was rescued and hospitalized after going underwater at Walden Pond has died, the Middlesex District Attorney’s office said Sunday.

State police responded Saturday around 7 p.m. to a report of a man submerged in the pond. According to officials, the individual was taken to Emerson Hospital in Concord and listed in critical condition Saturday night, but died at the hospital Sunday morning.

No additional information is being released, according to the district attorney’s office, as the death is not considered suspicious.

Walden Pond, which is a state reservation, is open from 7 a.m. to 8 p.m., according to its phone information line. Lifeguards are on duty at the pond’s swimming area from Memorial Day to Labor Day, but, according to The Boston Globe, only from 10 a.m. to 6 p.m. on weekends. In 2013, a lifeguard at Walden Pond saved a 7-year-old boy who had become unresponsive in the water.

For the first time in 2014, state officials made open-water swimming, already a popular activity at Walden Pond, legal at the state park.
