Rescue workers were continuing to search on Friday for a 19-year-old man who is believed to have drowned while swimming in Triadelphia Reservoir.
Montgomery County Fire and Rescue Service spokesman Pete Piringer said the man was swimming on Wednesday afternoon near the Greenbridge Recreation Area with a group of about a dozen people, all in their late teens and early 20s.
Swimming is prohibited in Triadelphia Reservoir.
“They attempted to swim across the cove, and he went down and didn’t resurface,” Piringer said. “They were able to call 911 pretty quickly, and units from Howard and Montgomery counties esponded at about 6 p.m.”
He said officials deployed boats, incuding the Sandy Spring Volunteer Fire Department’s water rescue operations, and searched the shoreline. They are using sonar and thermal imaging, he said.
They search continued Wednesday evening until a storm caused the operation to be suspended.
The search continued throughout the day Thursday. Rescue teams went back out Friday, assisted by the Charles County Dive Team.
Piringer said it could take several days for a body to surface, depending on air temperature, water temperature, depth of the water, and the decomposition of the body.
“We are hoping to find the body before that actually happens,” he said.
