A teenage boy and a man have died after being pulled from the water by rescue crews at the East Mountain Reservoir on the Waterbury-Prospect line Tuesday.
Waterbury police said the two victims, a 17-year-old boy and a 24-year-old man, were floating on an air mattress which capsized, sending them into the water. They were with a group of other young adults at the time.
The victims were pulled from the water by rescue crews and taken to St. Mary's Hospital where they were both pronounced dead. They have not been publicly identified.
The Office of the Chief Medical Examiner will determine cause and manner of death.
Prospect fire officials said swimming is not allowed in the area.
The Waterbury Police Department, Waterbury Fire Department, Prospect Volunteer Fire Department, Prospect Police Department, Region 5 Dive Team and Connecticut State Police all responded.
