The girl was rescued from the water at Round Valley Reservoir in Lebanon with help from lifeguards and her mother around 4 p.m., NJSP Trooper Lawrence Peele told Daily Voice.
Carteret Station Marine Bureau troopers initiated a search with South Branch Emergency Services after witnesses stated that a Hispanic man had entered the water to help the girl but never resurfaced, authorities said.
New Jersey State Park Police and Marine and Aviation Units arrived several hours later to continue with the search as the South Branch agency was finished clearing from the call, Deputy Chief Bucky Buchanan said.
The search came to an end when police found a man matching the description of the swimmer, who had been in the water during the rescue, Peele said.
State Police units cleared the scene by 8 p.m.
“The State Park Police will continue to monitor the park to ensure that all visitors are accounted for,” Peele said.
Local fire and rescue teams also assisted with the search, authorities said.
