Rescuers searched Thursday for a man who sank out of sight while swimming south of the confluence of the Sacramento and American rivers at Tiscornia Park.
The man, who officials believe is 18 or 19 years old, went under at about 2 p.m., said Assistant Chief Kim Iannucci of the Sacramento Fire Department. He is believed to be wearing white swim trunks. He was not wearing a life jacket.
Emergency responders arrived within two minutes of receiving reports of the swimmer going under, and began searching the area using a team of swimmers and a helicopter, Iannucci said. They deployed a boat from the Yolo County Sheriff's Department equipped with sonar.
The fast-moving river is dangerous for swimmers, Iannucci said. The river's depth changes abruptly, and has frigid pockets of water along with snags that can trap swimmers, she said.
"The river is very deceiving," she said.
