A dive team located the teen within a few minutes, performed CPR and then transported him to Reid Hospital, where he was pronounced dead.
Israel was among a group of about a dozen kids from the Wernle Youth and Family Treatment Center who were swimming in the river, our partners at KICKS 96 reported.
Witnesses said Israel jumped off a bridge and was dragged by an undertow.
According to police, there were some adults near the scene.
Police said there have been no-swimming signs posted in the area before, but they were not sure if the signs still existed.
