A 19-year-old man drowned over the weekend in the chilly waters of Blackridge Reservoir near Herriman.

Unified Police Detective Jared Richardson said that Joey Pantoja, 19, of Copperton, went under the water while swimming about 6 p.m. Sunday, apparently while attempting to cross the reservoir with a male companion, also 19.

UPD said the friend and others at the reservoir attempted to rescue Pantoja but could not find him. Rescue divers retrieved Pantoja from about 13 to 16 feet of water, but he had already been under the surface for about 25 minutes by then.

Paramedics administered CPR for more than a half hour before pronouncing him dead at the scene.

UPD warned that swimming at the reservoir, where no lifeguards are on duty, is risky — especially when spring runoff is still keeping the water cold.

Richardson said the water temperature at the reservoir Sunday was about 60 degrees.
