Two recreational boats collided on Saturday in the Colorado River along the California-Arizona border. Thirteen people were injured and two were missing, the authorities said. At around 8:00 pm, San Bernardino County Fire staff responded to Moabi Regional Park, a recreation area about 290 miles east of Los Angeles, where crowds gathered to celebrate Labor Day Weekend, Victor Valley News reported.
A boat occupant sustained fatal injuries and was taken to the University Medical Center in Las Vegas, said Eric Sherwin, a spokesman for the San Bernardino County Fire District.
Six more were taken to smaller hospitals for less severe injuries, while a further six had only minor injuries.
Some passengers were reportedly thrown into the water by the force of the collision or jumped and swept down the river for several miles
"We had victims of this collision who were located 3 to 5 miles downstream from the original point of impact", said Sherwin.
Divers were turned off, looking for the remaining two people until the effort can be resumed Sunday morning. The depth of the river ranges from shallow to 30 feet deep, Sherwin said.
Sonar of the submerged boat did not appear to show any of the missing persons on board, he said. The other boat was severely damaged by the impact, but remained afloat.
Other pleasure boats came together on the scene and downriver to help with the rescue of victims, Sherwin said.
