Two crew boats loaded with rowers overturned on the Potomac River Wednesday afternoon.
Some of the rowers were able to swim to shore, but many were pulled from the river by rescuers aboard fire boats. Emergency medical staff was on the shore ready to treat for hypothermia or other injuries.
Authorities said the victims were in the water for 15 minutes. Water in the Potomac River at the end of winter is typically 40 degrees Fahrenheit, according to the Maryland Department of Natural Resources.
