A boy in his late teens hit his head on an object underwater when he dove from a kayak Sunday evening in Lady Bird Lake, said Austin-Travis County EMS.
It happened at about 7:45 p.m. near the South Lamar Boulevard bridge and medics said he suffered a non-life-threatening traumatic injury.
They took him to Dell Seton Medical Center for treatment.
Officials said the public needs to be reminded that swimming is not allowed in Lady Bird Lake for safety reasons. They said that there are numerous hazards and objects hidden under the water, especially near bridges.
