AUSTIN — A missing boater was found alive Friday morning after a violent boat crash overnight on Lake Travis, Austin-Travis County EMS confirmed to KVUE.

Medics say they believe the boat hit a sandbar around 11 p.m.

Crews searched for several hours, and they found the missing person at a home nearby. He was sent to the hospital with non-life threatening injuries.

ATCEMS said six people were in the boat at the time. Two of them had to be taken to the hospital in a helicopter with extensive injuries.

Another was sent in an ambulance while two people refused to be treated.

With the weather warming up, officials say people need to remember to be safe while they're out on the water.

"It is not a good decision to be on Lake Travis after dark. There's a lot of hidden structure, the lake levels fluctuate greatly, there [are] submerged trees," EMS said.

Each person on the boat is expected to be OK. Currently, Lake Travis is about 13 feet below full. And when lake levels get lower - that increases the danger of boats hitting the underwater debris and sandbars, officials said.
