MARTINDALE, Texas – Despite triple-digit temperatures, music lovers managed to keep their cool at this year's Float Fest.

For those who stayed on land, they got to enjoy a lineup of twenty musicians at Cool River Ranch. Big names such as Snoop Dog and Lil Wayne entertained thousands. For those who floated the river they were able to stay cool along the San Marcos River.

Hydration was obviously a must for fans who attended the annual festival. Emergency personnel were on site to help those who fell ill.

"I've heard a lot of people going to the medical tent from like heat exhaustion," said Anna Smith, an attendee.

First responders treated at least 250 visitors for heat-related illnesses by Sunday evening.
