Clark County firefighters were practicing swift water rescues at Wet 'n' Wild Las Vegas on Friday.
As the weather gets warmer, firefighters are responding to more water rescue calls, although they can come at any time.
"As people get cold it's tougher to think. It's tougher to put coordination together so this is a more realistic day just by chance that we might be looking at if we were going to do a real life rescue," said Patrick Foley, with Clark County Fire.
Firefighters have to be ready for every scenario, because if you're in the middle of an emergency they have to be prepared.

"Most people who get swept in the wash they're not neck deep in the wash. Their calf deep, knee deep, thigh deep and their feet get swept out," Foley said.
