SHERMAN, Texas (KXII) - A day of fun at the pool or lake can turn tragic in seconds.

That's why it's critical to know the signs of drowning.

When taking a swim, it's important to keep a watch out on the water."It's not the lifeguard's job to individually watch each kid, its their job to enforce the rules, that they're safe, and to save them if it comes to that point," said Ella Woody, lead lifeguard at The Splash Family Aquatic Center in Sherman.
