WACO -- A sunny afternoon at Lake Waco quickly turned tragic on Sunday.
"This is not how we want to start the summer," said Park Ranger Liz Anderson.
One minute four-year-old Cheyenne Kieran was playing in the water with other kids....
The next he was found floating in his life jacket near the bank.
"This is just unfortunate. It's unfortunate for the family. It's unfortunate for the baby," said Anderson.
That same day at Nolan Lake in Bell County, 31-year-old Albert Gonzalez drowned while trying to save his daughter after a horse they were riding, fell into deep water.
Now lake officials are reminding everyone to be cautious.
"Knowing how to swim is the most important thing, as a person or as a parent," said Anderson.
Park Rangers say swimming beyond the designated swimming areas is a high risk because those areas are man made and any part of the lake beyond the yellow rope is sure to have underwater hazards.
"Every time the wind blows it moves those hazards around so just because it was a safe place to swim yesterday there may be an underwater hazard that you can't see now," said Anderson.
Also wear a life jacket and always watch your kids carefully.
"It only takes a moment for a child to drown," said Anderson.
