A 6-year-old boy died in the "wave pool" attraction at the Great America Amusement Park in Santa Clara, California.
Two life guards were in the pool and four more were positioned around the pool, which is the size of half a Football field.
The attraction containing 355,000 gallons of water generates large waves and at its shallowest is zero feet and it's deepest, six feet. It was unclear whether the boy's mother was supervising him directly.
