How deep does fast-moving floodwater need to be to knock over an adult?

Just 6 inches.

  1. 6 inches ✔
  2. 3 feet
  3. 5 feet

Why: Fast water is much stronger than it looks. Six inches can knock over an adult, so never walk or wade into flood water.

Huh, didn't know that: The National Weather Service says 12 inches of rushing water can carry away most cars.

What did the river say to the hiker? Water you doing here?
