Floods: Threats

Floods are one of the most common natural disasters in the United States, and no area is completely free from the threat of floods. In the average year:

  • More than 300,000 people are driven from their homes by floods.
  • 200 flood-related fatalities occur.
  • $2 billion in total flood damages are sustained.
  • Animals that are affected by floods risk death from hypothermia and drowning.

Floods are classified according to whether they are slow or fast rising. Slow-rising floods are typical as floodwaters move down a river or stream and can often be predicted to reach a certain height. Flash floods may occur suddenly following extremely heavy rain, melting snow, or dam or levee failure.
