During floods, average stream velocities in Flower Mound can range from one to sixteen miles per hour. When you consider that just one cubic foot of water weighs 62 pounds and the typical flow rate during a flood can be several thousand cubic feet of water each second, you can imagine the immense force that flood waters will exert on anything in their path.

- Avoid walking through flood waters. A mere 6 inches of fast moving water can knock over an adult.
- Do not drive through a flooded road. It takes just 12 inches of flowing water to carry off a small car; 18 to 24 inches for larger vehicles. More than half of the deaths from flooding occur in vehicles.
- Move to higher ground. Flood waters can rise very fast. If there is a chance of flash flooding, move to higher ground immediately. Flash floods are the #1 cause of weather-related deaths.
