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.
