After a late-May snowstorm and continued showers, South Dakota has received an immense amount of moisture this spring. This onslaught of precipitation has created a risk of flooding throughout the state. According to the National Weather Service’s (NWS) 2019 Spring Flood Outlook, the threat of flooding across South Dakota ranges from “above” to “much above” typical rates.
“With winter behind us, South Dakotans are eager to get back outdoors; however, I encourage everyone to stay informed on updated flooding information and plan your activities with safety in mind,” said Larry Jaudon, director of the Environment, Safety and Health Department at Sanford Underground Research Facility.
Flooding, the number-one type of natural disaster within the United States, poses risks to people, property and animals. Many people don’t understand the powerful force of flowing water or how rapidly they could be carried away. The number of flood related fatalities is equivalent to the combined deaths from hurricanes, tornadoes and being struck by lightning.
The NWS describes just how powerful rushing water can be: “A mere 6 inches of fast-moving flood water can knock over an adult. It takes just 12 inches of rushing water to carry away most cars and just 2 feet of rushing water can carry away SUVs and trucks. It is never safe to drive or walk into flood waters.”
Two thirds of these flooding-related fatalities occur while driving. Flowing water washes out roadways, culverts, bridges and safety barriers. Flowing water as little as two feet deep can wash away a full-size pickup or SUV. If, while driving, you encounter a section of flooded roadway that is underwater, turn around—don’t drive through it.
Children are often enthralled by flowing water and want to play in and around the newly discovered flows. Never allow children to be unattended around flood waters.
