BEST ADVICE WHEN IT COMES TO PADDLING IN FLOODWATERS: DON'T

Provided by NOOA
Record-breaking flooding has submerged parts of the Midwest this past month. According to reports, the flooding along the Missouri River and its tributaries have caused at least $3 billion damage and forced thousands from their homes as floodwaters penetrated or flowed over several hundred miles of levees.
Though some of the floodwaters are receding, the forecast for significant spring rains and snow runoff continues to put flood fighters on alert.

“The flooding this year could be worse than anything we’ve seen in recent years, even worse than the historic floods of 1993 and 2011,” said Mary C. Erickson, deputy director of the National Weather Service, in a conference call with reporters. The major flooding this month in Nebraska, Minnesota, Iowa and elsewhere is “a preview of what we expect throughout the rest of the spring.”

Flood waters are very unpredictable. Each year, more deaths occur due to flooding than from any other thunderstorm related hazard. The Centers for Disease Control and Prevention report that over half of all flood-related drownings occur when a vehicle is driven into hazardous flood water.
Most people underestimate the force and power of water. A mere 6 inches of fast-moving flood water can knock over an adult. It only takes a foot of rushing water to sweep away a small car, while 2-feet of rushing water can wash away most vehicles along with the road under it.

Last week, the Nebraska Game and Parks Commission sent out a plea to urge the public to stay off of rivers affected by recent flooding. Those who wish to canoe or kayak should wait until water levels recede or plan a trip on water bodies that did not experience flooding.

Our best advice we can give when it comes to paddling in flood waters is: DON'T!
Why would you even consider boating in a river, creek or any other body of water is at or above flood stage? You are not only risking your life but the lives of search and rescue crews, not to mention the possibility of arrest and fines if law officials issue orders banning all nonofficial watercraft in the flooded areas.

NRS listed eight dangers in flood stage boating in their web page article entitled Riding the Flood, that should always be considered before paddling in inundate waters

  • Debris in the water. The rising water pulls streamside debris into the flow. Banks get undercut and trees, fence posts, and structures fall into the water. You can find yourself sharing the run with all sorts of foreign objects.
  • Strainers. Trees and logs get lodged and create severe hazards. Water flows through and around them; you and your boat won’t. In larger streams, you may be able to avoid them. In a smaller stream, a strainer can completely block it. Undercut rocks and boulder sieves are also severe entrapment hazards that can be created or accentuated by high water.
  • Low head dams. A low head or “run of the river” dam is used to raise the level of a stream. Water flows over the lip of the dam and creates a perfect reversal on the downstream side that can go from difficult to impossible to get out of. They are dangerous at any flow but can be particularly strong at high flows.
  • Bridge abutments. They can catch debris and even block off the channel. Even without debris catch, they kick off big swirling side-curling waves.
  • Turbid water. The muddy flow hides hazards that would normally be visible.
  • Water out of its banks. The stream can flow out into the surrounding countryside, taking you into trees, brush, fences and other entrapment obstacles.
  • Cold water. Especially in the spring, cold water significantly increases the risk of hypothermia.
  • Fast current. Normally, the higher the water, the faster it is flowing. Things happen fast, you have much less time to react to conditions.

  1. Already we have record-breaking flooding across the Midwest and with the potential of more spring rains to come it looks like there will be more high water to come. This week in Outside Adventure to the Max, our best advice when it comes to paddling in these flooded waters is: DON'T
