On June 22, National Weather Service was showing thirteen stream gauges at major flood stage in South Dakota and Iowa and twenty-seven over a broader area that extended southeastward toward Indiana.
Flooding in March and April was significant. Central South Dakota farmers suffered from floods along the James and Big Sioux rivers, as well as rising lakes. Ice jams along the White River in south central South Dakota forced evacuation of farms and homes. The northeast corner of the state also was heavily impacted, and anticipates a Federal declaration.
In North Dakota, the Red River crested lower than had been predicted and flood-fight efforts were largely successful. South Dakota is preparing for increases in West Nile Virus as a result of the floods. South Dakota Extension facilities were not impacted.
Kim Cassel (SD) used EDEN and eXtension flood resources to enhance a local preparedness web site that is an off-shoot of the state Extension preparedness site. The hit-rate doubled during the flood emergencey. The Brookings County Emergency Manager shared the EDEN/eXtension flood resources with state emergency management officials and the information went directly to their IT folks for use in the local and state EOCs.
The EDEN publication First Steps to Flood Recovery had been distributed previously in South Dakota to county Extension and Emergency Management offices. The publication was re-ordered in 2010 and more copies distributed to flood prone areas of the state. The audio files of this publication were posted to the web page and shared with emergency management.
April brought rain, also, to some Northeast states in amounts that have not been seen in 200 years. Flooding was widespread and Presidential declarations for those floods were announced. "Northeast Floods April 2010" was added to the Response Notes system
