6. Ocheyedan River
Major flooding is expected this spring on the Ocheyedan River in Iowa. The river is a tributary of the Little Sioux River, and flows 58 miles. Northwest Iowa communities such as Cherokee, Spencer, Rock Rapids, Akron, Hawarden, and Linn Grove were under flood warnings in mid-April from the National Weather Service.
7. Little Sioux River
NOAA predicted major flooding along much of the Little Sioux River in Iowa this spring. Last month, the National Weather Service reported record river heights for seven areas in northwest Iowa, and parts of southeast South Dakota. In the town of Cherokee, the Little Sioux River rose to a record 28.4 feet, or more than 11 feet above flood stage. Iowa Gov. Kim Reynolds issued a disaster proclamation on March 14 for 15 counties, bringing the total counties eligible for emergency relief to 21.
8. Big Sioux River
Major flooding was also forecast for the Big Sioux River, a 419-mile long tributary of the Missouri River, in eastern South Dakota and northwestern Iowa. Last month, Sioux City emergency-response officials who had been concerned Big Sioux waters would approach historic levels were more optimistic that flooding would not be as catastrophic as the flood 50 years ago, when the town of North Sioux City was evacuated.
9. Wood River
In Nebraska, major flooding is expected from the Wood River this spring. In mid-March, the Wood River surged above flood stage in the city of Wood River before receding. Hall County and the city of Wood River planned to seek money from the governor’s emergency fund to recover from damage done by last week’s blizzard and the flooding which followed.
10. Shell Creek on the lower Platte
Major flooding is forecast this spring at Shell Creek on the lower Platte River. In Nebraska earlier this spring, a gap in a levee along Shell Creek prompted the National Weather Service to issue a flash flood warning for the towns of Schuyler and Rogers. A recent spring flood outlook report by the National Weather Service listed Shell Creek and Logan Creek at “much-above-normal” risk for flooding.
