What the reports say
Written by National Weather Service staff at the time of the event · public domain
Street flooding in numerous intersections within the city of Yankton. A high number of flooded basements also reported, especially along Marne Creek. Other flooding resulted in extensive damage to public infrastructure including numerous county and township roads, culverts, and some bridges.
Flooding continued from August, but the James River near Yankton (YNNS2) soon fell below flood stage on September 4. However, excessive rainfall of 4 to 8 inches upstream September 10-12 (7.54 inches at Mitchell and 7.21 inches 7 miles south of Parkston) led to a rapid rise and a record crest 15.1 feet above flood stage on September 14. Five of the six bridges crossing the James River in Yankton county were closed. Innumerable roads were inundated and closed for several days, including major roadways of Highway 81 north of Yankton and Highway 46 west of Irene. Extensive amounts of agricultural land were inundated. Fifty-five homes were impacted by flood waters in Yankton county, with residents forced to take temporary shelter until floodwaters receded. Minor flooding continued at the end of the month.
Major flooding of the James River, as well as flooding of small streams and lakes in the county, continued through April. Much farmland remained flooded, both near to and away from the James River. The James River was 9.2 feet above flood stage near Yankton April 1st, and fell very slowly during the month. A large area of land and numerous roads were flooded at the start of the month. Water was running over other roads, from flooded streams, creeks, and fields as well as from the James River. Many roads were heavily damaged. Some homes and businesses were also flooded, with the flooding of these places slowly alleviating through the month. High water and groundwater levels from record precipitation in the year 2010, a main reason the flooding onset was so fast in March, was also a main reason that the flooding subsided so slowly during April.
