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.

Rainfall of one to three inches on frozen ground and into a snow pack with between 2 and 5 inches of liquid water equivalent resulted in considerable overland flooding.
