What the reports say
Written by National Weather Service staff at the time of the event · public domain
Flooding resulted in some crop loss and extensive damage to public infrastructure including numerous county and township roads, culverts, and some bridges. The property damage costs include estimates for public property losses. Crop loss estimates provided by the United States Department of Agriculture.
After excessive two-day rainfall during September 10-12 (6.57 inches near Aurora, 6.55 inches 3 miles west southwest of Brookings, 6.27 inches 8 miles south of Brookings), the Big Sioux River near Brookings (gage site BRKS2) reached the second highest stage on record of 5.39 feet above flood stage on September 13. Numerous county roads and bridges were inundated, with a few farm outbuildings engulfed in water. Agricultural flooding was extensive.
Major flooding of the Big Sioux River, as well as flooding of lakes and lowlands in the county, continued through April, though small stream flooding abated and flooding in other areas such as the city of Flandreau abated some. Some farmland remained flooded, both near to and away from the Big Sioux River. A few roads remained closed by the flooding for part of the month. Water was covering some other roads, mainly from flooded lowlands. Some roads were damaged. 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.
