March 15, 2010:

Snowmelt runoff from an expansive snow cover flooded many rivers, creeks, roads, along with thousands of acres of pasture and cropland throughout northeast South Dakota. There were numerous road closures. The flooding lasted through the end of the month and for many locations into April. The counties mainly affected were Brown, Marshall, Day, Spink, and Roberts. Numerous communities were affected including Aberdeen, Claremont, Waubay, Amherst, Kidder, and the Richmond Lake area. The Claremont, Amherst, and Britton areas were the hardest hit with flooded land and roads. Several farms were surrounded by water with some people stranded. Between Aberdeen and Britton, sixty percent of the land was under water. Thousands of acres of cropland will not be planted due to too much water with estimates that 20 to 25 percent of Brown county cropland would not be planted. Many people in northeast South Dakota have had too much water for many years. The road damage was extensive and repairs will be in the millions of dollars. Many roads across the area will also have to be raised. Many people had extra long commutes due to flooded roads with some people having to move out of their homes. Across Day and Marshall counties, rising lakes threatened many homes and cabins with sandbagging taking place. Most lakes and rivers across northeast South Dakota were at or near record levels.
