What happened

The episode as NWS ABR wrote it up.

As temperatures began to warm up towards the end of March, the near record to record winter snowpack over central, north central and northeast South Dakota began to melt and runoff, filling up ditches, lakes, creeks, streams, and low-lying areas. The massive amount of water, inundated hundreds of sections of county and township roads as well as several state and federal highways. The inundated sections of roads were either broken up or washed out. Tens of culverts were blown out or damaged and several bridges were either damaged or washed out by chunks of ice and the highwater flow. Thus, road closures were extensive with rerouting taking place for school buses, mail carriers, farmers, ranchers, etc.. Many spillways and dams received some damage or were washed out. Also, thousands of acres of farmland and pastureland were underwater. Due to the high groundwater, a countless number of homes received water in their basements. A few towns were partially flooded, including Twin Brooks in Grant County, Corona in Roberts County, and Raymond in Clark County. On March 27th, in the early morning hours, water flowed into Raymond filling the basements of several homes. In rural areas, several farms were surrounded by water and were inaccessible, leaving some people stranded and livestock marooned. Many other residences and businesses, mainly across northeast South Dakota, were threatened by highwater while others received significant damage or were a total loss. As a result, several people had to be evacuated. Many long-term residents said this was the most significant flooding they had seen in their lifetimes. The flooding continued into early to mid April.
