2001: Heavy rain of 1 to 3 inches, combined with snowmelt runoff, brought flooding to parts of northeast South Dakota. Many roads across Clark, Grant, Hamlin, Deuel, and Roberts counties were flooded and damaged. Floodwater moving towards the town of Willow Lake overpowered culverts and flooded several homes and several streets. Highway 28 had to be cut through to allow the water to flow away from the town, averting a disaster. Highwater from the creek west of Corona in far Southern Roberts county flowed towards Corona. As a result, 3 1/2 feet of water coursed through town flooding several homes and streets and knocking out the sewer system. Also, 1000 feet of railroad track was damaged by the floodwaters. The Big Sioux River and Lake Poinsett in Hamlin county also rose and resulted in some agricultural land and road flooding. The heavy rain and snowmelt also brought flooding throughout Codington county, especially in the Watertown area along the Big Sioux River and at Lake Kampeska. Many roads, especially gravel roads, throughout Codington county were flooded and damaged. The Big Sioux River near Watertown rose to 11.5 feet, 2.5 feet above flood stage, with Lake Kampeska rising to around 4 feet overfull. As a result of the flooding on the Big Sioux River, 300 people in Watertown were evacuated and were not allowed to return until the 22nd. Also, several streets were closed in Watertown due to the flooding. Hundreds of National Guardsmen, volunteers, prison inmates, and city and emergency crews sandbagged along the Big Sioux River and Lake Kampeska to divert any flooding. A bridge on the Big Sioux River buckled due to large pieces of ice slamming into it. As Lake Kampeska rose, nearly 100 homes had to be evacuated along with 3 major businesses. 30 homes and 2 businesses along the lake were flooded resulting in extensive damage. Lake Pelican also rose to way overfull, flooding several homes and roads.
