Flood in Clark County, South Dakota

A trained observer reported water over the gravel road north of Cottonwood Lake.

Slow moving low pressure generated a pocket of prolonged heavy rain over a portion of northeast South Dakota. Radar estimates of rainfall ranged between 2 and 5 inches in a broad area covering portions of Brown, Day, Clark and Codington counties, with public measurements of between 2.76 and 3.5 inches on the west side of Watertown, and an observed rainfall of 2.85 inches near Ferney. Portions of the Stokes-Thomas Lake City Park campground at Lake Kampeska experienced flooding as a result of this heavy rain. A trained spotter also reported water running over several roads 3 miles north of Bradley in Clark county. This heavy rain was also responsible for minor flooding along Mud Creek and the South Branch Tributary of Mud Creek both near Rauville.
