Grant County Flood History

Flood — Mar 28, 2019

The winter snow melted first across portions of Grant, Wilkin, and Clay counties. Visible satellite imagery confirmed this fact, showing a distinct snow free north to south band that extended roughly 20 or so miles east of the Red River in these three counties. As the snow melted, it flooded low lying areas and roads. Numerous sections of land pooled with water from the snow melt.
