32.5 Highway 160 will be inundated with around 2 feet of flood waters east of Oswego from around the Neosho River Bridge spreading outward along the floodplain. Expect road closures and farmland flooding.
30 Highway 160 will be covered with about 4 inches of flood waters starting from the Neosho River Bridge in Cherokee County and may spread outward along the floodplain 1.5 miles west toward Oswego until the rise in elevation. Flood waters threaten to enter the overflow pipe to freshwater container at the water plant.
