Rainfall totals from across the county included: 3.32 inches at Ashland; 3.46 inches at Jeromesville; 5.18 inches at Mifflin and 4.02 inches at Loudonville.

Many homes and businesses along and near the river sustained flood damage. Hundreds of other homes in the county suffered damage, mainly from basement flooding. Finally, standing water and erosion from the runoff caused damage to agricultural interests in the county.
