Overview

Repeated rounds of moderate to heavy rainfall across the entire Ohio River basin totaled between 8 to 9 inches along and on either side of the Ohio River from February 15 to March 1. These totals were 200 to 400% above normal values for mid to late February. The large areal extent of the excessive rainfall led to significant rises on area rivers, including the Ohio River. This was the biggest flood on the Ohio River in Louisville since March 1997.
