In 1978, severe flooding throughout the State of Kentucky occurred from December 3-10 as a result of intense precipitation from two storms. The storms of December 3-5 and December 7-10 produced record peak discharges in several areas throughout central and eastern Kentucky, resulting in damages of nearly 50 million dollars and the loss of five lives. This report summarizes data collected during the floods by the U.S. Geological Survey, Water Resources Division, and other Federal and State agencies in Kentucky. The data include precipitation, streamflow, and water-quality data (including suspended sediment). Estimates of property damages in selected basins are also provided. The information is preliminary and subject to revisions. (Woodard-USGS)
