WOLF CREEK DAM FAILURE

I. HISTORY

Wolf Creek Dam/Lake Cumberland is located in the western part of Russell County, Kentucky,

approximately 150 miles northeast of Nashville, Tennessee. Construction was begun on the dam in 1938 and completed in 1950. Wolf Creek Dam is the largest dam east of the Mississippi River and is the ninth largest reservoir in the United States. The dam, located on the Cumberland River, has a shoreline of over 1,200 miles, and holds 6.1 million acre-feet of water (enough water to cover all of Kentucky with three inches of water).

The dam has been leaking since its construction, but recent changes along the dam have proven serious enough that the federal government to repair the dam has appropriated over 300 million dollars and dam engineers have seen fit to bring the leakage of the dam to public attention. Wolf Creek Dam is the worst rated dam in the US. The geology of the area resulted in the dam being built upon limestone (Karst’s Geology) that, after being mixed with water over time, has slowly eroded the rock and clay used to create the dam. Water is leaking through underneath the dam and forming sinkholes and wet spots on the riverside and also has resulted in over 4,000 feet of the 5,600-foot (lengthwise) sinking approximately three inches.

Repeated attempts to get actual numbers related to the projected water levels of Wilson County

from the Corps of Engineers (COE) have proven unsuccessful. Flood level estimates have ranged from 465 feet MSL (altitude measured from Mean Sea Level) to 492 feet. The closest flooding estimates for
