Repairs on the U.S. Army Corps of Engineers' most closely monitored dam will soon resume now that the reasons for movement in the earthen portion of the dam have been determined, reports The Times Journal of nearby Russell Springs. A concrete curtain is being installed in the earthen portion to stop leaks caused by the erosion of karst limestone under the dam, which impounds 101-mile-long Lake Cumberland.

UPDATE, Nov. 18: The Times Journal reports that the Corps has changed its construction techniques in the troublesome area, the earthen portion of the dam that adjoins the concrete portion. "A six-month study showed the movements were not the result of deep-seated sliding of the embankment, but rather shallow movements attributed to several other causes," the newspaper reports. The change probably means that repairs to the dam, and return of the lake to its normal water level, will be delayed. "the Corps will negotiate contract modifications over the next few months, officials said. The contractor will begin to procure the necessary equipment and casing which will be fabricated and mobilized to the site over a period of five to eight months," The Times Journal reports.
