Little Bear Creek Dam Seepage Statement

February 2018

TVA has completed the initial phase of investigation of seepage at Little Bear Creek Dam and is currently operating at a lake level of about 609 feet above sea level, which is within the normal winter pool operating guide.

This first phase of investigation confirmed that the spillway subgrade has not been degraded by seepage or loss of supporting soil. Additionally, the investigation identified potential seepage paths within the dam’s bedrock foundation.

TVA continues to monitor the dam and is now installing instruments and conducting preparatory work for phase 2 of the investigation. This will involve subsurface drilling around the dam spillway to be conducted in March and April. This second phase of work is expected to be completed in May 2018.

The work will be sequenced to minimize impacts on lake levels. The reservoir levels are expected to return to normal summer pool (about 620 feet above sea level), depending on rainfall and weather, by the regular summer operating schedule.
