Progress Update: Downstream Berm Construction Underway

Some 62,000 tons of stone has been placed at Boone Dam as construction continues on both sides of the earthen embankment. While activities on the upstream side of the dam are visible to boaters and neighbors, extensive work is now taking place on the less-visible, downstream side of Boone Dam. Some instruments were relocated to the downstream side and new construction is adding stability before work begins on the underground cutoff wall. TVA engineers are taking all recent data into consideration as they complete final design of the cutoff wall.

A diagram of the proposed diaphragm wall shows how it will help strengthen Boone Dam against erosion or seepage under the embankment.

Extensive work is taking place within a very small area on the downstream side of Boone Dam. Heavy equipment can be seen pushing small aggregate uphill.
