National Program of Inspection of Non-Federal Dams, Tennessee. Akers Dam (Inventory Number TN 16503), Barren River Basin, near Turners Station, Sumner County, Tennessee. Phase I Investigation Report
Akers Dam intercepts a small unnamed tributary of the Little Trammel Creek about one mile southeast of the Turners Station Community in Sumner County. The crest of the 26 foot high, earthfilled embankment is 11 feet wide and 280 feet long. The upstream slope is approximately 1V:1.4H and the downstream slope varies from 1V:1.5H to 1V:2.5H. The stability of the downstream face is questionable due to the steep slopes, extensive seepage, and emergence of the phreatic surface high on the downstream face. The reservoir discharges through a 23 foot wide saddle service/emergency spillway that is 150 long and located on the left abutment. Hydraulic analysis revealed the spillway to be marginally adequate to pass the 1/2 PMF, which is the design storm specified by the guidelines of the Office of the Chief of Engineers (OCE), for a dam in the small size and high hazard potential categories. At this time, the dam is considered unsafe-nonemergency. It is recommended that a qualified engineer be engaged immediately to determine modifications necessary for improving slope stability, seepage control, and determining condition of the drawdown drain along with moving the drawdown drain to the upstream end.
