National Program of Inspection of Non-Federal Dams, Tennessee. Construction Products Dam (Inventory Number TN 11320), Middle Fork Forked Deer River Basin, near Carroll, Madison County, Tennessee. Phase I Investigation Report

摘要

The earth dam is 15 ft. high, 675 ft. long, and has a crest width of 13 feet. It is in the small size and high hazard potential category. The dam impounds a 5.5 acre lake used for recreation and water supply. The embankment slopes are moderate and have a well established grass cover. Vehicles have cut deep ruts into the crest. The principal spillway is a 36 inch diameter CMP riser with a 30 inch diameter CMP outlet. A slide headgate is located at the base of the riser to regulate the lake level. The emergency spillway is a irregular shaped earth channel at the left abutment. The channel is relatively flat and in good condition. The dam is classified as 'significantly deficient' because the spillway will not safely pass the recommended one-half Probable Maximum Flood.
