National Program of Inspection of Non-Federal Dams, Tennessee. Reed Lake Dam Number 2 (Inventory Number TN 16707), Loosahatchie River Basin, near Millington, Tipton County, Tennessee. Phase I Investigation Report,

Abstract

Reed Lake Dam No. 2 has a 10.1 acre lake and is located in Tipton County, Tennessee approximately one mile north of the Shelby County line and one mile west of Highway 51, and is an earth fill embankment 14 feet high and 320 feet long and the crest width is ten feet. Facilities for discharge from the reservoir are located in the right abutment and consists of two cuts in the abutments. The new spillway has a bottom and top width of 15 feet and 47 feet respectively and the old spillway has a bottom and top width of 12 feet and 33 feet respectively. The combined discharge is 149 cfs. The embankment slopes are 1V on 2H on the upstream slope and 1V on 1H on the downstream slope. Both upstream and downstream slopes have undesirable vegetation. Reed Lake Dam No. 2 is in the small size category and has a downstream hazard potential classification of high by the Corps of Engineers and I by the State of Tennessee. On the basis of hydraulic analysis, Reed Lake Dam No. 2 flood storage (15 acre-feet) and spillways are inadequate to safely pass the 1/2 Probable Maximum Flood (PMF), which Office of the Chief of Engineers (O.C.E.) Guidelines specify to be the design flood for a dam in the small size and high hazard categories. The dam is considered 'Unsafe-Non-emergency'.
