National Program of Inspection of Non-Federal Dams, Tennessee. Mary's Creek Dam Number 9 (Inventory Number TN 15739), Wolf River Basin, near Cross Roads, Shelby County, Tennessee. Phase I Investigation Report.
Abstract
The dam is a linear earthen structure 678 feet long and 23.7 feet high with a crest width of 10 feet. The upstream and downstream slopes are 1V:3.1H and 1V:3.OH respectively. The structure impounds a 10.5 acre lake at normal pool with 42 acre-feet of storage. At the top of the dam the pool area increases to 18 acres with an impoundage of 148 acre-feet. The drainage area is predominantly farmland, pasture, and woods. It has an average ground slope of approximately 5.7%. The embankment is well grassed and virtually free of undesirable vegetation. It has a relatively uniform cross section with well defined boundaries. Only minor erosion was observed on the embankment, along the upstream slope at the water surface and along the cattle trail traversing the dam.
