National Program of Inspection of Non-Federal Dams, Tennessee. Glady Hollow Dam (OFDBA Site 41-1) (Inventory Number TN 13113), Obion River Basin, near Lassiter Corner, Tennessee, Obion County, Tennessee. Phase I Investigation Report.
Abstract
This report is based on the findings of a Phase I investigation of OFDBA Site 41-1 (Glady Hollow) Dam on February 4, 1981. This study was done in accordance with 'Recommended Guidelines for Safety Inspection of Dams', Department of the Army, Office of the Chief of Engineers. The earth dam is 32 feet high and 278 feet long with a crest width of 15 feet. It is in the small size and high hazard potential category. The structure impounds a 5.5 acre lake used for flood control. The embankment has moderate slopes 1V:3.4H upstream and 1V:2.8H downstream. No signs of uncontrolled seepage or distress was observed. A bare path has been cut into the downstream slopes by vehicles being driven up the slope. The remainder of the embankment has a well established grass cover. The principal spillway is a 24-inch CMP riser with an 18-inch CMP outlet. The drawdown facility is a 12-inch slide headgate located at the base of the riser. The emergency spillway is a 94-in wide grassed channel at the right abutment. It was in good condition and appears to have never carried flow. Analyses indicate that the spillway is adequate to pass the recommended 1/2 PMF. The dam is classified as 'deficient' due to the presence of an unvegetated area on the downstream slope.
