National Dam Safety Program. Hilltop Fishing Lake Dam (MO 40064), Mississippi - St. Francis River Basin, Dunklin County, Missouri. Phase I Inspection Report.
Abstract
Hilltop Fishing Lake is an earthfill structure approximately 24.9 feet high and 1,500 feet long at the crest. The embankment has a horseshoe shape and forms three sides of the lake. The dam has no spillway or drawdown facility. Our inspection and hydrologic and hydraulic analyses indicate that the capacity of the dam meets the criteria set forth in the guidelines for a dam having the above size and hazard potential. The dam will hold and pass approximately 65 percent of the Probable Maximum Flood (PMF) without overtopping. The dam appeared to be in poor condition. Several deficiencies were noted during the inspection. The face of the embankment had varying slopes with some of them being rather steep. There are serious erosion problems on most of the dam, including shoreline erosion due to wave action. There are also numerous animal holes in the embankment. There is a poor vegetal cover on most of the dam. Another deficiency is the lack of seepage and stability analyses records.
