This report assesses the general condition of the dam with respect to safety, based on available data and on visual inspection, to determine if the dam poses hazards to human life or property. This dam has been classified as unsafe, non-emergency by the St. Louis District as a result of the application of the following criteria: (1) Spillway will not pass 50 percent of the Probable Maximum Flood; (2) Overtopping could result in dam failure; and (3) Dam failure significantly increases the hazard to loss of life downstream.

Waters Edge Estates Lake Dam is located in Boone County in the State of Missouri, and crosses the Hominy Branch tributary of Hinkson Creek. The dam was constructed to impound water for recreational purposes. The exposed embankment did not have adequate protective grass cover at the time of inspection. Small rivulets and minor shrinkage cracks were observed on the embankment. There is a cut at the downstream toe exposing a 5-foot high vertical face. The materials exposed in the cut face appear to be moderately plastic sandy clay overlaying the foundation soils and shale stratum. The upstream slope has no riprap protection or grass cover. Consequently, surface erosion of the loose surficial material has taken place. In addition, some minor wave erosion of the face has taken place. The dam material, exposed on the upstream face and removed from below the water line, appears to be light brown, moderately to highly plastic clay.
