National Dam Safety Program. Rockwood Hills Lake Dam (MO 30372), White River Basin, Taney County, Missouri. Phase I Inspection Report.

Abstract : The purpose of this inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. This dam is in the high hazard potential classification, which means that loss of life and appreciable property loss could occur if the dam fails. The inspection and evaluation indicate that the combined spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The embankment was in poor condition. Deficiencies visually observed by the inspection team were: (1) sloughing along crest of dam; (2) Large slough along toe near end of emergency spillway; (3) Erosion on upstream face, i.e., no wave protection; (4) Steep downstream discharges; (6) Heavy brush and weed growth on embankment faces; (7) Animal burrows on front face; (8) Erosion between spillways and embankment; and (9) Undermining of ends of both spillway chutes. Another deficiency was the lack of seepage and stability analysis records. It is recommended that the owners take the necessary action immediately to correct the deficiencies reported herein.
