Based on a review of available design information, visual observations of conditions as they existed on the date of the field inspection, and supporting calculations, the general condition of Robena Slurry Pond 6 is considered to be good. The structure is classified as a large size, significant hazard dam. Corps of Engineers guidelines recommend the Probable Maximum Flood PMF as the spillway Design Flood for a large size, significant hazard dam. Robena Slurry Pond 6s Spillway Design Flood is the Probable Maximum Flood. Spillway capacity is adequate because the non- overtopping flood discharge was found, by using the HEC-1 computer program, to be in excess of 100 percent of the PMF. No emergency operation and warning plan was found for the facility. The field inspection indicated very minor deficiencies which can be corrected or improved as a part of normal maintenance efforts.
