Abstract:

Based on a review of available information, visual observations of conditions as they existed on the date of the field inspection, and supporting engineering calculations, the general condition of the Russellton Slurry Pond 3 is considered to be fair. This assessment is based primarily on visual observations of the embankment, spillway and seepage conditions and hydrology hydraulic analyses of reservoirspillway capacity. The structure is classified as a large size, high hazard structure. Corps of Engineers guidelines recommend the Probable Maximum Flood PMF as the Spillway Design Flood for a large size, high hazard dam. Pond 3s 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. The Phase I investigation of Pond 3 revealed deficiencies and conditions which should be corrected or improved through implementation of the following recommended remedial, monitoring andor improvement efforts.
