National Dam Inspection Program. Russellton Slurry Pond 3 (NDI Number PA 00839, Penn DER Number 2-52), Ohio River Basin, Tributary to Little Deer Creek, Allegheny County, Pennsylvania. Phase I Inspection Report
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 reservoir/spillway 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 3's 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 and/or improvement efforts.
