Book excerpt: The purpose of the 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. The inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillways will pass the 100-year frequency flood without overtopping the dam. The spillways will also pass 39% of the Probable Maximum Flood without overtopping the dam. The Probable Maximum Flood (PMF) is defined as the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region. Additional deficiencies, in accordance with the guidelines, are the lack of seepage and stability analysis. Deficiencies visually observed by the inspection team were trees and shrubs growing on both slopes, small rills and washes on both slopes, several rodent holes on the downstream slope, logs and trash lodged around the trash rack of the principal spillway riser and some erosion and/or sloughing along the east bank of the stilling basin.
