National Dam Inspection Program. Crabapple Dam (NDI Number PA 00907, PennDER Number 26-32) Ohio River Basin, Crabapple Run, Fayette County, Pennsylvania. Phase I Inspection Report,

Abstract

Based on a review of available design information and visual observations, the general condition of the Crabapple Dam is considered to be poor. Visual observations and hydrology calculations indicate: (1) A possible inadequate margin of safety against slope failure as indicated by slope irregularities and groundwater conditions; (2) 'Inadequate' discharge capacity of the Principal Spillway as determined by using HEC-1 Dam Safety Version computer program; and (3) The lack of accessible control facilities on the outlet works pipelines.
