National Dam Inspection Program. Colonial Dam Number 1. (NDI Number PA-00206, PennDER Number 26-12) Ohio River Basin, Allen Run, Fayette County, Pennsylvania. Phase I Inspection Report,
Abstract
Based on a review of available design information, engineering analyses, and visual observations of conditions as they existed on the date of the field inspection, the general condition of the Colonial Dam No. 1 is considered to be fair. This assessment is based on visual observations and hydrologic calculations that indicated: (1) that the earth embankment is in good condition, (2) that the principal spillways are in poor physical condition and have 'inadequate' capacity but are not 'seriously inadequate', and (3) the existence of non-serious deficiencies which are considered correctable. The structure is classified as a 'small' size, 'high' hazard dam. Corps of Engineers guidelines recommend 1/2 to one times the Probable Maximum Flood (PMF) for 'small' size, 'high' hazard dam. Colonial No. 1 Dam's Spillway Design Flood is 1/2 the Probable Maximum Flood (PMF).
