Abstract:

This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. The examination of available engineering documents and visual inspection of the Conewango Creek Watershed Project - Site 33 dam did not disclose conditions which constitute a hazard to downstream human life or property. The total discharge capacity of the combined principal and auxiliary spillways is adequate to impound and safely discharge the floodwater resulting from the Probable Maximum Flood PMF. A number of minor deficiencies were noted on this structure. These deficiencies include debris around the trash racks of the orifice in the riser intake structure, debris logs on the lower half of the upstream slope as measured from the crest to the normal pool elevation, slight erosion along abutment- embankment contacts on lower third of downstream slope, damaged internal drainage pipes above plunge pool, small animal burrow on downstream slope just above riprap around the principal spillway outlet pipe, wet areas beyond downstream toe in waste area along east side of outlet channel and natural flood plain on the west side of the outlet channel.
