National Dam Inspection Program. Tyrone Reservoir 2 (NDI ID535) Susquehanna River Basin, Sink Run, Blair County, Pennsylvania. Phase I Inspection Report.
Abstract
Based on the evaluation of the conditions as they existed on the dates of inspection and as revealed by visual observations, the condition of Tyrone Reservoir No. 2 is assessed to be poor and to require further investigation to evaluate the existing seepage conditions and appropriate measures for controlling seepage through the embankment. Field observations showed various seepages along the toe of the dam and the area below the toe of the dam was found to be swampy. Accumulation of silt at the seepage points on the sides of the outlet pipe headwall suggests internal erosion of the embankment. High and thick brush in the swampy areas below the toe of the dam precluded adequate visual inspection of these areas. This brush should be cut and removed to permit future visual inspections.
