National Dam Inspection Program. Blue Head Dam (NDS ID Number PA-678, DER ID Number 54-37) Susquehanna River Basin, Negro Hollow and Messer Runs, Schuykill County, Pennsylvania. Phase I Inspection Report,
Abstract
The assessment of Blue Head Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. Blue Head Dam appears to be in fair condition. The erosion on the crest and upper portions of the slopes should be repaired. In addition, the wet areas and seepage areas should be monitored on a regular basis. Maintenance of the dam and operating facilities is considered poor. Blue Head Dam is a high hazard-small size dam. The recommended Spillway Design Flood (SDF) for this dam is the 1/2 PMF to PMF. Based on the potential for downstream loss of life, the SDF has been selected as the PMF. The spillway and reservoir are capable of controlling approximately 25% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. If Blue Head Dam should fail due to overtopping, the hazard to loss of life and property immediately downstream of the dam would be significantly increased from that which would exist prior to the overtopping. Blue Head Dam is classified as unsafe non-emergency.
