National Dam Inspection Program. Sugar Creek Dam (NDI ID Number PA-728, DER ID Number 8-53), Susquehanna River Basin, South Branch Sugar Creek, Bradford County, Pennsylvania. Phase I Inspection Report
The assessment of Sugar Creek 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. The inspection and review of Sugar Creek Dam did not reveal any problems which would require emergency action. The dam appears to be in fair condition and in need of minor maintenance. The Sugar Creek Dam is a high hazard-small size dam. The spillway design flood (SDF) for a dam of this size and classification is 1/2 PMF to PMF. The PMF has been selected as the spillway design flood based on the downstream potential for loss of life. The spillway and reservoir are considered capable of controlling approximately 50% of the PMF. The 0.1 feet of overtopping of the embankment crest during the 1/2 PMF event for a duration of 1 hour was not considered sufficient to cause failure of the structure. Based on the judgement of the evaluating engineer, the location and duration of the overtopping as well as the existence of a concrete curb on the upstream and downstream edge of the embankment crest would sufficiently contain the overtopping to the spillway area minimizing damage to the embankment and spillway. The spillway is considered inadequate.
