National Dam Inspection Program. Griffin Dam (NDI PA-035, PA-455), Susquehanna River Basin, West Beechwood Run, Tioga County, Pennsylvannia. Phase I Inspection Report.

摘要

Based on a visual inspection, past performance, and available engineering data, the facility is considered to be in excellent condition. The emergency spillway is capable of discharging the peak inflow resulting from a storm of PMF intensity, as determined by the Corps of Engineers (HEC-1) procedures, and is thus considered adequate. The adequacy of the seepage control measures, which could be considered minimal, should be observed and evaluated during higher pool or flood conditions. It is recommended that the operation and maintenance procedures listed in the owners' operation and maintenance agreement be formalized into a manual and kept available to ensure the continued proper care of the facility. Provision should be made to include a formal warning system to provide for and establish procedures to protect the lives and property of downstream residents during emergency conditions.
