National Dam Inspection Program. Hamlin Lake Park Dam (NDI ID Number PA- 1014, DER ID Number 42-17), Ohio River Basin, Marvin Creek, McKean County, Pennsylvania, Borough of Smethport. Phase I Inspection Report
Abstract
The assessment of Hamlin Lake Park 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. Hamlin Lake Park Dam is a high hazard-small size dam. The recommended spillway design flood (SDF) for a dam of this size and classification, is in the range of 1/2 PMF to PMF. Based on the height of dam, storage capacity of the reservoir, and flow capacity of Marvin Creek the spillway design flood has been selected as the 1/2 PMF. Hamlin Lake Park Dam is capable of controlling approximately 9% of the PMF without overtopping the earthen embankment section. The breach analysis and downstream routing of the flood wave does not indicate an increased potential for loss of life from that which existed just prior to failure of the dam due to overtopping. Therefore, the spillway is termed inadequate, but not seriously inadequate.
