National Dam Inspection Program. Longford Lake Dam (NDI ID Number PA- 00898, DER ID Number 58-137), Susquehanna River Basin, Tributary to Choconut Creek, Susquehanna County, Pennsylvania. Phase I Inspection Report
Abstract
The visual inspection and review of available design and construction data indicate that Longford Lake Dam is in good condition. In accordance with the guidance provided, the spillway design flood (SDF) ranges between 1/2 the PMF and the full PMF. Based on the size and extent of downstream hazard for the dam, the SDF selected for this facility was the PMF. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass 88% of the PMF prior to overtopping the embankment. Therefore, in accordance with the recommended criteria for Phase I inspections, the spillway for Longford Lake Dam is considered to be inadequate.
