National Dam Inspection Program. Interlaken Dam (NDI ID Number PA-01037, DER ID Number 35-087), Susquehanna River Basin, Tributary to Summit Lake Creek, Lackawanna County, Pennsylvania. Phase I Inspection Report
Abstract
The Visual inspection and review of available design and construction data indicate that Interlaken Dam is in poor condition. The deteriorated condition of the spillway, the inadequate spillway capacity and the adjacent breached and low areas of the embankment are the primary deficiencies which cause concern for the safety of this facility. In accordance with the recommended guidelines, the spillway design flood (SDF) for this facility is in the range of the 100 year flood to 1/2 the Probable Maximum Flood (PMF). Based on the size of the dam and degree of downstream hazard, the selected SDF is the 100 year flood. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will not pass the SDF (100 year flood) prior to overtopping the embankment. In accordance with the criteria outlined and evaluated in Section 5.5, the spillway for Interlaken Dam is considered to be inadequate. (Author)
