National Dam Inspection Program. Rosner Pond Dam (NDI ID Number PA- 01111, DER ID Number 64-190), Delaware River Basin, Tributary to West Branch Lackawaxen River, Wayne County, Pennsylvania. Phase I Inspection Report
Abstract
The visual inspection and review of available data indicate that Rosner Pond Dam is in poor condition. The lack of a spillway and the poor condition of the outlet works 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 1/2 PMF to full PMF. Based on the size of the dam and degree of Downstream hazard, the selected SDF is the 1/2 PMF. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and outlet works discharge capacity will not pass the SDF (1/2 PMF) prior to overtopping the embankment. Under present conditions, the discharge/storage capacity is 11% of the PMF prior to overtopping. In accordance with the criteria outlined and evaluated in the discharge capacity for Rosner Pond Dam is considered to be seriously inadequate. The dam in its present condition is considered to be unsafe, non-emergency.
