Orson Pond Dam is classified as a 'Significant' hazard - 'Small' size dam. The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will not pass the 100-year flood without overtopping the dam. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Orson Pond Dam. Because the dam is on the low end of the 'Small' size category in terms of storage capacity and height, the 100-year flood was chosen as the SDF. During the 100-year flood, the dam is overtopped by a maximum depth of 1.79 feet for a total duration of 9.33 hours. The spillway is therefore considered 'inadequate.' It is recommended that the owner immediately develop recommendations for remedial measures to reduce the overtopping potential of the dam. Several items of remedial work should be immediately initiated by the owner.

Beaver Pond Dam is classified as a 'Significant' hazard - 'Small' size dam. The dam was found to be in poor overall condition at the time of inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will not pass the 100-year flood without overtopping the dam. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Beaver Pond Dam. Because the dam is on the low end of the 'Small' size category in terms of storage capacity and height, the 100-year flood was chosen as the SDF. During the 100-year flood, the dam is overtopping by a maximum depth of 3.27 feet for a total duration of 8.67 hours. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately develop recommendations for remedial measures to reduce the overtopping potential of the dam.
National Dam Inspection Program. Hathaway Pond Dam (NDI ID Number PA 00050, PennDER Number 58-06), Susquehanna River Basin, West Branch of Lackawanna River, Susquehanna County, Pennsylvania. Phase I Inspection Report

Hathaway Pond Dam is located in Ararat Township, Susquehanna County, Pennsylvania. The reservoir was originally created to provide water for power purposes. The reservoir slopes are moderate with a good cover of vegetation. There are three ponds upstream from Hathaway Pond Dam on two tributary streams. The western stream contains Romobe Lake (PennDER I.D. No. 58-10) which is 1750 feet upstream from Hathaway Pond Dam. The eastern tributary contains Ball Lake and an unnamed smaller pond in series. Ball Lake is 2450 feet upstream and will retain considerable storage while the smaller unnamed pond was considered to have no effect on Hathaway Pond Dam. Two homes, a trailer, and township road are located 1800 feet downstream from Hathaway Pond Dam. These could suffer economic damage in the event of a dam failure.

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.

The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway capacity is less than the peak inflow to the impoundment during the 100-year flood. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Steinhauer Dam. Because the dam is on the low end of the 'Small' size category in terms of storage capacity and height, the 100-year flood was chosen as the SDF. The spillway will not pass the SDF without overtopping the dam. The spillway is therefore considered inadequate.
