Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Curtis Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The existing spillway can pass 17 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The resulting outflows from the failure of Curtis Dam would probably overtop and cause the failure of Emlhurst Dam. This would result in the loss of life. As a whole, the dam is judged to be in fair condition. If the low areas of the top of the embankment were raised 1.1 feet to the design elevation and if the low areas of the dike were raised 2.0 feet to the design elevation, the spillway could pass 46 percent of the PMF. The spillway capacity would still be rated as seriously inadequate. There is no evidence of stability problems on the embankment. The spillway and auxiliary spillway sections meet the OCE guidelines for stability. A length of the left spillway training wall has failed.

Based on visual inspection, available records, calculations, and past operational performance, and according to criteria established for these studies, No. 5 Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The spillway can pass 29 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. Failure of the dam would cause an increase hazard to loss of life downstream. As a whole, the dam is judged to be in fair condition. The spillway gravity weir does not have any significant deviations from the guidelines for stability, since the toe pressure is well below the allowable. There is no evidence of instability on the embankment.

This report is prepared under guidance contained in the Recommended Guidelines for Safety Inspection of Dams, for Phase I Investigations. The purpose of the Phase I investigation is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general condition of the dam is based upon available data and visual inspections. Detailed investigation, and analyses involving topographic mapping, subsurface investigations, testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify any need for such studies. In reviewing this report, it should be realized that the reported condition of the dam is based on observations of field conditions at the time of inspection along with data available to the inspection team. In cases where the reservoir was lowered or drained prior to inspection, such action, while improving the stability and safety of the dam, removes the normal load on the structure and may obscure certain conditions which might otherwise be detectable if inspected under the normal operating environment of the structure.

Based on visual inspection, available records, calculations and past operational performance, Dunmore No. 1 Dam is judged to be in good condition. The spillway can pass 84 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. Two culverts, immediately downstream of the dam, may provide significant tailwater effects at the dam. If the top of the dam were raised 0.4 foot to its design elevation, the spillway can pass 90 percent of the PMF. The spillway capacity would still be rated as inadequate. Because there is no analysis available, the structural stability of the masonry gravity spillway is unknown. The spillway right training wall does not have any significant deviations from the guidelines for stability. There is no evidence of instability on the embankment.

Based on visual inspection, Coleman Dam is judged to be in poor condition. In the absence of a spillway, the dam is subject to frequent overtopping. Based on the downstream hazard and in accordance with the recommended guidelines, the minimum selected Spillway Design Flood (SDF) for the facility is the 100-year flood. Results of the hydrologic and hydraulic analysis indicate that the peak discharge of the 100-year flood is 200 cfs. The existing facility will not pass the 100-year flood without overtopping the dam. Although the dam has withstood frequent overtopping since its construction, the maximum depth of past overtopping could not be verified. Therefore, in the absence of a spillway and based on the downstream hazard, the facility is rated inadequate. Although there is significant leakage and seepage through the dam, the available information is insufficient to evaluate its structural stability. The Dam is not properly maintained, as evidenced by the heavy growth of trees on the embankment and the numerous burrows on its downstream slope. (Author).

Based on visual inspection, available records, calculations and past operational performance, Lake Henry Dam is judged to be in good condition. The existing spillway can pass 60 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. If the embankments were raised 0.7 foot to their design elevation, the dam could pass the PMF with 0.05 foot of freeboard. The spillway capacity would then be rated as adequate. A low area between the two embankments acts as an auxiliary spillway. There is no stability analysis for the embankments. There is no evidence of significant problems threatening the embankments. The spillway weir is judged to be stable.

Fords Lake Dam is located on Buttermilk Creek in Newton Township, Lackawanna County, one-half mile north of Schultzville, Pennsylvania. Purpose of Dam was for public fishing. The overall appearance of the dam is very poor. Deficiencies observed during the field inspection are illustrated on the General Plan. The profile and typical sections of the dam are presented and are based on field survey made the day of the inspection. On the inspection date (12/08/80), the lake level was at elevation 1146.8, about 0.2 foot below spillway crest. Pertinent features observed are shown in photographs.
