Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in fair condition. The size classification of the facility is small and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Due to the high potential for damage to downstream structures and possible loss of life, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store approximately 50 percent of the PMF prior to embankment overtopping at the low area in the embankment crest. Consequently, the spillway is assessed as being inadequate, but not seriously inadequate. Recommended owner procedures are listed.

Panther Lake Dam is a homogeneous, earthfill embankment. It is about 19 feet high at its maximum section and is 665 feet long, including the spillway. The embankment is founded on earth. The spillway is located at the right abutment and consists of an approach channel, a concrete weir, a stilling basin, and an outlet channel. The crest length is 67.2 feet. The spillway crest is 4 feet lower than the top of the dam. The outlet works is located at the maximum section of the embankment and consists of an intake structure, a 30-inch diameter reinforced concrete conduit, and an outlet structure. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Panther Lake Dam is judged to be in good condition. The spillway will pass about 60 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. No stability problems were evident for the embankment or the appurtenant structures at the time of the visual inspection.

Based on a visual inspection, operational history, and hydrologic and hydraulic analysis, the dam is considered to be in fair condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (probable Maximum Flood) and the PMF. Since the facility is classified near the upper bounds of the small category with regard to available storage capacity, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate that under existing conditions the facility will pass and/or store only about 17 percent of the PMF prior to embankment overtopping at the low area adjacent the left abutment. If the low area were regraded to the design top of dam, the spillway system would then pass about 28 percent of the PMF prior to embankment overtopping. Under existing conditions, spillway discharges are controlled by the existence of a township-owned roadway embankment and culvert that is situated about 100 feet downstream of the spillway weir.

The purpose is to determine if the dam constitutes a hazard to human life or property. Beaver Lake Lodge Dam is located on Raymondskill Creek in Milford Township, Pike County, Pennsylvania. The visual inspection of the facility suggested that the dam and its appurtenances are in poor condition. The overall appearance of the facility suggests it to be in poor condition. Remedial measures are necessary to: (1) repair to deteriorated concrete spillways, (2) remove the trees and overgrowth from the embankment crest and slopes, (3) provide adequate erosion protection along the downstream embankment toe, and (4) restore the operability of the outlet conduit, or provide an alternate means of reservoir drawdown.

Wild Acres Lake Dam is located on a branch of Hornbecks Creek in Delaware Township, Pike County, Pennsylvania. The facility is an integral part of the surrounding development known as Wild Acres. The community is nestled in the mountains of Pike County less than five miles west of U.S. Route 209 which parallels the Delaware River in this area. Observations made during the visual inspection indicate the embankment and adjacent dike are in good condition. Heavy brush growth and small trees were observed along the embankment crest and upstream face. No evidence of seepage through the downstream embankment face, excess settlement, sloughing, erosion or animal burrows was encountered by the inspection team. Some rock slope protection has been displaced immediately adjacent the spillway right wingwall, leaving small bare areas on both the upstream and downstream embankment faces. The top of the concrete corewall exhibits excessive cracking and spalling along its entire length except for that portion associated with the dike along the right abutment which is in relatively good condition.

Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in fair condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is high. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of one-half the Probable Maximum Flood (PMF) to the full PMF. The recommended SDF for this flood control structure is the PMF. The spillway capacity is adequate for passing 71 percent of the PMF peak inflow without overtopping the dam. The spillway, therefore, is considered to be inadequate, but not seriously inadequate.

Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in fair condition. The size classification of the facility is intermediate and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility is the PMF (Probable Maximum Flood). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 40 percent of the PMF prior to embankment overtopping. A breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided in the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency.

In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Since the facility is classified near the lower bounds of the small category, the SDF is considered to be the 1/2 PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 15 percent of the PMF prior to embankment overtopping. A breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided in the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency.
