Horton Lake Dam is located on Sterling Brook in Lenox Township, Susquehanna County, Pennsylvania. The impoundment created by the dam is used for recreation and fishing. A steel plate operated by a stem and hand whell from the top of the embankment acts as a gate valve for the emergency outlet works. There are no operation or maintenance records for this gate valve. It is recommended that a formal operation and preventive maintenance schedule be developed and implemented. There is no warning system in the event of dam failure. It is recommended that an emergency warning system be developed. The current operational features are adequate for the purpose they serve. However, it is recommended that a formal maintenance and operations manual be prepared for the dam.

Loomis Lake Dam is located on an unnamed tributary to Hop Bottom Creek in Bridgewater Township, Susquehanna County, Pennsylvania, approximately 3.4 miles east of Montrose. The reservoir slopes are moderate with a good growth of ground cover. A small amount of sedimentation was present in the upper portion of the reservoir. One home and one garage are located downstream of the dam. Loss of life may occur in the event of a dam failure. In addition, the township road may suffer economic damage.

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.

Page's Lake Dam is owned and operated by the Lakeside Outing Club and is classified as a 'Significant' hazard - 'Intermediate' size dam. The dam was found to be in good overall condition on 27 October 1980. 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 1/2 Probable Maximum Flood (1/2 PMF) without overtopping the dam. A spillway design flood (SDF) in the range of the 1/2 PMF to the Probable Maximum Flood (PMF) is required for Page's Lake Dam. The 1/2 PMF was chosen as the SDF because the dam is on the low end of the 'Intermediate' size category in terms of storage. During the 1/2 PMF, the dam is overtopped by a maximum depth of 3.34 feet for a total duration of 11.83 hours. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately initiate an engineering study to further evaluate the spillway capacity and develop recommendations for remedial measures to reduce the overtopping potential of the dam.

The dam consists of a zoned, earthfill embankment that is 590 feet long and 52 feet high at its maximum section. The main spillway is a drop spillway located near the right abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. The auxiliary spillway is an excavated channel along the left abutment of the dam. It is a grass-linked excavation in earth. Based on visual inspection, available records, calculations and past operational performance, PA-467 Dam is judged to be in good condition. The existing spillway can pass the Probable Maximum Flood(PMF) without overtopping of the dam. The spillway capacity is rated as adequate. There is a slope stability analysis for the embankment, and it indicates that the embankment has adequate factors of safety. There is no evidence of significant problems threatening the embankment.

Based on a visual inspection, operational history, and available engineering data, the facility is considered to be in good 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 45 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. Calculations also indicate that if the spillway were constructed in accordance with available desing drawings, the facility could pass and/or store approximately 63 percent of the PMF.

Lake Walter Dam is located on Spring Run, approximately one mile upstream of its confluence with Meshoppen Creek in Springville Township, Susquehanna County, Pennsylvania. The condition of Lake Walter Dam is considered to be good. The only significant condition noted which requires further attention is the lack of erosion protection in the emergency spillway discharge channel. The swampy condition at the toe of the dam is not considered to be significant at this time; however, the condition should be monitored to document if seepage is developing.

DuBois Creek Dam is located on DuBois Creek, approximately 2.1 miles southwest of Hartford, Pennsylvania. The inspection was performed on 28 October 1980. A light rain was falling at the time of inspection. The dam and appurtenant structures were found to be in poor overall condition at the time of inspection. Seepage was observed at three locations passing through deteriorated portions of the concrete core wall. These seepage areas are the result of progressive deterioration of the exposed areas of the concrete core wall. The seepage has caused erosion gullies and slight irregularities on the downstream face of the dam.

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 structure is one-half the PMF. The spillway capacity is adequate for passing only 10 percent of the PMF peak inflow without overtopping the dam. The spillway is considered to be seriously inadequate. The dam is therefore unsafe, non-emergency.
