This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solebury Farm Dam is located on Honey Hollow Creek in Solebury Township, Bucks County, Pennsylvania. At the time of the inspection, the water surface was approximately one inch above the spillway crest. The overall appearance of the dam is fair, although the thick overgrowth on the dam made a complete visual assessment difficult. The alignment of the upstream embankment face appears to be good. Although no slope protection exists, no distressed areas were noted. The vertical alignment of the top of the dam varies approximately one foot over the 150 foot length of the dam with the design top of the dam being the low point. The downstream embankment face appears to be uniform. No areas of slope failure were noted. Seepage estimated at 2 gpm was evident about 10 feet from the toe of the dam and 20 feet from the spillway outlet channel. The seepage appeared to be clear at the time of the inspection. The entire embankment is overgrown with trees and brush. Trunk diameters range up to 12 inches with heights approaching 30 feet. The spillway is excavated into bedrock which appears to be resistant to weathering. No areas of scour or rock deterioration were observed.

Johnson and published by . This book was released on 1981 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silver Lake Dam is an earth embankment about 350 feet long and 15 feet high at its maximum section. An ungated overflow masonry spillway is located at the approximate midpoint of the embankment. Silver Lake Dam has a maximum storage capacity of 51 acre feet and a maximum height of 15 feet. The dam is therefore classified as 'Small' size structure. Because of the potential for the possible loss of a few lives and appreciable property losses in the damage area, located about 0.6 miles downstream, the dam is considered to be a 'Significant' hazard structure. The selected Spillway Design Flood (SDF) for Silver Lake Dam ('Small' size, 'Significant' hazard) is the one hundred year storm. An examination of the hydrologic and hydraulic analyses indicates that the spillway is not capable of passing the SDF without the dam being overtopped. The spillway is classified as 'Inadequate'. Based on visual observations and a review of the information obtained from the Pennsylvania Department of Environmental Resources, Silver Lake Dam appears to be in fair condition.

Johnson and published by . This book was released on 1981 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Camp Delmont Dam is a concrete capped rockfilled timber crib structure with steel and timber sheetpile abutments about 190 feet long, with a maximum height of 19 feet. The dam has a maximum storage capacity of 236 acre feet and a maximum height of 19 feet which places it in the 'Small' size category. Because of the chance for appreciable damage to several cottages located downstream of the site and little chance for loss of life due to failure of the dam, the dam is judged to be a 'Significant' hazard structure. Due to the inhabitable dwellings located downstream of the dam, fifty percent of the Probable Maximum Flood (PMF) was selected as the appropriate Spillway Design Flood (SDF). An examination of the results of the hydrologic and hydraulic analyses indicates that the spillway and adjacent roadway are capable of passing 36% of the PMF without overtopping the dam abutments. The selected SDF for the dam is fifty percent of the PMF. Since the spillway is not capable of passing the SDF, the spillway is classified as 'Inadequate'. Further examination of the hydrologic and hydraulic analyses indicates that the spillway and adjacent roadway are capable of passing the 100 year event without overtopping the dam abutments. Based on visual observations and a review of the information obtained from Pennsylvania Department of Environmental Resources, Camp Delmont Dam appears to be in good condition.

Johnson and published by . This book was released on 1981 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hosensack No. 4 Dam is a masonry structure with an upstream embankment. The dam has a maximum height of about 32 feet and a length of 310 feet. A 175-foot long overflow spillway is located about 100 feet from the right abutment near the center of the structure and is capped with concrete in the masonry portion. A 24-inch diameter reinforced concrete drain pipe is located in the non-overflow portion of the dam about 3.5 feet left of the spillway section. Discharge through the pipe is controlled with stop planks in a drainage tower approximately 15 feet downstream from the intake. A review of the results of the hydrologic and hydraulic analyses indicates that the spillway is able to pass the Spillway Design Flood (SDF) without the dam being overtopped; therefore, the spillway is considered 'Adequate'. Based on visual observation and a review of the information obtained from the Pennsylvania Department of Environmental Resources, Hosensack No. 4 Dam appears to be in poor condition.

This book was released on 1979 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bear Creek Lake Dam is a rock filled timber crib structure approximately 325 feet long and 17 feet high at its maximum section. An ungated drop spillway with an 158-foot long sharp crested weir is located approximately 60 feet from the right abutment (looking downstream). The 80 acre lake is used for recreation by the residents of Bear Creek Village. It is unknown when the dam was constructed. In the state inspection report of April, 1915 it is stated, 'This dam was constructed a great many years ago, but it has been repaired from time to time, so that more than likely none of the original structure is now in existence.' Examination of the results of the hydrologic and hydraulic analysis indicate that the drop spillway is capable of passing 11 percent of the Probable Maximum Flood (PMF) without overtopping of the embankment. Failure of the dam would significantly increase the hazard to loss of life downstream of the dam. Therefore, the capacity of the drop spillway is classified as 'seriously inadequate.' The dam is considered to be 'unsafe (non-emergency).'

This book was released on 1980 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to criteria established for these studies, Lake Henry Dam is classified as unsafe, nonemergency, because of the seriously inadequate spillway capacity, the significant seepage, and the whirlpools that have reportedly developed previously in the lake. The recommended Spillway design Flood (SDF) for the size and hazard category of the dam is the Probable Maximum Flood (PMF). The existing spillways can pass about 19 percent of the PMF before overtopping of the dam occurs. It is judged that the dam would fail during the 1.2 PMF. Failure of the dam would increase the hazard to loss of life downstream. As a whole, the dam is judged to be in poor condition.

This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction information indicate that Lake Quinn Dam is in fair condition. Deficiencies noted during the inspection included the lack of functional drawdown facilities and minor seepage through the masonry near the right abutment. Based on the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between 1/2 the Probable Maximum Flood (PMF) and the PMF. The 1/2 PMF has been selected as the SDF due to the size of the dam and reservoir, and the downstream conditions. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass only 3 percent of the PMF without overtopping the dam. Overtopping the dam could cause failure, which would lead to a significant increase in downstream loss of life and property damage. Therefore, the spillway for Lake Quinn Dam is considered to be seriously inadequate, and the dam is judged to be unsafe, non-emergency.

Book excerpt: Lake Akiba Dam is a 360-foot long, 22-foot high earth embankment dam, constructed in 1926 to provide a lake for recreational use. The maximum storage capacity of Lake Akiba is 280 acre-feet. The dam has a crest width of approximately seven feet and side slopes both upstream and downstream which average 2H:1V. Based upon the visual inspection of the dam review of the information provided by the Pennsylvania Department of Environmental Resources (Der), the Lake Akiba Dam is considered to be in fair condition. The spillway, however, is in poor condition an should be investigated immediately.

This book was released on 1981 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Mihalcin and published by . This book was released on 1981 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 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.

This book was released on 1980 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lower Hemlock Dam is a 420 foot long earthfill structure with a maximum embankment height of 15 feet. Plate IV, Appendix E, indicates a concrete core wall along the centerline of dam. The top of the dam is used as a public roadway and has a bituminous surface. The spillway is located near the left abutment of the embankment. A fish guard-screen is attached to the upstream side of the concrete ogee section. The roadway crosses the spillway discharge channel immediately downstream from the weir (Photograph 7, Appendix C). The bridge is a concrete slab deck structure supported on two piers and two abutment walls. The outlet control structure is constructed differently from that shown on Plate IV, Appendix E. It actually consists of a valve chamber with the valve located on the inside of the upstream wall. Water is discharged directly into the valve chamber and flows from there through a 24inch diameter outlet pipe under the embankment to the downstream toe. The valve chamber is covered with a large overhanging concrete slab and is accessible by a footbridge from the crest of the dam. (Author).

This book was released on 1980 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maple Lake Dam is a homogeneous, earthfill embankment. It is 35 feet high at its maximum section and 685 feet long. The main spillway is located at the maximum section of the dam. It consists of a reinforced concrete riser structure near the upstream toe of the dam, a 24-inch diameter conduit, and a concrete outlet structure at the downstream toe of the dam. The auxiliary spillway is an excavated, trapezoidal channel at the left abutment of the dam. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Maple Lake Dam is judged to be in good condition. Based on existing conditions, the main and auxiliary spillways will pass an approximate minimum of 48 percent of the Probable Maximum Flood (PMF before overtopping of the dam occurs. No stability problems were evident for the embankment at the time of the visual inspection, but a potential hazard to stability exists due to erosion that might occur when there is flow in the auxiliary spillway.
