This book was released on 1980 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in good condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is significant. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of the 100-year flood to one-half the probable maximum flood (PMF). The recommended SDF for this structure is the 100-year flood. The spillway and storage capacity is adequate for passing the SDF without overtopping the dam. Since this project can pass the SDF it is considered to be adequate.

This book was released on 1981 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection is to determine if the dam constitutes a hazard to human life or property. Crystal Lake Dam is located on the headwaters of the Lehigh River in Lehigh Township, Wayne County, Pennsylvania. The overall appearance of the dam and appurtenant structures is fair. The toe of the dam and entire embankment are covered with brush and small trees, up to one inch in diameter, obscuring the slopes from view and making of visual inspection difficult. Accordingly, some deficiencies may have gone unnoticed. The embankment slopes are irregular and do not appear to have been constructed to any particular design template. Settlement of the embankment was observed on both sides of the spillway and adjacent to the corewall along the entire length of the dam. These low areas vary in depth from only a few inches to nearly three feet. Erosion all along the upstream slope was observed at, or near, the normal pool level which has resulted in a nearly vertical two-foot drop in the slope. It is reported that riprap was placed on the slope during construction, although it was somewhat sparse in many places. There is very little riprap now remaining on the upstream slope.

This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starlight Lake Dam is located on an unnamed tributary of Shehawken Creek in Buckingham Township, Wayne County, 0.2 mile north west of Starlight, Pennsylvania. The original purpose of the impounded water was for ice harvesting and recreation. Presently, the lake is being used for recreation. The overall appearance of the dam is poor. Locations of observed deficiencies are shown on the General Plan. The profile and typical sections of the dam are presented and are based on field survey made on the days of inspection. The survey datum for this inspection is elevation 1355 feet above mean sea level for the normal water surface of the lake at the top of the spillway flashboard. On the inspection date (12/11/1980), the lake level was approximately at elevation 1355.5 or 0.5 foot above the spillway flashboard. Deficiencies observed during the field inspection are described, visible features are depicted in photographs.

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.

This book was released on 1981 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, and past performance, Kellow Lake Dam is judged to be in fair condition. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between 1/2 of the Probable Maximum Flood (PMF) and the PMF. Based on the downstream conditions, the 1/2 PMF is selected as the SDF. Under existing conditions the spillway will pass only about 22 percent of the PMF. If all stoplogs were removed from the spillway, the spillway would pass about 51 percent of the PMF. The spillway capacity is rated as adequate provided that all stoplogs are removed. Potential stability problems exist for the dam. A slope failure occurred over one reach at an unknown time in the past. Although the damage in that reach does not appear to be serious, a similar failure could occur in a more critical area and threaten the overall stability of the dam. In addition, steel beams that support the roof of the spillway outlet channel are badly corroded and create a hazardous condition. Although some maintenance has been performed, the program should be expanded to correct all deficiencies.

This book was released on 1980 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on criteria established for these studies, Lake Watawga Dam is judged to be unsafe, nonemergency, because the spillway capacity is seriously inadequate. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies from 1/2 the Probable Maximum Flood (PMF) to the PMF. Based on the criteria and the downstream conditions, the selected SDF is the PMF. Based on existing conditions, the spillway will pass about 14 percent of the PMF before overtopping of the dam occurs. It is judged that the dam would fail during the PMF. Failure of the dam would increase the hazard for loss of life downstream. As a whole, the dam is judged to be in fair condition. Deficiencies exist that are considered to be indicative of potential stability problems for the spillway. There is no functional outlet works at the dam. Maintenance at the dam is inadequate.

This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, and past operational performance, Lake Paupackan Dam is judged to be in fair condition. Considering the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between the 1/2 Probable Maximum Flood (PMF) and the PMF. The 1/2 PMF was, in this case, selected as the SDF. The spillway and reservoir, under existing conditions, will pass approximately 19 percent of the PMF before overtopping of the dam occurs. The spillway is, therefore, rated as inadequate.

This book was released on 1981 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Wildwood Lake Dam is judged to be in fair condition. Based on the size and hazard classification of the dam, the Spillway Design Flood (SDF) at the dam varies between 1/2 the Probable Maximum Flood (PMF) and the PMF. Based on the downstream conditions, the selected SDF is the PMF. Under existing conditions, the spillway will pass about 48 percent of the PMF without overtopping of the dam. It is judged that the dam could withstand the depth and duration of overtopping that would occur during the 1/2 PMF. If the low areas on the top of the dam were filled to the design elevation, the spillway would pass about 62 percent of the PMF without any overtopping. For either condition, the spillway capacity is rated as inadequate.

This book was released on 1981 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the criteria established for these studies, Whitney Lake Dam is judged to be in fair condition. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between the 100-year flood and 1/2 of the Probable Maximum Flood (PMF). The 1/2 PMF was selected as the SDF. The existing spillway will not pass the 100-year peak flood inflow. If the stoplogs on the spillway crest were removed, the spillway capacity would increase significantly, but it would still be insufficient to pass the 100-year peak flood inflow. The spillway capacity is rated as inadequate. Several deficiencies were observed at the dam. The most serious are at the spillway, which is structurally deteriorated. Although some maintenance has been performed, the existing maintenance program could be upgraded.

This book was released on 1981 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the criteria established for these studies, Elk Lake Dam is judged to be in fair condition. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam is the Probable Maximum Flood (PMF). The existing spillway will pass about 84 percent of the PMF before overtopping of the dam occurs. The spillway capacity is rated as inadequate. Several deficiencies were observed at the dam. The most serious is the probable lack of an adequate impervious barrier through the dam. Although some maintenance has been performed, the existing maintenance program could be upgraded. The following remedial measures, listed in approximate order of priority, are recommended to be undertaken by the Owner without delay: (1) Clear brush and debris on and adjacent to the dam. (2) Engage the services of a professional engineer experienced in the design and construction of dams. Utilize his advice in removing the trees on and near the embankment. If any seepage becomes evident after the brush, trees, and debris are removed, the condition should be assessed by the engineer. (3) Fill the slots by the spillway bridge with concrete or other suitable impervious material. (4) Fill the burrowing animal hole adjacent to the spillway with suitable impervious material.

This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greene-Dreher Dam is a 20-foot high earthern embankment, 1,000 feet long which impounds a 152 acre-foot flood water retention pool. Total estimated volume of fill is approximately 30,000 cubic yards. The zoned embankment was constructed on natural soils without a cutoff trench or a grout curtain. The embankment contains three material zones; Zone 1, a relatively impervious core of silt and and silty sand; Zone 2, composed of silty gravel and silty sand; and an outer shell of Zone 3 material, described as rock larger than 6 inches in diameter. The embankment crest is 12 feet wide at a design settled elevation of 2,036 feet, and both upstream and downstream slopes are 3H:1V. The downstream section of the embankment contains a filter blanket approximately 2 feet thick, 30 feet wide and 320 feet long. The filter blanket is drained by a 6-inch diameter perforated corrugated metal pipe connected to a 6-inch diameter pipe which outlets adjacent to the principal spillway outlet.
