This book was released on 1981 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available data indicate that Rosner Pond Dam is in poor condition. The lack of a spillway and the poor condition of the outlet works are the primary deficiencies which cause concern for the safety of this facility. In accordance with the recommended guidelines, the spillway design flood (SDF) for this facility is in the range of 1/2 PMF to full PMF. Based on the size of the dam and degree of Downstream hazard, the selected SDF is the 1/2 PMF. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and outlet works discharge capacity will not pass the SDF (1/2 PMF) prior to overtopping the embankment. Under present conditions, the discharge/storage capacity is 11% of the PMF prior to overtopping. In accordance with the criteria outlined and evaluated in the discharge capacity for Rosner Pond Dam is considered to be seriously inadequate. The dam in its present condition is considered to be unsafe, non-emergency.

This book was released on 1981 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, field survey and calculations, Ponderosa Pines Dam is judged to be in poor condition. As the spillway cannot pass the 1/2 PMF without overtopping at less than 1/2 PMF would cause failure which would significantly increase hazard to loss of life downstream, the spillway capacity is seriously inadequate and the facility is rated unsafe, nonemergency. Although there is no visible evidence of structural instability, the erosion of the downstream slope below the outlet pipe and the leakage below the toe of the dam are of concern. Should the observed erosion and leakage remain unchecked, it could, in time, affect the structural integrity of the dam. The invert elevation of the outlet pipe is but 2.1 feet below the spillway crest. There are no means to lower the reservoir level below the present level of the pipe inlet in case of emergency. The maintenance of the dam is limited to mowing grass on the crest and a portion of the upstream slope of the embankment. The balance of the dam is poorly maintained.

This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the criteria established for these studies, Glass Pond No. 2 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 between 1/2 of the Probable Maximum Flood (PMF) and the PMF. Based on the size of the dam and reservoir, the 1/2 PMF is selected as the SDF. The existing spillway will pass only about 7 percent of the PMF before overtopping of the dam occurs. It is judged that the dam could not withstand the depth and duration of overtopping that would occur for the 1/2 PMF. Failure of Glass Pond No. 2 Dam would cause an increased hazard for loss of life downstream. Overall, the dam is considered to be in good condition. There are several deficiencies, all of which are considered to be minor. Maintenance of the dam and its appurtenant structures is generally adequate.

This book was released on 1981 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction information indicate that Bronson Pond Dam is in fair condition. The primary deficiency noted during the inspection was the lack of any spillway or outlet facilities for the dam. Based on the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between the 100-year flood and one-half the Probable Maximum Flood (PMF). Based on the size of the dam and reservoir, and the downstream conditions, the 100-year flood has been selected as the SDF. The hydrologic and hydraulic computations indicate that the combinations of reservoir storage and overflow discharge capacity pass the 100-year flood without overtopping the dam. For this reason, the overflow capacity for Bronson Pond Dam is considered to be inadequate.

This book was released on 1981 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perch Pond Dam is a composite earthfill-masonry structure, consisting of an earthfill embankment located between two dry stone masonry walls. The upstream wall is covered with concrete on the lake side of the wall. The dam is 165 feet long and 13.5 feet high. The crest is 16 feet wide, including the masonry walls. The spillway is a 12.7 foot long broad crested weir with a center pier that is 2.1 feet wide. The outlet works for the dam is an 8-in. cast iron pipe through the dam. Details of the inlet and the operational status of the outlet works could not be determined. Perch Pond Dam is judged to be in good structural condition, based on the visual inspection. Since the spillway cannot pass the 100-year flood without overtopping the dam, the spillway is rated as inadequate.

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 1978 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Belmont Lake Dam is a 27.5 foot high earth embankment across the West Branch of the Lackawaxen River. The dam has a maximum length of approximately 600 feet, and impounds a 172-acre lake. The dam was reconstructed in 1959 by adding fill over and around an existing embankment constructed about 1830. Available drawings and literature indicate that drainage blankets, grout curtains and cutoff trenches were not included in the design of this structure. The materials used for the original embankment are unknown. The upstream slope is protected with 18 inches of hand-placed riprap on a 6-inch gravel filter layer. The downstream slope is protected with vegetation.

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 1980 with total page 62 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 intermediate and the hazard classification is high. The spillway capacity combined with the available storage is sufficient to pass the PMF (Probable Maximum Flood) peak inflow without overtopping the dam. The spillway is therefore considered to be adequate. These calculations are based on a maximum stoplog elevation of 10 feet above the wetwell floor. The following recommendations are presented for immediate action by the owner: (1) That the upstream end of the outlet conduit be inspected, (2) That the downstream section of the outlet conduit be inspected on an annual basis for signs of deterioration, (3) That all brush be removed from the embankment and that the downstream wall be kept clear of all growth, (4) That a formal surveillance and downstream warning system be developed to be used during periods of high or prolonged precipitation, and (5) That a program be developed for regular inspection and maintenance.

This book was released on 1980 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general appearance of Hankins Pond Dam is fair. However, at the time of inspection, the reservoir had been drawn down to about the level of the sluiceway bottom. All stoplogs are removed in the fall for fish management Seepage and leakage, reported by the owners' representatives as occurring when the reservoir is at normal pool, could not be observed. The visual inspection check list is in Appendix A of this report. This appendix also contains sketches of survey information obtained during the inspection. The dam and its appurtenant structure appear to be in fair condition. It is recommended that brush and trees on the embankment and near the toe of the downstream wall be removed and annually controlled. If the screens in the sluiceway are not used for specific reasons, it appears that removal of the screens would improve the hydraulic conditions and reduce the hazards of blocking the outlet. The concrete wall, where it is crushed at the strut support, should be evaluated. This will determine if repair or additional support is required. Careful study should be made to definitely establish the source, clarity and volume of flow through the wall into the catch-basin when the reservoir is at normal pool elevation and if found to be excessive or otherwise hazardous, immediate steps shall be taken to correct the condition. The woodchuck hole to the right of the spillway should be filled.
