Fulton and published by . This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection of this dam and engineering analyses which have been performed revealed that several deficiencies exist on this structure. The worst of these deficiencies was the localized spalling and erosion of the gunite covering the dam. This was observed in three areas on the downstream face and toe. A more thorough examination of the gunite when there is no discharge over the spillway is needed to evaluate the extent and cause of this deterioration. If the gunite is not repaired, the interior concrete of the dam will become exposed to erosion. Using the Corps of Engineer's Guidelines for the initial review of spillway adequacy, it has been determined that the structure would be overtopped by all storms exceeding 31 percent of the Probable Maximum Flood (PMF). During a one-half PMF storm, the abutments of the dam would be overtopped by 3.4 feet. The dam is a concrete arch-gravity structure with bedrock at both abutments. While overtopping is not likely to induce failure from erosion, a stability analysis indicates that the factor of safety is below the recommended level during the one-half PMF storm. If the dam were to fail, it would increase the degree of flooding in downstream residential areas. Therefore, the spillway is assessed as seriously inadequate.

Download or read book National Dam Safety Program. Sixmile Creek Dam (Inventory Number N.Y. 395), Oswego River Basin, Tompkins County, New York. Phase I Inspection Report written by George P. Fulton and published by . This book was released on 1981 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection of the dam did not reveal any conditions which constitute an immediate hazard to human life or property. However, several deficiencies were noted which should be evaluated and remedied. The most serious deficiency was a lack of a safe, suitable access to the operating mechanism for the low-level outlet. In the event of an emergency at the dam, it would be extremely difficult to dewater the reservoir under present conditions. The hydrologic/hydraulic analysis performed indicates that the spillway does not have sufficient capacity to discharge the peak outflow from storms exceeding 7.5 percent of the Probable Maximum Flood (PMF). Since the spillway already extends across the full width of the gorge, there is no way to effectively increase its length or capacity. In addition, it should be noted that even if the dam did not exist, downstream flooding would occur during large storm events due to the configuration of the bedrock channel.

Stetson and published by . This book was released on 1979 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Examination of available documents and a visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, additional studies should be undertaken to further evaluate conditions affecting the dam. Computations prepared according to the Corps of Engineers' Screening Criteria establish the spillway capacity of 50,000 cfs at 61% of the PMF, with PMF and 1/2 PMF flows at 81,900 cfs and 46,800 cfs respectively. The spillway has been determined to be inadequate to pass the PMF. However, the spillway is not considered seriously inadequate, based on the Corps of Engineers' Screening criteria, since the dam is capable of passing the 1/2 PMF without being overtopped.

Andersen and published by . This book was released on 1981 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Based on the evaluation of the existing conditions, the condition of the Punch Bowl Dam is considered to be good. The examination of documents and the visual observations did not reveal conditions which constitute a hazard to human life or property. The spillway capacity was evaluated according to the recommended procedure and the dam was found to pass 100 percent of the Probable Maximum Flood (PMF) without significantly affecting the stability of the dam. Therefore, the spillway capacity is rated as adequate. (Author).

Stetson and published by . This book was released on 1981 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Onondaga Dam is located on Onondaga Creek in the Town of Lafayette, Onondaga County, New York, approximately 13.2 miles upstream from Onondaga Lake. The dam is used as a flood protection facility for the City of Syracuse. The visual inspection revealed that the embankment is in good condition and has been properly maintained throughout its life. No conditions were detected which might indicate instability of the structure. The surficial cracking of the exposed concrete of the spillway structure indicates that more serious spalling may soon occur. A protective coating designed to protect the structure from penetration of moisture into the concrete surfaces would serve to slow the spalling process and preserve the concrete in its present condition. This coating should be undertaken in the course of standard maintenance procedures.
Book Synopsis National Dam Safety Program. Waterloo Dam (I.D. Number NY 709), Oswego River Basin, Seneca County, New York. Phase I Inspection Report by : George Koch

This book was released on 1980 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Waterloo Dam is a concrete dam with four tainter gates and two concrete overflow sections. Lock 4 of the Cayuga-Seneca Canal is at the eastern end of the dam. There is an abandoned canal at the western end of the dam which may function as an overflow channel. The dam is a total of 241 feet long and is a maximum of 10 feet high. It is divided into 6 bays each of which has an opening of 36 feet. Examination of available documents and a visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further investigations and remedial work. The spillway does not have sufficient capacity to discharge the peak outflow from one-half the Probable Maximum Flood (PMF). For this storm event, high discharges will cause damage in the channel downstream of the dam. However, dam failure would not significantly increase the hazard to loss of life downstream from that which would exist just prior to an overtopping-induced failure.

Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection of Otisco Lake Dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further investigation and remedial action. Analysis performed indicated that the structure is only marginally stable under normal conditions and is unstable when subjected to severe loading conditions. The spillway has sufficient capacity to discharge the Probable Maximum Flood (PMF), therefore, it has been assessed as 'Adequate' according to the Corps of Engineers screening criteria. The dam has several problem areas which if left uncorrected, have the potential of hazardous conditions. These areas are: (1) Repair the deteriorated portions of the concrete on the downstream edges of the concrete paving; (2) Repair the undermining of the concrete paving; (3) Provide a program of periodic inspection and maintenance of the dam and appurtenances; and (4) An emergency action plan must be developed and maintained.
