Stetson and published by . This book was released on 1980 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of documents and visual inspection of the dam and appurtenant structures did not reveal conditions which constitute an immediate hazard to human life or property. The dam, however, has a number of problem areas which require further investigation and remedial work. The structural stability analysis indicates that the dam is unstable when subjected to forces which could occur under the Probable Maximum Flood (PMF) loading condition. Unsatisfactory stability is indicated for the dam when subject to forces which could occur during the normal winter operations and the 1/2 PMF loading condition. A structural stability investigation should be started within six months to determine the characteristics of the uplift forces acting on the dam and to determine whether the foundation acts integrally with the dam section to resist overturning. Remedial work should be completed, depending on the results of the investigation, within two years. The hydrologic/hydraulic analysis establishes the spillway capacity as 10.7% of the Probable Maximum Flood (PMF). The dam will be overtopped by 10.0 feet and 4.8 feet during the PMF and 1/2 PMF respectively. The spillway is inadequate since failure of the dam during the 1/2 PMF event will not significantly increase the downstream hazard from that which would occur just prior to the dam failure.

This book was released on 1980 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. Several deficiencies were noted and these should be corrected within 6 months of the date of final approval of this report. Among the actions which should be taken are refilling the cribs which are missing material, repair of displaced timbers on the downstream face, replace broken timbers, repair of the valve on the drain, and repair of the spalling concrete on the wingwall which extends downstream of the north abutment. In addition, a detailed emergency action plan and warning system should be developed. This dam does not have sufficient spillway capacity to adequately discharge the peak outflow from one- half the PMF. The analysis indicates that the dam would be overtopped by all storms exceeding 15% of the PMF. However, the structural stability analysis indicates that the dam would be stable when subjected to the PMF storm event. Therefore, the spillway is assessed as being inadequate. The water surface level for either the PMF or one-half the PMF would result in flow around the northern end of the concrete wingwall which extends from the abutment of the dam. An accurate topographic survey should be performed where this end around flow is likely to occur.

Stetson and published by . This book was released on 1980 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of documents and visual inspection of the dam and appurtenant structures did not reveal conditions which constitute an immediate hazard to human life or property. The dam, however, has a number of problem areas which should be investigated further. The structural stability analysis indicates unsatisfactory stability for the dam when subjected to forces which could occur during winter operations (including ice loading), the Probable Maximum Flood (PMF), and 1/2 PMF events. A structural stability investigation of the dam should be started within 6 months to determine the effect of the dam's steel bar anchor system and the uplift forces acting on the base of the dam. Remedial measures should be completed within 2 years to increase the structural stability of the facility to meet the Corps of Engineers screening criteria. The hydrologic/hydraulic analysis establishes the spillway capacity as 46% of the Probable Maximum Flood (PMF) with the sluice gates open and 30% of the PMF if the gates remain closed throughout the storm. The dam will be overtopped by 2.72 feet by the PMF with the gates closed or 2.55 feet with the gates opened. However, the spillway is capable of passing the 1/2 PMF under either of these two conditions without the dam being overtopped. Therefore, the spillway is assessed as inadequate according to the Corps of Engineers screening criteria.

Stetson and published by . This book was released on 1980 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of documents and visual inspection of the dam and appurtenant structures did not reveal conditions which constitute an immediate hazard to human life or property. The dam, however, has a number of problem areas which requirefurther investigation and remedial work. The structural stability analysis indicates unsatisfactory stability would result from loadings which could occur during all investigated conditions. A structural stability investigation should be commenced within 6 months to determine the characteristics of the uplift forces acting on the dam, the properties of the existing dam and the effect of these conditions on the stability of the dam. The hydrologic/hydraulic analysis indicates that the spillway will pass only 26% of the Probable Maximum Flood (PMF). The dam will be overtopped by 6 feet and 1-1/2 feet by the PMF and 1/2 PMF respectively. Failure of the dam during the 1/2 PMF event would significantly increase the downstream hazard from that which would exist just prior to failure of the dam. Based on an initial screening, and preliminary computations, there appears to be a serious deficiency in spillway capacity so that if a severe storm were to occur, overtopping and failure of the dam would take place, significantly increasing the hazard to loss of life downstream from the dam.

Phase I Inspection Report written by George Koch and published by . This book was released on 1981 with total page 114 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. Visual inspection of this dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further engineering investigations and remedial work. Structural stability analyses performed for this report indicate that the spillway section is unstable for all conditions studied. The analysis was based on the limited information available and so may not reflect existing conditions. However, the analysis does indicate that there is a serious question concerning the stability of this dam and further investigations are required. It is recommended that within 3 months of the date of notification of the owner, investigations into the structural stability deficiencies should be commenced. These studies should include developing accurate cross sections of the dam, progressing subsurface explorations, and coring the dam. This information should then be incorporated into a detailed stability evaluation and the need for modifications to the structure should be determined. Required changes of the structure should be completed within 18 months.

Phase 1 Inspection Report written by and published by . This book was released on 1979 with total page 104 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. Hadlock Pond Dam did not reveal conditions which pose an immediate threat to life or property. Additional studies are recommended. Possible embankment overtopping can result from storms exceeding 13% of PMF. Assuming complete breaching of embankment, water surface levels could reach depths posing significant danger to residents. Consequently the spillway is assessed as unsafe non-emergency (SEE REPORT ASSESSMENT). A detailed emergency operation plan, warning system, and surveillance should be implemented as remedial measures are completed. Additional deficiencies were noted.
