Phase I Inspection Report written by and published by . 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.

Phase I Inspection Report written by Frederick Futchko and published by . 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.

Phase I Inspection Report written by Gideon Yachin and published by . 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.

Phase I Inspection Report written by Frederick Futchko and published by . 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.

Phase I Inspection Report written by Gideon Yachin and published by . This book was released on 1981 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lower Twin Lake Dam is located on a branch of Kinneyville Creek in Preston Township, Wayne County, Pennsylvania. The overall appearance of the dam is poor. Location of observed deficiencies are shown on the General Plan presented. The profile and typical sections of the dam are presented and are based on field survey made on the day of inspection. The survey datum for this inspection is elevation 1495 feet above mean sea level for the normal water surface of the lake. On the inspection date (12/02/80), the lake level was approximately at elevation 1495, which is 1.5 feet below the low point on the dam crest. Deficiencies observed during the field inspection are described below, and are further illustrated. Visible features are depicted in photographs presented.

Phase I Inspection Report written by and published by . 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.

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . This book was released on 1981 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Big Elk Lake Dam is considered to be good. The flood discharge capacity of the dam was evaluated according to the recommended criteria and it was found that the dam cannot pass the recommended spillway design flood (100-year flood) without overtopping the dam. THerefore, flood discharge capacity of the dam is classified to be inadequate. The following recommendations should be implemented as soon as possible or on a continuing basis. (1) The owner should determine the nature and extent of improvements required to provide adequate spillway capacity. (2) The owner should investigate the need to install low level outlet facilities or prepare plans to lower the lake in the event of an emergency. (3) Around-the-clock surveillance should be provided during unusually heavy runoff and a formal warning system developed to alert the downstream residents in the event of emergencies. (4) The owner should develop a formal operating and maintenance plan and inspect the dam regularly and perform necessary maintenance. (Author).

Phase I Inspection Report written by GANNETT FLEMING CORDDRY AND CARPENTER INC HARRISBURG PA. and published by . 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.

Download or read book National Dam Inspection Program. Beaver Lake Dam (NDI-ID Number PA-00160, DER-ID Number 64-180), Delaware River Basin, Wayne County Pennsylvania. Phase I Inspection Report written by Hendrik Jongsma and published by . 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.

Phase I Inspection Report written by GANNETT FLEMING CORDDRY AND CARPENTER INC HARRISBURG PA. and published by . 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.

Phase I Inspection Report written by CORPS OF ENGINEERS BALTIMORE MD BALTIMORE DISTRICT. and published by . 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.

Phase I Inspection Report written by Frederick Futchko and published by . This book was released on 1981 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of a Phase I Investigation is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general condition of the dam is based upon available data and visual inspections. Detailed investigations, and analyses involving topographic mapping, subsurface investigations, testing, and detailed computational evaluations are beyond the scope of a Phase I Investigation; however, the investigation is intended to identify any need for such studies. Phase I inspections are not intended to provide detailed hydrologic and hydraulic analyses. In accordance with the established Guidelines, the spillway design flood is based on the estimated 'Probable Maximum Flood' for the region (greatest reasonably possible storm runoff), or fractions thereof. The spillway design flood provides a measure of relative spillway capacity and serves as an aid in determining the need for more detailed hydrologic and hydraulic studies, considering the size of the dam, its general condition and the downstream damage potential.

Phase I Inspection Report written by and published by . This book was released on 1981 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hunter Lake Dam is an earth embankment with a sheet timber core about 300 feet long and 13 feet high. The embankment has a top width of 42 feet and downstream and upstream slopes of 2H:1V an 1H:1V, respectively. The dam was constructed in 1928-29 to provide a lake for recreational purposes. Based on the visual observations, discussions with the Owner's representative, and information obtained from the Pennsylvania Department of Environmental Resources, Division of Dam Safety, Hunter Lake Dam is considered to be in fair condition.

Download or read book National Dam Inspection Program. Lake Como Dam (NDI ID Number PA-00130, DER ID Number 64-16), Delaware River Basin, Kinneyville Creek, Wayne County, Pennsylvania. Phase I Inspection Report written by and published by . This book was released on 1981 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Como Dam is a composite structure consisting of an upstream earth embankment and a downstream near-vertical stone wall. The dam is 12.2 feet high and 196 feet long, including spillway. The spillway is located near the middle of the dam, consisting of a 28.3-foot long sharp crested concrete weir, terminating with vertical concrete endwalls. There are no facilities to drain the reservoir. Based on visual inspection, field survey, available records, calculations and past operational performance, Lake Como Dam is judged to be in fair condition. Because the spillway capacity of 535 cfs is less than the estimated 1240 cfs peak discharge of the 100-year flood, the spillway capacity is rated as inadequate. Considering the rotted condition of the plank sheeting to the right of the spillway wall, further deterioration of the sheeting may cause leakage and the stability of the dam could, in time, be affected.
