Available in PDF, EPUB and Kindle. Book excerpt: Bear Creek Lake Dam is a rock filled timber crib structure approximately 325 feet long and 17 feet high at its maximum section. An ungated drop spillway with an 158-foot long sharp crested weir is located approximately 60 feet from the right abutment (looking downstream). The 80 acre lake is used for recreation by the residents of Bear Creek Village. It is unknown when the dam was constructed. In the state inspection report of April, 1915 it is stated, 'This dam was constructed a great many years ago, but it has been repaired from time to time, so that more than likely none of the original structure is now in existence.' Examination of the results of the hydrologic and hydraulic analysis indicate that the drop spillway is capable of passing 11 percent of the Probable Maximum Flood (PMF) without overtopping of the embankment. Failure of the dam would significantly increase the hazard to loss of life downstream of the dam. Therefore, the capacity of the drop spillway is classified as 'seriously inadequate.' The dam is considered to be 'unsafe (non-emergency).'

Phase I Inspection Report written by Albert Charles Hooke and published by . This book was released on 1979 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dam G is a homogeneous earthfill embankment with a concrete core-wall. The embankment is 490 feet long and 19 feet high at maximum section. There are two outlet works at the dam. The first outlet works, which is near the right end of the embankment, consists of a concrete intake structure, two 24-inch diameter cast-iron pipes, and a valve house. This outlet works is connected to the water supply system. The second outlet works, which is near the left end of the dam, is similar to the first except it consists of a single 24-inch diameter pipe. The second outlet works provides the emergency drawdown capability. The concrete chute spillway is at the left abutment of the dam. Its crest is 3.0 feet below the design elevation of the top of the dam and is 75 feet long. The approach channel is short and concrete paved. The exit channel is a continuation of the chute. A bridge extends across the spillway crest. It is supported by two piers.

Phase 1 Inspection Report written by and published by . This book was released on 1981 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this inspection is to determine if the dam constitutes a hazard to human life and property. The Dam's location is Bucks Township, Luzerne County. The overall appearance and general condition of the dam and appurtenances are fair. The spillway crest has been raised and the dam crest is two feet below design elevation. These and other noteworthy deficiencies noted. The reservoir pool was 3.5 feet below spillway crest (corewall) on the day of the initial inspection, 22 October 1980. The lake was purposely drawn down so that maintenance of the dam could be performed. On the date of the review inspection, the reservoir level was one foot above the spillway crest (corewall).

Phase I Inspection Report written by Frederick Futchko and published by . This book was released on 1979 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sunrise Lake Dam is a homogeneous earthfill embankment 478 feet long and 27 feet high at its maximum section. The embankment has a curved alignment. A concrete chute spillway is located near the right abutment of the top of the. The approach channel is the reservoir area. The ogee crest is 105 feet long and 7.25 feet lower than the design elevation of the dam. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Sunrise Lake Dam is judged to be in good condition. The spillway capacity is rated as adequate. The spillway can pass the Probable Maximum Flood (PMF) without overtopping of the dam. The headwall at the conduit outlet is tilted and is considered to be unsatisfactory. In the absence of stability computations showing that an adequate factor of safety exists, the downstream slope is considered to have a marginal factor of safety because of the steepness of the slope.

Phase I Inspection Report written by O'BRIEN AND GERE ENGINEERS INC PHILADELPHIA PA JUSTIN AND COURTNEY DIV. and published by . This book was released on 1979 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Penn Lake Dam is an earth embankment approximately 350 feet long and 44 feet high at its maximum section. The spillway consists of twelve 42-inch diameter, 20-foot long pipes located approximately 1,000 feet left (looking downstream) of the dam. Earth swales on both sides of the battery of pipes function as auxiliary spillways. The 56 acre reservoir is used for recreation by members of the Penn Lake Association. Examination of the results of the hydrologic and hydraulic analyses indicates that the spillway (pipes and swales) is capable of passing 48 per cent of the Probable Maximum Flood (PMF) without overtopping of the embankment. Failure of the dam would increase the hazard of loss of life downstream of the dam. The capacity of the spillway system is therefore classified as 'Seriously Inadequate.' The dam is considered to be unsafe (non-emergency). Based on visual observations made during the date of the inspection, the dam is considered to be in poor condition.

Lake Aleeda Dam (NDI-ID Number PA-00557) (DER-ID Number 40-219) (SCS-ID Number PA-530), Delaware River Basin Tributary to Bear Creek, Luzerne County, Pennsylvania. Phase I Inspection Report written by GANNETT FLEMING CORDDRY AND CARPENTER INC HARRISBURG PA. and published by . This book was released on 1979 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: In reviewing this report, it should be realized that the reported condition of the dam is based on observations of field conditions at the time of inspection along with data available to the inspection team. In cases where the reservoir was lowered or drained prior to inspection, such action, while improving the stability and safety of the dam, removes the normal load on the structure and may obscure certain conditions which might otherwise be detectable if inspected under the normal operating environment of the structure. 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 Albert Charles Hooke and published by . This book was released on 1979 with total page 99 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, Dam F is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The spillway can pass 29 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The Owner has placed sandbags along the spillway crest, which reduces the spillway capacity further. The resulting outflows from the failure of Dam F would overtop and cause the failure of Dam G. This would result in the loss of life. As a whole, the dam is judged to be in fair condition. There are bulges on the downstream slope that apparently have not stabilized. The dam has essentially no operational emergency drawdown capability. Maintenance at the dam is marginal.

Download or read book National Dam Inspection Program. Silver Lake Dam (NDI ID PA 00791, PA DER 9-78), Delaware River Basin, Van Horn Creek, Pennsylvania. Phase I Inspection Report written by Peter C. Johnson and published by . This book was released on 1981 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silver Lake Dam is an earth embankment about 350 feet long and 15 feet high at its maximum section. An ungated overflow masonry spillway is located at the approximate midpoint of the embankment. Silver Lake Dam has a maximum storage capacity of 51 acre feet and a maximum height of 15 feet. The dam is therefore classified as 'Small' size structure. Because of the potential for the possible loss of a few lives and appreciable property losses in the damage area, located about 0.6 miles downstream, the dam is considered to be a 'Significant' hazard structure. The selected Spillway Design Flood (SDF) for Silver Lake Dam ('Small' size, 'Significant' hazard) is the one hundred year storm. An examination of the hydrologic and hydraulic analyses indicates that the spillway is not capable of passing the SDF without the dam being overtopped. The spillway is classified as 'Inadequate'. Based on visual observations and a review of the information obtained from the Pennsylvania Department of Environmental Resources, Silver Lake Dam appears to be in fair condition.

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 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.

Phase I Inspection Report written by Frederick Futchko and published by . This book was released on 1980 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on criteria established for these studies, Mountain Lake 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 category of the dam varies between 1/2 of the Probable Maximum Flood (PMF) and 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 20 percent of the PMF before overtopping of the dam occurs. Failure of the dam would increase the hazard to loss of life downstream. If the dam were raised to its design elevation, the spillway would pass about 28 percent of the PMF. The spillway capacity would still be rated as seriously inadequate. As a whole, the dam is judged to be in poor condition. Lack of maintenance has caused the spillway to deteriorate to such an extent that it is on the verge of collapse. It is unlikely that the spillway could withstand any flood of significant duration. (Author).

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.

This book was released on 1981 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild Acres Lake Dam is located on a branch of Hornbecks Creek in Delaware Township, Pike County, Pennsylvania. The facility is an integral part of the surrounding development known as Wild Acres. The community is nestled in the mountains of Pike County less than five miles west of U.S. Route 209 which parallels the Delaware River in this area. Observations made during the visual inspection indicate the embankment and adjacent dike are in good condition. Heavy brush growth and small trees were observed along the embankment crest and upstream face. No evidence of seepage through the downstream embankment face, excess settlement, sloughing, erosion or animal burrows was encountered by the inspection team. Some rock slope protection has been displaced immediately adjacent the spillway right wingwall, leaving small bare areas on both the upstream and downstream embankment faces. The top of the concrete corewall exhibits excessive cracking and spalling along its entire length except for that portion associated with the dike along the right abutment which is in relatively good condition.
