This book was released on 1980 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, and past operational performance, Lake Jamie 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 the 1/2 Probable Maximum Flood (PMF) and the PMF. Based on the criteria and the downstream conditions, the selected SDF at the dam is the PMF. Based on existing conditions, the spillways will pass about 46 percent of the PMF before overtopping of the dam occurs. However, it is judged that the dam could just withstand the depth and duration of overtopping that would occur for the 1/2 PMF. If the low areas on the top of the embankment were filled to the design elevation, the spillways would pass about 77 percent of the PMF. For either condition, the spillway capacity is rated as inadequate, but not seriously inadequate. The steep downstream slope and the seepage at the dam indicate that the embankment stability may be marginal for the normal operating condition. The main spillway weir is judged to be stable. The ability of the emergency drawdown facility to function is uncertain. The dam has significant deviations from the design data. Maintenance at the dam needs to be improved. (Author).

This book was released on 1980 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on criteria established for these studies, Lake-In-The-Clouds 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 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, with the embankment above its design elevation, the spillway will pass about 35 percent of the PMF before overtopping of the dam occurs. Failure of the dam would cause the probable overtopping and failure of a high hazard dam that is downstream. As a whole, the dam is judged to be in fair condition. No significant stability problems were observed at the embankment. The ability of the emergency drawdown facility to function is uncertain because it has not been operated recently. Maintenance at the dam is inadequate.

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.

Johnson and published by . This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemlock Lake Dam is an earth embankment about 450 feet long and 27 feet high. An ungated overflow spillway is located at the right abutment. A paved roadway has been constructed on the dam crest and a bridge has been constructed over the spillway. The dam was constructed in the early 1950's to provide a lake for recreational purposes. Hemlock Lake Dam has a maximum storage capacity of 117 acre-feet and a maximum height of 27 feet. The dam is classified as 'Small' size. Due to the potential for excessive property damage and the loss of more than a few lives in the damage center which consists of 5 houses with door sills as low as 5 feet above the stream bed located within 1,500 feet downstream of the dam, the structure classified as a 'High' hazard. Examination of the results of the hydrologic and hydraulic analyses indicates that the spillway is capable of passing approximately 26% of the Probable Maximum Flood (PMF) without the dam being overtopped. The selected Spillway Design Flood (SDF) for this 'Small' size, 'High' hazard potential structure is the PMF. The water surface elevation at the damage center is 2.4 feet higher for the breach condition than for the non-breach condition. The spillway is classified as 'Seriously Inadequate, Unsafe, Non-Emergency' since breaching of the dam significantly increases the downstream hazard potential. Based on visual observations and a review of the information obtained from the Pennsylvania Department of Environmental Resources (DER), Hemlock Lake Dam appears to be in poor condition.

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.

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.

This book was released on 1981 with total page 67 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.

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.

This book was released on 1980 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brier Crest Woods Dam is a homogeneous earthfill embankment with a toe drain. The dam, including the spillway, is 790 feet long and is 16 feet high at maximum section. The spillway is located near the middle of the dam. It is a concrete gravity weir with a concrete exit channel apron. The spillway crest is 25 feet long and is 5.0 feet below the design top elevation of the dam. The outlet works consists of a 12-inch diameter corrugated metal pipe in the spillway weir with a sluice gate at the upstream end. Based on visual inspection, available records, calculations, and past operational performance, Brier Crest Woods Dam is judged to be in good condition. The existing spillway will pass the Probable Maximum Flood (PMF), which is twice the Spillway Design Flood (SDF), with 0.2 foot of freeboard. The spillway capacity is rated as adequate. No stability problems were evident for the embankment. The spillway weir meets recommended guidelines for stability.

This book was released on 1979 with total page 66 pages. 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).'

Mihalcin and published by . This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: North Lake Dam is located on a branch of Hornbecks Creek in Delaware Township, Pike County, Pennsylvania. The facility is located approximately 1,500 feet upstream and west of wild Acres Lake, and about five miles from U.S. Route 209 which parallels the Delaware River in this area. Observations made during the visual inspection indicate the embankment is in fair condition, but in need of general maintenance. No evidence of seepage through the downstream embankment face, sloughing, erosion or animal burrows was observed. The embankment crest is noticeably low (in excess of 1-foot) near the spillway relative to the remainder of the crest. About two-thirds of the embankment is overgrown along an area extending approximately 400 feet to the right of the spillway. The vegetation is characterized as primarily brush and high weeds with clumps of small trees strewn throughout. In contrast, much of the embankment crest and upstream face are bare and unprotected with only light vegetation visible. Several long tire ruts scar the crest near the spillway. A small area characterized by swamplike vegetation is located about 350 to 375 feet from the right abutment along the downstream embankment toe. Seepage was observed at the downstream embankment toe near the outlet conduit flowing at a rate of about two to three gpm. The flow is suspected of being either seepage through the embankment foundation, or perhaps drainage from a concealed toe drain. A precise assessment of the condition is difficult without adequate design data are drawings.
