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.

Mihalcin and published by . 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.

Mihalcin and published by . This book was released on 1981 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and hydrologic and hydraulic analysis, the dam is considered to be in fair condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Since the facility is classified near the lower bounds of the small category, the SDF is considered to be the 1/2 PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 15 percent of the PMF prior to embankment overtopping. A breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided in the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency.

This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history and hydrologic/ hydraulic anlaysis, the dam is considered to be in fair condition. The size classification of the facility is small and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Since the facility is classified near the lower bounds of the small category, the SDF is considered to be the 1/2 PMF. Results of the hydrologic and hydraulic analysis indicate the facility is capable of accommodating a 1/2 PMF event. Specifically, the facility will pass and/or store about 65 percent of the PMF prior to embankment overtopping. Consequently, the spillway is considered hydraulically adequate. It is noted that the spillway, as constructed, is considered to be deficient. The evaluation of its hydraulic adequacy is based upon the assumption that the channel adequately protected against erosion such that its service cannot threaten the structural integrity of the embankment.

Mihalcin and published by . This book was released on 1981 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: South Pond Dam is located on a branch of Hornbecks Creek in Delaware Township, Pike County, Pennsylvania. The facility is located about 1,000 feet south of Wild Acres Lake and less than five miles east of U.S. Route 209 which parallels the Delaware River. Observations made during the visual inspection reveal the embankment is generally well maintained and presently in fair condition. No evidence of seepage through the downstream embankment face, sloughing, animal burrows, or excess embankment settlement was noted. Some minor erosion was observed along the downstream embankment toe near the right abutment where the spillway discharge channel abuts the embankment. The erosion is due, in part, to the design of the channel, which is inadequately sized and, in part, to the lack of adequate slope protection along the channel sidewalls and downstream embankment toe. The condition of the incised area in the vicinity of the outlet conduit was observed to be somewhat saturated and covered with swamp-like vegetation. This condition may be due either to poor channel drainage or leakage along the outlet conduit. This is not considered to be significant at this time, but should continue to be observed. In addition, the steep slopes in this area apparently make routine maintenance difficult. As a result, the area around the outlet conduit has been somewhat neglected.

This book was released on 1981 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, construction history, and available engineering data, the dam is considered to be in poor condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Since the facility is classified near the lower bounds of the small category, the SDF is considered to be the 1/2 PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 29 percent of the PMF prior to embankment overtopping at the low area in the main embankment crest. Breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided in the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency. Structural deficiencies observed by the inspection team included excessive settlement of both the main embankment and dike structures, general deterioration of the spillway and outlet works, and a general lack of routine maintenance . Historical correspondences also strongly questions the construction quality of the facility.

This book was released on 1981 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and hydrologic and hydraulic analysis, the dam is considered to be in fair condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (probable Maximum Flood) and the PMF. Since the facility is classified near the upper bounds of the small category with regard to available storage capacity, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate that under existing conditions the facility will pass and/or store only about 17 percent of the PMF prior to embankment overtopping at the low area adjacent the left abutment. If the low area were regraded to the design top of dam, the spillway system would then pass about 28 percent of the PMF prior to embankment overtopping. Under existing conditions, spillway discharges are controlled by the existence of a township-owned roadway embankment and culvert that is situated about 100 feet downstream of the spillway weir.

Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in fair condition. The size classification of the facility is small and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Due to the high potential for damage to downstream structures and possible loss of life, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store approximately 50 percent of the PMF prior to embankment overtopping at the low area in the embankment crest. Consequently, the spillway is assessed as being inadequate, but not seriously inadequate. Recommended owner procedures are listed.

Book excerpt: The purpose is to determine if the dam constitutes a hazard to human life or property. Beaver Lake Lodge Dam is located on Raymondskill Creek in Milford Township, Pike County, Pennsylvania. The visual inspection of the facility suggested that the dam and its appurtenances are in poor condition. The overall appearance of the facility suggests it to be in poor condition. Remedial measures are necessary to: (1) repair to deteriorated concrete spillways, (2) remove the trees and overgrowth from the embankment crest and slopes, (3) provide adequate erosion protection along the downstream embankment toe, and (4) restore the operability of the outlet conduit, or provide an alternate means of reservoir drawdown.

This book was released on 1980 with total page 73 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 fair condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is high. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of one-half the Probable Maximum Flood (PMF) to the full PMF. The recommended SDF for this flood control structure is the PMF. The spillway capacity is adequate for passing 71 percent of the PMF peak inflow without overtopping the dam. The spillway, therefore, is considered to be inadequate, but not seriously inadequate.

Mihalcin and published by . This book was released on 1981 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pecks Pond Dam is located on Bush Kill Creek in Porter Township, Pike County, Pennsylvania. The facility is situated within 1000 feet of Pennsylvania Route 402, about 5 miles south of Interstate 84 and about 25 miles north of the city of East Stroudsburg, Pennsylvania. Observations made during the visual inspection indicate the embankment is in good condition. No evidence of seepage through the downstream embankment face, sloughing, excessive settlement, animal burrows, or signs of major maintenance neglect were observed. Minor erosion along the upstream embankment face and behind the upstream portion of the right spillway wingwall were noted, but, are not considered significant at this time. Provisions for erosion protection along the upstream embankment slope were apparently not included in the original design or in the design for the 1934 modifications. Minor cracks observed along the concrete cap that partially covers the crest were recently filled and adequately repaired. Some of the dense brush located along the downstream embankment toe had to be cut back by the inspection team in order to achieve a clear view of this area. It is suggested that control of this excess vegetation be specifically included as part of future routine maintenance.

Book excerpt: Based on a visual inspection, operational history, and hydrologic/hydraulic analysis, the dam is considered to be in good condition. The size classification of the facility is small and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Since the facility is classified near the lower bounds of the small category, the SDF is considered to be the 1/2 PMF. Results of hydrologic and hydraulic analyses indicate the facility will pass and/or store approximately 40 percent of the PMF prior to embankment overtopping at the low area in the embankment crest (elevation 1177.4). Breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided by the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency. Recommendations for owner action are listed.
