Phase I Inspection Report written by and published by . This book was released on 1981 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of existing conditions, the condition of Rossiter Dam is considered to be unsafe/nonemergency due to a seriously inadequate spillway capacity. The overall condition of the dam is considered to be poor. The spillway structures have partially collapsed and the dam is overgrown with large trees and thick brush, precluding a complete inspection. The spillway capacity was evaluated according to the recommended criteria and was found to be seriously inadequate. According to the recommended criteria, small dams in the high hazard category are required to pass from one-half to full Probable Maximum Flood (PMF). In view of the small size of the dam, one- half of the PMF was selected as the spillway design flood. Flood discharge capacity was evaluated according to the recommended procedure and was found to pass 20 percent of the PMF without overtopping the embankment. Since the spillway capacity is less than 50 percent of the PMF and results of a breach analysis indicate that the potential loss of life and downstream damage would be significantly increased due to a dam failure, the spillway is classified to be seriously inadequate.

Phase I Inspection Report written by Lawrence D. Anderson and published by . This book was released on 1979 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the conditions of Musser Forests Dam, the dam is considered to be unsafe due to severe erosion in the primary spillway and emergency discharge channel along the toe of the dam near the left abutment and due to the lack of an operable outlet works for the reservoir. However, it is not considered to be an emergency condition. Field observations indicate that the crest of the dam is irregular with elevations ranging from 1.7 to 5.9 feet above the emergency spillway crest level. The irregularities do not appear to be due to recent movements. The upstream slope of the dam has no erosion protection and has been partially eroded by wave action. The emergency spillway approach channel is overgrown with tall grass and cattails which may constitute a partial obstruction to flow through the spillway. The flood discharge capacity of Musser Forests Dam was evaluated and found to pass 30% of the probable maximum flood (PMF) without overtopping the low spot on the crest of the dam. Therefore, according to the recommended criteria, the flood discharge capacity of Musser Forests Dam is classified to be inadequate.

Phase I Inspection Report written by Bernard M. Mihalcin and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in good 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. Due to the relatively small storage capacity and the unusually stable embankment configuration the SDF for the facility is considered to be the 1/2-PMF. Results of the hydrologic and hydraulic analysis indicate the facility is capable of passing and/or storing a flood of 1/2-PMF magnitude. Consequently, the spillway is considered adequate. It is recommended that the owner: (a) Develop a formal emergency warning system to notify downstream residents should hazardous conditions develop. Included in the plan should be provisions for around-the-clock surveillance of the facility during periods of unusually heavy precipitation. (b) Observe the cracking in the spillway overflow wall and outlet conduit headwall in future inspections and take remedial measures if necessary. (c) Develop formal manuals of operation and maintenance to ensure the continued proper care of the facility.

Phase I Inspection Report written by Bernard M. Mihalcin and published by . This book was released on 1979 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cherry Run Dam is a zoned earth embankment with a central concrete corewall. The embankment measures approximately 430 feet long (including spillway) and 22 feet high. The facility is provided with an ogee-shaped concrete spillway located about 100 feet from the right abutment. The spillway crest is 132 feet long. Based on a visual inspection, maintenance of Cherry Run Dam appears minimal to non-existent and the facility is considered to be in poor condition. Deficiencies noted by the inspection team included heavy overgrowth of the embankment sections (particularly to the right of the spillway), delamination of the spillway surface, cracking and misalignment of the spillway wingwalls, heavy overgrowth within the discharge channel, an inoperable outlet works, and no emergency warning systems in effect. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only 40 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.

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . This book was released on 1979 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PA-479 dam is one of the 14 flood control projects in the Harmon Creek watershed. The dam consists of an earth embankment approximately 650 feet long with a maximum height of 63 feet from the downstream toe and a crest width of 14 feet. The flood discharge facilities for the dam consist of a drop inlet primary spillway located near the left abutment (looking downstream) and an emergency spillway, also located on the left abutment. Based on the evaluation of the conditions as they existed on the dates of inspection and as revealed by visual observations, the condition of PA-479 dam is assessed to be good. The spillway capacity is classified as adequate according to the recommended criteria.

Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1980 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Doverspike No. 1 Dam is considered to be poor due to the inadequate size of the emergency spillway discharge channel. Field observations indicate that the capacity of the discharge channel is significantly less than the capacity of the emergency spillway overflow section, and a major portion of the flow passing the control section would spill onto the embankment, posing a potential for erosion of the embankment. The condition of the embankment is considered to be good. According to the recommended criteria, intermediate size dams in the high hazard category are required to pass full probable maximum flood (PMF) without overtopping the embankment. The flood discharge capacity was evaluated according to the recommended criteria and was found to pass about 30 percent of the PMF without overtopping the embankment. Therefore, the spillway capacity is rated to be inadequate. Because overtopping of the embankment during the passage of 50 percent of the PMF for a duration of 3.2 hours with a maximum depth of 0.4 foot is not considered to present a serious breach potential, the spillway is not considered to be seriously inadequate.

Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1980 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Elroy Face Dam is considered to be unsafe/nonemergency. A portion of the embankment crest adjacent to the overflow spillway located on the left abutment was found to be about 3 feet below the design crest level and only 8 inches above normal pool level. Relative to this low spot, the capacity of the spillway is estimated to be 66 cfs (approximately 5 percent of the probable maximum flood), which is significantly less than the lower limit of the recommended spillway design flood of the 100-year flood for the dam, based on its size and hazard classification. Therefore, the spillway capacity is considered to be inadequate. A preliminary survey of the crest of the dam indicated that the remaining portion of the crest is also below the design level by about one to two feet. The crest and the downstream face of the dam were found to be covered with thick brush and trees, essentially precluding proper inspection of the embankment. The embankment was generally found to be in poor condition with extensive swampy areas along the downstream toe and shoreline erosion on the upstream side. The spillway structures and the downstream end of the outlet pipe were found to be structurally in poor condition and requiring repairs.

Phase I Inspection Report written by and published by . This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Pioneer Lake Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. The dam and appurtenant structures appear to be in fair condition. No major erosion was observed on the embankment crest. An erosion area was observed at the outlet for the 12 in. diameter cast iron pipe. Erosion at the outlet of the 12 in. diameter pipe exists on the downstream slope of the dam near the toe. Seepage 100 ft. right of the spillway channel was measured to be approximately 50 gallons per minute. A 30 in. corrugated metal pipe exists beneath the roadway near the outlet for the emergency spillway. It was observed during the inspection that the pipe is collapsing near the center of the pipe. Trees were observed growing along the upstream edge of the crest, and dense vegetation was observed along the entire length of the downstream slope. The Pioneer Lake Dam is a high hazard-small size dam. The recommended spillway design flood (SDF) for a dam of this size and classification is in the range of the 1/2 PMF to PMF. Due to the downstream potential for loss of life and property damage, the spillway design flood has been selected as the PMF. The spillway and reservoir are capable of controlling approximately 11% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. Pioneer Lake Dam is classified as unsafe, non-emergency.

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . This book was released on 1979 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PA-482 dam is one of the 14 flood control projects in the Harmon Creek watershed. The dam consists of an earth embankment approximately 460 feet long with a maximum height of 38 feet from the downstream toe and a crest width of 14 feet. The flood discharge facilities for the dam consist of a drop inlet primary spillway located at the center of the embankment and an emergency spillway on the left abutment (looking downstream). The primary spillway structures consist of a two-stage reinforced concrete riser, a 24-inch-diameter reinforced concrete conduit, and a reinforced concrete impact basin at the downstream end of the outlet pipe. The emergency spillway is a 200-foot-wide trapezoidal earth channel excavated into the left abutment. The reservoir outlet for the dam consists of a 15-inch steel pipe extending from the upstream toe of the dam to the drop inlet structure. Flow through the reservoir outlet is controlled by a manually operated sluice gate lcoated in the drop inlet structure.

Phase I Inspection Report written by GAI CONSULTANTS INC MONROEVILLE PA. and published by . This book was released on 1979 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beaver Dam is an earth embankment approximately 32 feet high and 385 feet long (including spillway). The dam is constructed with a masonry spillway located about 35 feet left of the right abutment. The crest of the spillway is 100 feet long and about 11 feet below the top of its wingwalls. Based on a visual inspection, operational history, and available engineering data, the dam is consisered to be in poor condition. The defunct facility has been essentially abandoned since 1952 and its reservoir is sediment filled. Results of the hydrologic and hydraulic analysis indicate that the facility is capable of passing and/or storing only 36 percent of the PMF without embankment overtopping. Structural deficiencies noted by the inspection team included substantial embankment overgrowth, an access road cut through the embankment near the left abutment, cracking of the masonry spillway wingwalls, and a sediment filled reservoir. Due to the seriously inadequate spillway and overall poor condition, the facility is considered unsafe but non-emergency as failure is not considered imminent.

Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in good 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. Due to the high potential for damage to downstream structures and loss of life, the SDF for the facility is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store a flood of PMF magnitude. Consequently, the spillway is considered adequate.

This book was released on 1980 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sample Run Dam consists of an earth embankment approximately 325 feet long with a maximum height of approximately 23 feet from the downstream toe. The crest width is approximately 10 feet. As designed, the downstream face of the dam was to be protected by grass, and a vertical concrete wall on the upstream side was to provide shoreline protection. Presently, the downstream face of the dam is covered with brush and trees up to 10 feet high and the concrete wall on the upstream side has partially collapsed. The spillway structures are comprised of an 18-foot-wide concrete ogee overflow section which discharges into an 18-foot-long concrete channel, incorporating an energy dissipator sill. Based on the evaluation of the existing conditions, the condition of Sample Run Dam is considered to be poor. The dam is abandoned and is in complete disrepair. A valve house located at the downstream toe of the dam has collapsed, covering most of the operating equipment with rubble. The flood discharge capacity of the dam was evaluated according to the recommended procedure and was found to pass 20 percent of the probable maximum flood (PMF).

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . This book was released on 1980 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edwards Dam consists of an earth embankment approximately 300 feet long with a maximum height of 30 feet from the downstream toe. The crest of the dam is irregular in the transverse direction with an average crest width of 8 feet. While the middle of the embankment is straight across the valley, short sections on each abutment side curve upstream. As designed, the embankment slopes are 2H to 1V on the upstream slope and 1.5H to 1V on the downstream slope. The flood discharge facilities for the reservoir consist of a 15-foot-wide, 4-foot-deep open channel located on the left abutment, equipped with an ogee overflow section. Flow from the overflow section discharges onto a 10-foot-long concrete apron which in turn discharges into an earth channel. The records indicate that the outlet facilities consist of a 12-inch cast-iron blow-off pipe and a 6-inch cast-iron supply line. Flow through the blow-off valve is controlled by a downstream valve located near the downstream toe of the embankment. The reservoir appears to be significantly silted. Therefore, the operational condition of the blow-off valve is questionable. This outlet system constitutes the emergency drawdown facility for the reservoir. (Author).

Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1980 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The condition of Doverspike No. 2 Dam is considered to be good, except that the dam has no outlet works and no formally engineered spillway facilities. A low spot on the crest of the dam located at the junction of the embankment and the right abutment appears to be the intended spillway overflow section. On the dates of inspection, the pool level was found to be approximately 5 feet below the low spot on the crest of the dam, and as reported by the representative of the owner, the pool is normally maintained at that level by seepage and evaporation losses from the reservoir. According to the recommended criteria, intermediate size dams in the significant hazard category are required to pass from 50 percent of the probable maximum flood (PMF) to full PMF. In view of the downstream damage potential, the lower limit of the recommended range is considered to be applicable to this dam. The flood discharge capacity was evaluated according to the recommended procedure and the dam was found to impound less than 20 percent of the PMF without overtopping the embankment. Therefore, the flood discharge capacity of the dam is classified to be inadequate.
