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 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, Brookville Water Works Dam was found to be in good condition and adequately maintained. The flood discharge capacity of the dam was evaluated according to the recommended procedure and was found to pass less than the 100-year flood without overtopping the embankment portion of the dam. The recommended spillway capacity range is between the 100-year flood and 50 percent of the probable maximum flood (PMF). Considering the low downstream damage potential, the lower limit of the recommended spillway capacity range was considered to be applicable to this dam. Therefore, the flood discharge capacity is classified to be inadequate. However, considering that the slopes of the earth embankment are protected with riprap and the dam has a concrete core wall, and further that the dam has withstood overtoppings in the past without breaching, overtopping of the earth embankment during the passage of 100-year flood can be permitted. Therefore, enlargement of the spillway is not considered to be justified. (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.

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 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The J.C. Bacon Dam consists of an earth embankment approximately 1000 feet long with a maximum height of 95 feet from the downstream toe and a crest width of 15 feet. The flood discharge facilities for the dam consist of a combined primary and emergency spillway located on the left abutment (looking downstream). The spillway structures consist of a trapezoidal earth approach channel, a 115-foot-long concrete overflow section, and a partially concrete-lined spillway discharge channel. The concrete lining in the spillway discharge channel extends approximately 230 feet downstream from the control section to a level approximately 37 feet above the normal pool level of the dam. The outlet works consist of a 5-foot by 5-foot reinforced concrete outlet conduit, a 24-inch cast-iron water supply line, and a reinforced concrete control tower located on the upstream side of the dam. Flows through the outlet conduit and supply line are controlled by manually operated sluice gates located in the control tower. This outlet system constitutes the emergency drawdown facilities for the dam.

Phase I Inspection Report written by KIMBALL (L ROBERT) AND ASSOCIATES EBENSBURG PA. and published by . This book was released on 1981 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chambers Dam appears to be in poor condition and poorly maintained. Erosion of the upstream slope has reduced the embankment crest to a width of 4 feet. Minor seepage was observed on the downstream slope of the dam, and a wet area was observed immediately beyond the toe of the dam. Brush and trees litter the downstream slope of the dam. No determination could be made as to the actual condition of the drainline culvert through the embankment. No determination could be made as to the condition or type of upstream closure on the culvert or whether the control is operable. The spillway located at the right abutment of the dam is in a deteriorating condition. Erosion exists along the right outside edge of the spillway wingwall. If the erosion is left unchecked, the potential for failure of the spillway and dam exists. The Chambers 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 1/2 PMF to PMF. Based on 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 less than 1% of the PMF without overtopping the embankment low spot.

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.

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 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kyle Dam consists of an earth embankment approximately 1000 feet long with a maximum height of 33 feet from the downstream toe and a crest width of 12 feet. The flood discharge facilities for the dam consist of two open channels, one located on each abutment. The 50-foot-wide rectangular concrete channel on the left abutment (looking downstream) constitutes the primary spillway of the reservoir. The 71-foot-wide rectangular concrete channel on the right abutment is the emergency spillway of the dam. The crest of the emergency spillway is about 0.9 foot above the crest level of the primary spillway, as measured during this inspection. The outlet works consist of a reinforced concrete intake tower, two 12-inch cast-iron supply pipes, and two 30-inch cast-iron outlet pipes. Pipes through the embankment are encased in concrete. Flow through the outlet pipes is controlled by manually sluice gates located in the intake tower. The two 30-inch outlet pipes constitute 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 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 D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . This book was released on 1980 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clover Dam consists of an earth embankment constructed around timber cribbing filled with stone and earthen materials. The dam has a crest length of approximately 550 feet with a maximum height of approximately 31 feet from the downstream toe. The crest width of the dam is about 25 feet with a downstream slope of 2.5H to 1V. A portion of the downstream slope near the left abutment is steeper (approximately 1H:1V). A steel sheet-pile wall exists along the upstream edge of the crest for the total length of the embankment. The sheet piling appears to be battered (approximately 1H:3V). The flood discharge facilities for the dam consist of an overflow spillway located at the center of the embankment. The steel sheet piling on the upstream face of the dam continues across the crest of the spillway. The spillway is approximately 60 feet long and is about 3-1/2 feet deep at the right abutment wall. The spillway discharge channel is a rectangular reinforced concrete channel. The channel is 61 feet wide at the overflow section and then converges uniformly to a width of about 40 feet at midheight of the embankment. The discharge channel terminates at a plunge pool at the toe level of the dam. Commonwealth inspection reports indicate that the spillway discharge channel was directly founded on timber cribbing.

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: Bigan Dam appears to be in poor condition and modifications to the dam have apparently been in progress for several years. The reservoir pool is maintained at a reduced level due to a directive from the Commonwealth pending the completion of design modifications to the structure. Due to the questionable condition of the earthen embankment section near the right abutment, the static stability of the structure is questionable. The spillway for the dam is a temporary structure, and a new spillway is planned at the dam. The owner should be urged to complete the construction of the facility as soon as possible. The completion of the structure should include an assessment of the earthen embankment section near the right abutment, and the stability of the section should be evaluated.
