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).

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.

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).

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.

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.

Anderson and published by . This book was released on 1979 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Storage Dam consists of an earth embankment approximately 500 feet long with a maximum height of 36 feet from the downstream toe and a crest width of approximately 15 feet. The appurtenant structures of the dam consist of a combined primary and emergency spillway located on the left abutment (looking downstream) and outlet works near the right abutment. Based on the evaluation of the existing conditions, the condition of Storage Dam is considered to be good. Numerous seeps were observed along the left abutment, but these seeps are not considered to be a threat to the integrity of the embankment. However, a slump and an associated wet area were observed along the toe of the dam near the left abutment. This condition should be investigated and necessary repairs performed. The flood discharge capacity of the Storage Dam spillway was evaluated according to the recommended procedure and it was found to be 40 percent of the probable maximum flood (PMF) without overtopping the embankment. Therefore, according to the recommended criteria, the flood discharge capacity of the dam is classified to be inadequate.

This book was released on 1980 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Reynoldsville Storage Dam is considered to be unsafe/nonemergency due to seriously inadequate spillway capacity. The condition of the embankment is considered to be poor. The spillway structures were found to be significantly deteriorated. Extensive seepage on the order of 100 to 200 gallons per minute was observed seeping through the spillway structures. The abutment walls of the spillway were constructed about 2 feet below the mean dam crest elevation, posing a potential for erosion of the embankment and the abutment in the event of large flows through the spillway. The downstream face of the dam was found to be on a steep slope (approximately 1.5H to 1V) with swampy areas at the downstream toe level of the dam. The downstream end of the outlet pipe was found to be blocked by debris and siltation, indicating that it has not been functional for some time. In view of the above deficiencies and lack of any design information, it is considered advisable that the dam be evaluated in detail by a professional engineer to assess the structural integrity of the embankment and prepare and execute plans for the rehabilitation of the spillway structures and outlet facilities. According to the recommended criteria, small dams in the high hazard category are required to pass from 50 percent to full probable maximum flood (PMF). In view of the downstream damage potential the upper limit of the recommended range is considered to be applicable to this dam. The flood discharge capacity was evaluated according to the recommended criteria and was found to pass 20 percent of the PMF without overtopping the abutment walls of the spillway.

This book was released on 1979 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galion Bay Dam consists of an earth embankment approximately 400 feet long with a maximum height of 37 feet from the downstream invert of the outlet conduit and a crest width of 20 feet. Galion Bay Dam is one of the three dams which impound Lake Rene. The other two dams are Wolf Creek Dam, located at the west end of Lake Rene, and Lake Rene Dam, located on the east side of the reservoir. Lake Rene Dam, which was constructed in 1955, was the original dam at the site. Galion Bay Dam and Wolf Creek Dam were constructed in 1971 in conjunction with the enlargement of Lake Rene. The flood discharge facilities for Lake Rene consist of primary and emergency spillways associated with Galion Bay and Wolf Creek dams. The Galion Bay Dam flood discharge facilities are comprised of a drop inlet primary spillway located at the center of the embankment and an emergency spillway on the right abutment (looking downstream). The primary spillway structure consists of a single-stage reinforced concrete riser, a 36-inch-diameter reinforced concrete conduit, and a plunge pool at the downstream end of the outlet pipe. The emergency spillway is a 30-foot-wide trapezoidal earth channel excavated into the right abutment. The reservoir outlet pipe for the dam consists of a 15-inch steel pipe extending from the upstream toe of the dam to the drop inlet structure.
