This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenville Dam No. 3 is classified as a 'small' size, 'significant' hazard dam, with a recommended 1/2 PMF spillway design flood. Based on the review and evaluation of available design information, and visual observations of conditions as they existed on the date of the field reconnaissance, the general condition of Greenville Dam No. 3 is good. Seeps located at both downstream embankment junctions are not considered to represent a significant hazard to the dam at this time. However, a reasonable potential exists for the seeps to develop into a significant hazard. Periodic observation of the seeps by the dam owner is advised. Analysis using the HEC-1 Dam Safety Version computer program, indicates the spillway channel can pass a maximum of 43 percent PMF without overtopping the embankment crest. Spillway discharge capacity is assessed inadequate in accordance with guideline criteria.

This book was released on 1979 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little Shenango Dam (PA 490) is a homogeneous earth floodwater retarding dam designed by the U.S. Department of Agriculture, Soil Conservation Service. The dam has a crest length of 430 feet, a maximum height of 45 feet, a storage volume of 472 acre-feet at spillway crest level, and a storage volume of 19 acre-feet at normal pool level. The dam was found to be in generally poor condition at the time of inspection. The inspection did disclose potential problems with seepage and piping in the dam embankment and abutments. A detailed engineering investigation of seepage, piping, erosion, and structural stability of the dam should be initiated as expeditiously as possible. Hydraulic/hydrologic evaluations revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. The spillway is therefore considered 'adequate'.

Dziubek and published by . This book was released on 1980 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pine Run Dam is classified as a 'Small' size - 'Significant' hazard dam. The dam, owned by the Mercer County Commissioners, is used to reduce floodwater damages in the Little Shenango Watershed. The dam and appurtenant structure were found to be in good condition at the time of the inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, U.S. Army Corps of Engineers, for PHase I Inspection Reports, revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Pine Run Dam. The spillway is therefore considered to be 'adequate'. The visual inspection and review of information did not reveal any problems or deficiencies which require remedial action by the owners of the dam at this time. It is recommended that the owners continue their inspections and maintenance programs to maintain the dam in good condition. (Author).

This book was released on 1979 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saul Run Dam, a flood water retarding dam designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS), is also known by its SCS number PA-458. The homogeneous earth embankment has a crest length of approximately 1700 feet and a miximum hength///eight of about 40 feet. The dam crest at El. 1113.6 feet has a width of 16 feet. The upstream slope has an inclination of 3H:1V (horizontal:vertical) and an 8-foot wide berm at El. 1085 feet. The downstream slope with an inclination of 2.5H:1V also has an 8-foot wide berm at El. 1084 feet. A foundation cutoff trench with a base width of 12 feet, 1H:1V side slopes, a length of about 100 feet, and a depth of about 5 feet to bedrock was constructed in the valley bottom (Plate 5). Cutoff trenches of similiar cross-section were also constructed in the soil abutments (Plate 5). The outlet works (principal spillway in SCS terminology) consist of a reinforced concrete riser connected to a 24-inch diameter reinforced concrete pipe is located beneath the embankment in the valley bottom. The outlet pipe, with six reinforced concrete anti-seep collars, was installed on a concrete cradle founded on bedrock.

Y. Chen and published by . This book was released on 1979 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bradford City No. 3 Dam consists of a diaphragm earthfill embankment approximately 47 feet high and 770 feet long. A core wall consisting of mortar and sandstone blocks was constructed in the center of the embankment. The core wall extends 25 feet into each hillside and approximately 9 feet below the original ground surface at the deepest point in the center of the valley. The visual inspections and review of engineering data, performed in November 1978 through February 1979, indicate no serious deficiencies in the embankment requiring emergency attention. The dam was found to be in good overall condition at the time of inspection. However, the inspection revealed certain items of maintenance and rehabilitation necessary for the dam. Hydraulic/hydrologic evaluations revealed that the spillway will not pass the Probable Maximum Flood (PMF) without overtopping the dam. The spillway is considered 'inadequate' because the analysis indicated the spillway will pass a maximum of 45 percent of the PMF before overtopping the dam, and failure of the dam is not likely to occur under 50 percent PMF conditions.

A foundation drain is provided under the downstream portion of the embankment. A 4-foot wide trench was excavated in the foundation to depths varying from 3 to 10 feet. A 12-inch diameter perforated drainpipe is provided in the foundation drain with its outlet discharging into the impact basin. The principal spillway is located approximately 630 feet from the left abutment. The main features of the spillway are a pond drain, a reinforced concrete riser and a pipe conduit through the fill with an impact basin at the discharge end.

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.
