Phase I Inspection Report written by Chuan Yuan Chen and published by . This book was released on 1979 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: PA 474 (also referred to as PA No Name No. 35) was designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS) for floodwater detention. The dam consists of a zoned earth embankment, a vegetated earth emergency spillway channel, a riser intake with a 36-inch diameter outlet conduit, and a saddle dike located to the right of the main embankment. The crest length of the main embankment is 1640 feet. The maximum height of the dam at the original steambed is 30 feet. The dam crest is at E1. 1264.3 feet and the top width is 14 feet. The inclination of the upstream face is 2.5H;1V (Horizontal to Vertical) with a 10-foot wide berm at E1. 1242 feet. The downstream slope is 2.5h:1V. A filter trench was installed in the downstream prism of the embankment from original Station 4+92 to 9+77. A portion of the filter trench is provided with 6-inch diameter filter drainpipe. The two outlets of the filter drainpipes exit into the impact basin approximately 1 foot downstream of the baffle wall. To the right of the main embankment is a small knoll which separates the saddle dike from the main embankment. This knoll consists primarily of sandy silt (ML) soils and is approximately 540-feet long between the two embankments. The crest length of the dike is 670 feet and the maximum height is 9 feet. The crest width of the homogeneous embankment (dike) is 14 feet. The inclination of both the upstream and downstream slopes of the dike is 2.5h:1V. (Author).

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.

Pine Run Dam (NDI Number PA-00737, PennDER Number 43-55, SCS Number PA-491), Ohio River Basin, Pine Run, Mercer County, Pennsylvania, Phase I Inspection Report written by John A. 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).

Book excerpt: Lake Wilhelm Dam, also known by its U.S. Department of Agriculture, Soil Conservation Service (SCS) number PA 475, was built for flood control and recreation. The dam, which was designed by the SCS, is a zoned earth embankment with a crest length of approximately 500 feet and a maximum height of 41.5 feet. The upstream face has a slope of 3H:1V (Horizontal to Vertical) to E1. 1191.5 feet and a 2.5H:1V slope to the top of dam E1. 1211.5 feet. To increase structural stability, two 4-foot berms are located at E1. 1191.5 feet and 1194.5 feet, a 20-foot berm is at E1. 1189.0 feet, and a 10-foot berm is at E1. 1180.0 feet. The downstream face has a slope of 2.5H:1V and the crest width is 16 feet. (Author).

Washington County, Pennsylvania. Phase I Inspection Report written by John A. Dziubek and published by . This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: PA 480 was designed by the U.S. Department of Agriculture, Soil Conservation Service (SCS) for floodwater detention. The total length of the dam is 555 feet, including the emergency spillway on the right abutement; the maximum height of the dam is 66 feet. The principal spillway is a drop-inlet structure consisting of a two-stage reinforced concrete riser connected to a 30 inch diameter reinforced concrete outlet pipe. The low-level inlet on the concrete riser is a 9 inch high by 15 inch wide orifice; this inlet maintains the normal pool level. There is 25.1 acre-feet of storage at normal pool level, all of which is reserved for a 50-year accumulation of sediment. Hydraulic/hydrologic evaluations, 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 1/2 Probable Maximum Flood (1/2 PMF) to the PMF is required for PA 480. The 1/2 PMF was selected as the SDF. The spillway is therefore considered to be 'adequate'.

Phase I Inspection Report written by BAKER (MICHAEL) JR INC BEAVER PA. and published by . 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'.

Phase I Inspection Report written by ACKENHEIL AND ASSOCIATES INC PITTSBURGH PA. and published by . This book was released on 1980 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general condition of the Refuse Settling Basin is considered to be fair. This assessment is based on visual observations that indicate a possible inadequate margin of safety against slope failure of a high ground water level exists in Embankment A. The condition is not considered to represent an immediate threat to the structure because of the relatively low impoundment pool elevation. It should, however, be evaluated. If a high ground water does not exist in Embankment A, the facility can be considered to be in good condition. The structure is classified as an 'intermediate' size, 'high' hazard dam. Corps of Engineers guidelines recommend the Probable Maximum Flood (PMF) as the Spillway Design Flood for an 'intermediate' size, 'high' hazard dam. The visual inspection indicated several minor deficiencies in addition to the possible high ground water condition. The deficiencies can be corrected or improved through implementation of the following recommended evaluation, remedial, monitoring and/or maintenance efforts.

A 6-foot-high dike was constructed in a saddle area to the left of the emergency spillway channel. Tamarack Lake Dam 'B' is classified as a 'High' hazard-'Intermediate' size dam. The dam was found to be in good overall condition at the time of inspection. Hydraulic/hydrologic evaluations revealed that the spillways will pass the Probable Maximum Flood (PMF) without overtopping the dam. The spillways are therefore considered 'adequate.'
