This book was released on 1980 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, past operational performance, and consideration of the existing normal pool level, Wanamie Dam is judged to be in fair condition. The existing spillway is a gorge that was eroded when the spillway washed out in 1955. The spillway can pass the Probable Maximum Flood (PMF), which is the Spillway Design Flood (SDF), with 7.9 feet of freeboard. Based on the size and hazard classification of the dam, the recommended SDF varies between the 1/2 PMF and the PMF. The selected SDF is based on the criteria and the downstream conditions. The pool level at maximum PMF level is 5.2 feet below the normal pool level that existed prior to 1955. The spillway capacity is rated as adequate. This rating is dependent upon removal of the remains of the timber structure in the spillway. The only significant stability problem that exists at the embankment is a bulge near the left abutment of the embankment. The owner presently has no intention of returning the dam to its design condition because there is no present requirement for increased water supply storage at the dam. There are no functional emergency drawdown facilities at the dam. Maintenance of the dam is inadequate.

This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, and past operational performance, Laurel Run No. 2 Dam is judged to be in good condition. The spillway will pass about 7 percent of the Probable Maximum Flood (PMF) before overtopping of the dam occurs. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between the 1/2 PMF and the PMF. Based on the criteria and the downstream conditions, the SDF is the PMF. The spillway capacity is rated as inadequate. It is judged that the dam could withstand the depth and duration of overtopping that would occur for the PMF. Records show that the dam has withstood an overtopping of 7 feet. No stability problems were evident at the dam. Although there is significant leakage at the masonry joints in the dam, records show that the leakage has existed for at least 65 years without any detrimental effects on the dam. The leakage is judged not to be a hazard to the dam at present. The ability of the emergency drawdown valve to function is uncertain because it has not been operated recently.

Mihalcin and published by . This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harris Pond Dam is a combination earth, concrete and masonry structure approximately 10 feet high and 135 feet long, including spillway. It is located on Roaring Brook Creek in Ross Township, Luzerne County, Pennsylvania. The overall appearance of the facility suggests it to be in good condition. The only deficiency noted by the inspection team that requires immediate remedial attention was the areas exhibiting concrete deterioration. Flashboards (reportedly removed during significant storms) were observed in-place across the service spillway. Although generally considered undesirable, they appear, in this particular case, to be of little significance relative to the safe operation of Harris Pond Dam.

This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maple Lake Dam is an earthfill embankment 14.4 feet high and 283 feet long, excluding spillway. The emergency spillway is located at the left abutment, consisting of an earth channel having a trapezoidal cross section. The bottom width of the spillway at the reservoir outlet is 56 feet. A service spillway, consisting of a 12-inch riser pipe and an 8-inch diameter outlet pipe, is located approximately 100 feet from the right abutment. The outlet works was reported to consist of an 8-inch diameter asbestos cement pipe, extending upstream of the riser pipe to the reservoir and terminating with two sections of an 8-inch diameter vitrified clay pipe, having a concrete plug at the inlet. Based on visual inspection, the Maple Lake Dam is judged to be in good condition. Under the present conditions, the spillway will pass approximately 37 percent of the PMF. Should the top of the dam be restored to its design elevation, the spillway could pass the SDF without overtopping the dam.

Book excerpt: Lake Walter Dam is located on Spring Run, approximately one mile upstream of its confluence with Meshoppen Creek in Springville Township, Susquehanna County, Pennsylvania. The condition of Lake Walter Dam is considered to be good. The only significant condition noted which requires further attention is the lack of erosion protection in the emergency spillway discharge channel. The swampy condition at the toe of the dam is not considered to be significant at this time; however, the condition should be monitored to document if seepage is developing.

This book was released on 1980 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Pine Run Dam No. 1 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. Pine Run Dam No. 1 appears to be in poor condition. Severe deterioration of the downstream slope, in particular, the overflow section, exists. The concrete has extensive cracks, and deteriorated portions. Seepage is passing through portions of the dam and under the spillway slabs. The mortar between the masonry blocks on the exposed downstream slope has eroded. The concrete buttresses have severely deteriorated and show stress cracks. The stability analysis conducted for this study which was based on assumed strength parameters indicates that the dam is unstable with water levels corresponding to the top of the non-overflow section (elevation 949.0). Pine Run Dam No. 1 is a high hazard-intermediate size dam. The recommended spillway design flood (SDF) for this dam is the PMF. The spillway and reservoir are capable of controlling approximately 30% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. If Pine Run Dam No. 1 fails due to overtopping, the hazard to loss of life and property immediately downstream of the dam would be significantly increased from that which would exist just prior to the overtopping. Pine Run Dam No. 1 is classified as an unsafe non-emergency dam. (Author).

This book was released on 1979 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dam G is a homogeneous earthfill embankment with a concrete core-wall. The embankment is 490 feet long and 19 feet high at maximum section. There are two outlet works at the dam. The first outlet works, which is near the right end of the embankment, consists of a concrete intake structure, two 24-inch diameter cast-iron pipes, and a valve house. This outlet works is connected to the water supply system. The second outlet works, which is near the left end of the dam, is similar to the first except it consists of a single 24-inch diameter pipe. The second outlet works provides the emergency drawdown capability. The concrete chute spillway is at the left abutment of the dam. Its crest is 3.0 feet below the design elevation of the top of the dam and is 75 feet long. The approach channel is short and concrete paved. The exit channel is a continuation of the chute. A bridge extends across the spillway crest. It is supported by two piers.

This book was released on 1981 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam's location is Wright Township, Luzerne County, U.S.G.S. Quadrangle - Wilkes-Barre West, Pa. The overall appearance and general condition of the dam and appurtenances are fair. Based on visual observations, it is apparent that no maintenance of the dam has been performed for some time. The trees and brush should be removed from the embankment. The spillway crest, discharge channel and walls should be repaired. The spillway bridge and pier should also be rehabilitated or removed since the structure could block the spillway if it collapses. The embankment and spillway appear stable since no signs of movement were noted and the core wall and downstream slope are adequate.

Jeffrey Kimball and published by . This book was released on 1980 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Louise Dam appears to be in poor condition. Lake Louise Dam is a high hazard small size dam. The spillway design flood is in the range of 1/2 PMF to PMF. The spillway design flood was selected to be the PMF (probable maximum flood) based on downstream potential for loss of life and property damage. The spillway is capable of controlling approximately 45% of the PMF. The dam breach analysis indicated that a significant increase in the downstream potential for loss of life and property damage exists should the dam fail. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. The spillway exit and entrance channels are in poor condition. The heavy vegetation creates the potential for water infiltration and made visual inspection of the embankment difficult. Lake Louise Dam is classified as an unsafe non-emergency dam.

This book was released on 1979 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection is to determine if the dam constitutes a hazard to human life or property. The dam consists of a homogeneous earthfill embankment that is 680 feet long and 64 feet high at its maximum section. The main spillway is a drop spillway located near the left abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. One 12-inch by 21-inch uncontrolled orifice is located in the upstream face of the concrete riser with the orifice crest at El. 1227.0, which is 27 feet below design elevation of the top of the dam. The auxiliary spillway is an excavated channel at the right abutment of the dam. It is grass-lined except for portions that were excavated into rock. The hazard classification is high hazard. Downstream conditions indicate that a high hazard classification is warranted for PA-468 Dam. It is owned by the Susquehanna County Commissioners. Its purpose is for flood control.

Mihalcin and published by . This book was released on 1980 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Jean Dam is a zoned earth embankment approximately 26 feet high and 780 long, including spillway. The emergency spillway is an uncontrolled, rectangular, concrete and rock cut chute channel located at the right abutment. The crest of the spillway is 20 feet long and is spanned by a concrete bridge which supports a portion of the bituminous roadway that covers the embankment crest. Drawdown capability is provided by means of a 30-inch diameter cast iron blowoff pipe controlled at the inlet by a 30-inch diameter sluice gate. The facility consists of a main dam (Lake Jean Dam) and two appurtenant saddle dams (east and west dikes). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store about 73 percent of the PMF prior to overtopping the east dike. Thus, based on the screening criteria contained in the recommended guidelines, the spillway is considered to be inadequate, but not seriously inadequate. Should the saddle dams be regraded to their design elevation, the spillway would then pass floods in excess of the PMF and would be considered adequate.

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.

This book was released on 1979 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations, and past operational performance, and according to criteria established for these studies, No. 5 Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The spillway can pass 29 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. Failure of the dam would cause an increase hazard to loss of life downstream. As a whole, the dam is judged to be in fair condition. The spillway gravity weir does not have any significant deviations from the guidelines for stability, since the toe pressure is well below the allowable. There is no evidence of instability on the embankment.
