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 1980 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is prepared under guidance contained in the Recommended Guidelines for Safety Inspection of Dams, for Phase I Investigations. The purpose of the Phase I investigation is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general condition of the dam is based upon available data and visual inspections. Detailed investigation, and analyses involving topographic mapping, subsurface investigations, testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify any need for such studies. In reviewing this report, it should be realized that the reported condition of the dam is based on observations of field conditions at the time of inspection along with data available to the inspection team. In cases where the reservoir was lowered or drained prior to inspection, such action, while improving the stability and safety of the dam, removes the normal load on the structure and may obscure certain conditions which might otherwise be detectable if inspected under the normal operating environment of the structure.

This book was released on 1981 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dam's location is Borough of Mt. Holly Springs, Cumberland County U.S.G.S. Quadrangle - Mt. Holly Springs, Pa. The general appearance of Upper Mt. Holly Dam is poor. The earth embankment is overgrown with brush and trees and the slopes are uneven. The riprap at the downstream side of the spillway has several voids and several trees are growing in this area. The reservoir is silted for most of its storage area at normal pool elevation. The drawdown sluice gate leaks and is inoperable. The overall evaluation of these facilities indicates that Upper Mt. Holly Dam is in poor condition. The growth of brush and trees on the embankment and in the downstream area of the spillway should be removed. After this clearing, the embankment should be inspected for seepage and signs of instability. The embankment should be made level and should be protected against erosion with a good grass mat. The riprap at the downstream side of the spillway should be repaired.

Quadrangle - Mt. Holly Springs, Pa. The overall visual evaluation of the facilities indicates that the Wolff Farm Dam is in good condition. However, it is strongly recommended that the downstream slope be provided with a more stable cover. The discharge through the emergency spillway should be directed away from the embankment and the source of the settlement over the 12-inch outlet pipe should be identified and the condition corrected. The rock protection at the outlet pipe should be rearranged so as not to block the open end of the pipe.

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.

This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pole Run Dam No. 4 is a 30 foot high earthen embankment across Pole Run, a tributary of North Mahanoy Creek. The 780 foot long dam impounds a nine acre reservoir within an 0.58 square mile drainage basin. Very limited data exists regarding the physical features of the dam. The average measured downstream slope is 2H:1V, and the slope is covered with stone and vegetation. Since the average freeboard of the structure is less than one foot at normal pool level, the upstream slope could not be measured. A portion of the upstream slope is covered with stone, and this stone could be seen to extend at least two feet below the water and it is probable that it extends several feet below that elevation. The crest width ranges from 15 feet to 27 feet. The spillway is located at the right abutment, and consists of an open concrete channel with concrete retaining walls. The water supply intakes could not be inspected as they are below water and the pipes are buried in the embankment. The outlet pipes were inspected and three pipes were found. Near the toe of the dam, valves were located which are presumably used to control flow through the pipes.

Beck and published by . This book was released on 1980 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mill Water Pond Dam is owned by the Bethlehem Mines Corporation. The dam was originally built as an industrial water supply dam for the Grace Mine. As the mine is no longer in operation, water from the reservoir is no longer used. The dam and its appurtenant facilities are considered to be in good condition. The dam is classified as a Small size structure with a High hazard classification, consistent with the dam's location immediately above an occupied dwelling and above commercial buildings and other residences farther downstream on Conestoga Creek. In accordance with criteria established by Federal (OCE) Guidelines, the spillway design flood for this Small size dam and High hazard classification is one-half to the full Probable Maximum Flood (PMF). As the dam height and total capacity are near the lower limit of the size classification, the selected spillway design flood is one-half the PMF. Mining of the deep iron ore body has caused extensive subsidence. The mine waste rock is disposed of downstream of the subsidence area. Therefore, currently, Mill Water Pond intercepts surface runoff only from about 0.31 square mile immediately above the dam. Hydrologic and hydraulic computations presented in Appendix D indicate the maximum spillway capacity is greater than the peak PMF inflow from the reduced watershed. Therefore, the spillway system of this structure is considered to be Adequate.

Beck and published by . This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Placid Lake Dam is owned by the Holiday Pocono Civic Association, Inc. The dam and reservoir are used for recreational purposes. The dam was built as part of a residential community and was completed in 1963. Visual inspection indicates that the spillway system of Placid Lake Dam is in fair condition. It is recommended that the following measures be undertaken immediately. (1) A detailed hydrologic/hydraulic investigation should be performed to determine the best method of increasing the spillway capacity. (2) The flashboard structure should be permanently removed from the top of the spillway drop inlet. (3) An investigation should be made into the actual cause of the apparent piping voids in the vicinity of the inlet conduit. (4) The spillway conduit joints should be sealed and the two downstream pipe lengths should be monitored for possible horizontal movement. (5) Erosion of the upstream face should be halted and the damaged embankment repaired. (6) The inlet sluice gate and the reservoir drain gate valve should be lubricated and exercised on a regular basis to insure their operational status. (7) All trees and brush should be removed from the downstram embankment face, the embankment returned to its original condition, and measures taken to establish a good stand of vegetation. (8) The rock dam in the diversion channel should be removed.

Mihalcin and published by . This book was released on 1979 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection and hydrologic/hydraulic analysis the overall condition of the facility is considered to be fair. The size classification of the facility is small and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Results of the hydrologic/hydraulic analysis indicate the facility will discharge and/or store only 24 percent of the PMF prior to overtopping of the embankment. Overtopping is expected to cause embankment failure, with the breaching analysis indicating that failure will probably result in an increase to potential for loss of life downstream of the facility. Therefore, the spillway system is considered to be seriously inadequate, and the facility unsafe, non-emergency. Deficiencies noted by the inspection team included seepage and swamp-like conditions immediately downstream of the embankment toe and around the outlet conduit, heavily overgrown outlet and spillway discharge channels, an erosion ditch extending from the right abutment hillside to the downstream embankment toe along the embankment-abutment contact, deteriorated spillway concrete, several unvegetated areas along the embankment and adjoining spillway dike, and a submerged outlet conduit riser and control valve.
