This book was released on 1981 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, past performance, field surveys and calculations, Glenwood Lake Dam is judged to be in poor condition. The recommended Spillway Design Flood (SDF) for the size (small) and hazard classification (high) of the dam is between the one-half Probable Maximum Flood (1/2 PMF) and the full PMF. Based on the small size and storage capacity, it is judged that the SDF of 1/2 PMF is appropriate for the Glenwood Lake Dam. Under the present conditions, the spillway will pass approximately 10 percent of the PMF without overtopping the dam. Overtopping depths of 1.1 feet and 2.12 feet were calculated for flood magnitudes of 20% and 50% of the PMF, respectively. It was judged that the dam will begin to fail under an overtopping depth of one- foot. Because the present spillway capacity would not pass the SDF without overtopping the dam and failure of the dam would increase the downstream hazard to life and property, the spillway is rated as seriously inadequate and the dam is rated as unsafe, non-emergency. The facility is not properly maintained, as evidenced by the extensive growth of trees on the embankment and the condition of the outlet works valve pit. There is no warning system and evacuation plan in effect at the present time.

This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Lake Henry Dam is judged to be in good condition. The existing spillway can pass 60 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. If the embankments were raised 0.7 foot to their design elevation, the dam could pass the PMF with 0.05 foot of freeboard. The spillway capacity would then be rated as adequate. A low area between the two embankments acts as an auxiliary spillway. There is no stability analysis for the embankments. There is no evidence of significant problems threatening the embankments. The spillway weir is judged to be stable.

This book was released on 1979 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Rocky Glen Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The existing spillway can pass only 7 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. Because a portion of the masonry gravity dam is founded on earth and there are no erosion protection measures at the toe, it is assumed that the dam could not withstand the depth and duration of overtopping that would occur for the PMF or the 1/2 PMF. Failure of the dam would cause an increased hazard to loss of life downstream. As a whole, the dam is judged to be in fair condition. Stability studies performed as part of this report indicate that the dam does not have any significant deviations from the Office of the Chief of Engineers (OCE) guidelines for stability. Maintenance at the dam and operating facilities is inadequate. There is no program for regular inspection of the 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.

This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, Coleman Dam is judged to be in poor condition. In the absence of a spillway, the dam is subject to frequent overtopping. Based on the downstream hazard and in accordance with the recommended guidelines, the minimum selected Spillway Design Flood (SDF) for the facility is the 100-year flood. Results of the hydrologic and hydraulic analysis indicate that the peak discharge of the 100-year flood is 200 cfs. The existing facility will not pass the 100-year flood without overtopping the dam. Although the dam has withstood frequent overtopping since its construction, the maximum depth of past overtopping could not be verified. Therefore, in the absence of a spillway and based on the downstream hazard, the facility is rated inadequate. Although there is significant leakage and seepage through the dam, the available information is insufficient to evaluate its structural stability. The Dam is not properly maintained, as evidenced by the heavy growth of trees on the embankment and the numerous burrows on its downstream slope. (Author).

This book was released on 1979 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Dunmore No. 1 Dam is judged to be in good condition. The spillway can pass 84 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. Two culverts, immediately downstream of the dam, may provide significant tailwater effects at the dam. If the top of the dam were raised 0.4 foot to its design elevation, the spillway can pass 90 percent of the PMF. The spillway capacity would still be rated as inadequate. Because there is no analysis available, the structural stability of the masonry gravity spillway is unknown. The spillway right training wall does not have any significant deviations from the guidelines for stability. There is no evidence of instability on the embankment.

This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Sophia Dam consists of an earth embankment approximately 340 feet long with a maximum height of 29 feet from the downstream toe and a crest width of 9 feet. The upstream side of the dam is protected by a small amount of riprap and the downstream face is covered with grass. The flood discharge facilities for the dam consist of a concrete open-channel spillway located near the left abutment. The outlet facilities consist of a 12-inch-diamenter corrugated metal pipe extending through the embankment along the original streambed. Based on the evaluation of existing conditions, the condition of Lake Sophia Dam is considered to be unsafe/nonemergency due to seriously inadequate spillway capacity. The flood discharge capacity was evaluated according to to the recommended procedure and was found to pass approximately 15 percent of the PMF without overtopping the dam. Results of the breach analysis indicate that downstream damage would be significantly increased due to a dam failure.

This book was released on 1981 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Brown's Lake Dam is based upon visual observations made at the time of inspection, hydraulic and hydrologic computations and past operational performance. The inspection and review of data of the Brown's Lake Dam did not reveal any problems which would require emergency action. The dam appears to be in good condition and adequately maintained. Brown's Lake Dam is a high hazard-small size dam. The spillway design flood (SDF) for a dam of this size and classification is 1/2 PMF to the PMF. the PMF has been selected as the spillway design flood based on downstream potential for loss of life. The spillway and reservoir are capable of controlling the spillway design flood (PMF). Based on criteria established by the Corps of Engineers, the spillway is termed adequate. The following recommendations and remedial measures should be instituted as soon as possible. (1) A regularly scheduled maintenance program should be developed and implemented. (2) A warning system should be developed to warn downstream residents of large spillway discharges or imminent failure of the dam. (3) A safety inspection program should be implemented with inspections at regular intervals by qualified personnel. (4) The drainline valve should be operated on a regular basis.

Dziubek and published by . This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hathaway Pond Dam is located in Ararat Township, Susquehanna County, Pennsylvania. The reservoir was originally created to provide water for power purposes. The reservoir slopes are moderate with a good cover of vegetation. There are three ponds upstream from Hathaway Pond Dam on two tributary streams. The western stream contains Romobe Lake (PennDER I.D. No. 58-10) which is 1750 feet upstream from Hathaway Pond Dam. The eastern tributary contains Ball Lake and an unnamed smaller pond in series. Ball Lake is 2450 feet upstream and will retain considerable storage while the smaller unnamed pond was considered to have no effect on Hathaway Pond Dam. Two homes, a trailer, and township road are located 1800 feet downstream from Hathaway Pond Dam. These could suffer economic damage in the event of a dam failure.

This book was released on 1979 with total page 85 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, Summit Lake Dam is rated as unsafe, nonemergency, because the spillway capacity is seriously inadequate. The existing spillway can pass 26 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The failure of the dam would cause an increased hazard to loss of life downstream. As a whole, the dam is judged to be in fair condition. If the top of the dam were raised 0.1 foot to its design elevation, the spillway could pass 27 percent of the PMF. The spillway capacity would still be rated as seriously inadequate. There is no evidence of stability problems with the embankment. The masonry gravity section of the embankment has no significant deviations from the OCE guideline for stability, since the toe pressure is well below the allowable.
