This book was released on 1981 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in good condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is significant. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of the 100 year flood to one-half the Probable Maximum Flood (PMF). The recommended SDF for this structure is the 100 year flood. The spillway capacity is insufficent for passing the SDF peak inflow without overtopping the dam. The spillway, therefore, is considered to be inadequate. The following recommendations are presented for immediate action by the owner: (1) That provisions be made to increase the spillway capacity. (2) That the bare areas on the downstream slope be reseeded. (3) That the drop inlet structure be inspected for structural adequacy after the reservoir has been lowered. (4) That the struts in the spillway be removed and that the wooden waterway diversion poles be secured by other means. (5) That a formal surveillance and downstream warning system be developed for use during periods of high or prolonged rainfall. (6) That an operation and maintenance manual be prepared for guidance in the operation of the dam during normal and emergency conditions, and that a schedule be developed for the annual inspection of the dam and its appurtenant structures.

This book was released on 1981 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in fair condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is high. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of one-half the Probable Maximum Flood (PMF) to the full PMF. The recommended SDF for this structure is one-half the PMF. The spillway capacity is adequate for passing 29 percent of the PMF peak inflow without overtopping the dam. Failure of the embankment due to overtopping by one-half of the PMF would not significantly increase the risk to loss of life downstream. The spillway, therefore, is considered to be inadequate, but not seriously inadequate. Recommendations are presented for immediate action by the owner.

This book was released on 1980 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in good condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Due to the high potential for damage to downstream structures and possibly loss of life, the SDF is considered to be the PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store about 77 percent of the PMF prior to embankment overtopping. Consequently the spillway is assessed as being inadequate, but not seriously inadequate. Deficiencies noted by the inspection team included the following: (1) large trees rooted within the downstream embankment face; (2) a damaged and inadequate spillway discharge channel; and (3) a bent gate stem and partially obstructed outlet associated with the blowoff conduit.

This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Memorial Lake Dam was constructed in 1945 as a recreational facility for the Indiantown Gap Military Reservation. The 760 foot long rolled earthfill embankment has a maximum fill height of 37 feet above the original streambed. Reference is made to Appendix F, Plates III and IV, for a general plan and typical section. A cutoff trench was excavated along the centerline of the dam and a concrete cutoff wall was placed in this trench. A 110 foot long ogee spillway was excavated in the left abutment. It has a weir crest elevation of 430.0, which is 8 feet below the top of dam. The ogee discharges the water to an eight foot deep stilling basin. A control tower is located 12.5 feet upstream from the centerline dam. Flow through the 48-inch conduit is controlled inside the tower by a 48-inch sluice gate or by a gated weir also located inside the tower and near normal pool elevation.(Author).

This book was released on 1979 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ebenezer Dam is an earthfill structure, constructed in about 1820 by the Union Canal Company as a feeder for their canal. The embankment length is about 230 feet with a maximum height of 25 feet. The spillway chute, located in the right abutment, makes a sharp drop and bend about 55 feet from the centerline dam and then parallels the embankment abutment and toe and joins the original steambed near the left abutment of the embankment. An abandoned gate structure at the upstream toe of the dam provides an uncontrolled upstream discharge through a 20-inch cast iron pipe. This pipe is closed off at the downstream end by a 12-inch inoperable valve in a small stone /headwall structure. (Author).

This book was released on 1981 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in good condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is intermediate and the hazard classification is high. These classifications indicate that the Spillway Design Flood (SDF) should be the Probable Maximum Flood (PMF). The spillway capacity is adequate for passing 43 percent of the PMF peak inflow without overtopping the dam. The spillway, therefore, is considered to be inadequate, but not seriously inadequate. Some recommendations presented for immediate action by the owner are: (1) that measures shall be taken to provide an adequate spillway capacity, which shall include the raising of the embankment profile uniformly to at least its design crest elevation; (2) that the downstream toe and an area 20 feet beyond the toe be cleared on a regular basis of all brush, weeds and trees, permitting close observation of the seepage; and (3) that the slab joints in the spillway channel be filled with a joint material.

Andersen and published by . This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. 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 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 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this inspection is to determine if the dam constitutes a hazard to human life and property. The dam's location is Carroll Township, Perry County, U.S.G.S. Quadrangle - Newport, Pa. The general appearance of Negley Dam is good. The embankment appears to be well maintained, except for a small area at the downstream toe around the principal spillway pipe outlet. The principal spillway is a 34-inch drop inlet structure with an 18-inch outlet pipe. The emergency spillway, located in the left abutment, has a well defined channel.

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.

This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lake Kimberly Dam Location is Southwest Madison Township, Perry County U.S.G.S. Quadrangle - Andersonburg, Pa. The overall evaluation of the facilities indicates that Lake Kimberly Dam is in poor condition. The growth of trees, brush and weeds should be removed, and the upstream slope should be protected from wave action. The crest profile is irregular and should be brought to a uniform elevation higher than the emergency spillway elevation in order to prevent overtopping. The downstream slope should be repaired where the slough has occurred and where the outlet pipe has eroded the embankment. The outlet pipe should be extended beyond the downstream toe of the embankment, and a rock protected plunge pool should be constructed at the end of the outlet pipe.
