Beck and published by . This book was released on 1980 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sand Spring Run Dam is a recreational structure located in Hickory Run State Park and owned by the Commonwealth of Pennsylvania. The visual inspection and review of design and construction documentation indicate that the embankment and outlet structure are in good condition, the concrete weir is in fair condition, and the vegetation is in poor condition. The overall assessment is considered to be fairly good at the present time. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Small' size dam and 'Significant' hazard potential classification is the 100 Year Flood to one-half the Probable Maximum Flood (PMF). As the dam's total capacity in nearer the lower limit of the size classification and because of the limited number of occupied structures downstream, the 100 Year Event would be an adequate spillway design flood. However, one-half the PMF has been used in this case because of the actual spillway capacity. Hydrologic and hydraulic computations presented in Appendix D indicate the spillway is capable of passing the full PMF without overtopping the embankment, resulting in an 'Adequate' spillway classification for this dam.

This book was released on 1979 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pine Run Dam is a homogeneous embankment with an impervious cutoff trench beneath the centerline of the embankment. The dam is approximately 2,700 feet long and the height, measured from the stream bed to the crest, is 31.8 feet. Embankment fill was obtained from emergency spillway excavation and borrow areas within the reservoir. Zone I materials used in the cutoff trench are classified as low plastic silts, and Zone 2 materials are slightly less plastic but still classified as low plastic silts. The embankment internal drainage system discharges through the sidewalls of Saint Anthony's Falls (SAF) stilling basin at the downstream toe. The upstream slope is 3H:1V and the downstream slope is 2.5H:1V. The crest is 14 feet wide at elevation 287.8. The upstream slope has a 15 foot wide berm at approximately elevation 265, the normal sediment pool level.

Beck and published by . This book was released on 1980 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spring Mill Dam, built in 1889 and 1900, is owned by Northampton Borough Municipal Water Authority. The dam and reservoir are currently used as a secondary water supply for Northampton Borough, Pennsylvania. The dam and its appurtenant facilities are considered to be in good condition. The dam is classified as a Small size structure with a Significant hazard classification, consistent with its appreciable economic loss and possible loss of life in the event of failure. In accordance with criteria established by Federal (OCE) Guidelines, the spillway design flood for this Small size dam and 'Significant' hazard classification ranges from the 100 year event to 0.5 PMF (Probable Maximum Flood). As height of this dam is near the lower limit for small size dams, and the total capacity is less than one-third the upper limit, the selected spillway design flood is the 100 year event. Hydrologic and hydraulic computations presented in Appendix D indicate that the structure will not pass the 100 year event without overtopping. It is further assessed that the 100 year event would not cause failure or significantly increase the potential for excessive property damage and loss of life downstream of the dam. Therefore, the spillway systems of this structure are considered to be Inadequate but not Seriously Inadequate.

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.

This book was released on 1979 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mud Run Dam was designed and constructed in 1879 by the Philadelphia and Reading Coal and Iron Company. It was described in a 1914 report as an earthfill structure 1,124 feet in length. Very little information could be obtained as to the original construction. It was reported that the ground surface was well plowed to form a good bond with the fill and that the material, which was a mixture of clay and disintegrated conglomerate, was laid in layers and rolled. The dam was practically rebuilt in 1903 by adding to the then existing structure. The centerline was moved 16 feet downstream and the dam crest was increased from 8 feet to 24 feet in width and raised five feet in elevation. The downstream slope was changed from 1-1/2H to 1V to 2H to 1V and both slopes were paved with riprap. The material used in the enlargement was clay and disintegrated conglomerate which was laid in layers from 6 inches to 8 inches and rolled. A concrete core wall five feet wide on top and ten feet wide at the bottom was carried through a previous layer of underlying sand and gravel.
