This book was released on 1980 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: YMCA Dam is an earthfill dam, 42 feet high and 608 feet long. The crest width is 9 feet. The upstream slope is 2.5H:1V and grass covered. The downstream slope was measured to be 2H:1V and grass covered. The reservoir drain consists of a 24 inch corrugated metal pipe with a concrete endwall located 270 feet from the left abutment. The spillway consists of a 42 foot long ogee section, 150 feet from the left abutment. The inspection and review of data of the YMCA Dam did not reveal any problems which require emergency action. The dam appears to be in fair condition. The seepage which was noted along the toe of dam should be monitored and evaluated by a professional engineer knowledgeable in earth dams. The evaluation should be implemented immediately. The spillway and reservoir are capable of controlling approximately 81% of the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed adequate.

Beck and published by . This book was released on 1980 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Railroad Creek Dam is a 34-foot-high zoned earth embankment about 1,170 feet long with an emergency spillway at the left end of the embankment. The embankment contains an impervious core constructed over a cutoff trench under the dam centerline. The principal spillway consists of a concrete drop inlet riser, 202 feet of 30 inch diameter reinforced concrete, steel cylinder pressure pipe, with seven anti-seep collars and an impact basin at the downstream toe. The reservoir drain is located at the base of the riser. Because of high pressure gas lines which cross the reservoir area, the pond drain gate is not closed and water is not normally impounded behind the dam. The emergency spillway is a trapezoidal channel excavated around the left end of the embankment. The dam and its appurtenant facilities are considered to be in good condition. Calculations indicate that the existing spillway systems are capable of passing the Probable Maximum Flood (PMF) without overtopping. Therefore, the spillway system is considered to be adequate.

Beck and published by . This book was released on 1980 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep Creek Dam is owned by the Montgomery County Commissioners and maintained by the Parks Department. The dam and reservoir are used for recreational purposes. The dam and its appurtenant facilities are considered to be in fair condition. The dam is classified as a Small size structure with a High hazard classification consistent with its potential in the event of sudden failure for extensive property and loss of life downstream along Perkiomen Creek. In accordance with criteria established by Federal (OCE) Guidelines, the spillway design flood for this 'Small' size dam and 'High' hazard classification is 0.5 to the full Probable Maximum Flood (PMF). As the total storage capacity is nearer the lower limited for the Small size classification, and as the watershed controlled by Deep Creek Dam is small compared to the watershed controlled by downstream knight Dam, the selected spillway design flood is 0.5 PMF. Hydrologic and hydraulic calculations indicate that the spillway structure is capable of discharging about 0.21 PMF without overtopping the embankment at the right abutment. If the right abutment and embankment were raised to the original design elevation, the spillway would be capable of discharging about 0.38 PMF without overtopping. The 0.4 PMF is judged to cause failure of the embankment by overtopping, but failure does not significantly increase the danger to human life or property; thus, the spillway rating for this structure is considered to be Inadequate but not Seriously Inadequate.

This book was released on 1981 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction data indicate that Quakake Dam is in fair condition. The limited spillway capacity is the primary deficiency which causes concern for the safety of this facility. The dam in its present condition is considered to be unsafe, non-emergency. In accordance with the guidelines provided, the spillway design flood (SDF) ranges between 1/2 the PMF to the full PMF. Based on the size of dam, the SDF selected was 1/2 the PMF. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass only 9% of the PMF prior to overtopping the embankment. Overtopping the dam could cause failure, which would lead to a significant increase in downstream loss of life and property damage. Therefore, the spillway for Quakake Dam is considered to be seriously inadequate.

This book was released on 1979 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Big Boulder Dam is owned by the Big Boulder Corporation and serves as a recreation lake and water supply for snow making at the lodge. The dam was built in the summer of 1957, and is classified as an 'Intermediate' size dam by virtue of its 1,971 acre-foot maximum storage capacity. Big Boulder Lake is formed by Dam A across Grass Lake Creek and Dam B, a saddle dam on the watershed divide. In the event that Dam B fails, extreme property damage and a possibility for the loss of life exists downstream along Swamp Run, thus classifying the structure as a 'High' hazard dam. The hydrologic and hydraulic calculations presented indicate that the spillway system for this structure is rated as 'Adequate' as it will pass the PMF. On the basis of the visual inspection on 11 May 1979, and review of available construction and design documentation, the dam and appurtenances of Big Boulder Reservoir appear to be functioning satisfactorily with the exception of undesirable seepage at the downstream toe of Dam A. The resident engineer's reports leave some question as to the quality of foundation preparation.

Beck and published by . This book was released on 1980 with total page 86 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 a Phase I investigation is to expeditiously identify 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 investigations, testing and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify the need for more detailed 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 1978 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, available records, calculations and past operational performance, Silver Creek Dam is judged to be in fair condition. The spillway and the low overbanks adjacent to the spillway have sufficient capacity to the Probable Maximum Flood (PMF) without overtopping the dam. Based on criteria established for these studies by the Department of the Army, Office of the Chief of Engineers (OCE), the spillway capacity is rated as adequate. The existing spillway and the adjacent overbanks can accommodate a flood with a peak inflow of 115 percent of the PMF peak flow. (Author).

This book was released on 1979 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: East Stroudsburg Dam is a 47.5 foot high earth and rock fill embankment with a concrete core wall. The dam is located across Sambo Creek and is about 740 feet long. The structure impounds a 57-acre lake with a 914 acre-foot normal storage capacity. Available records indicate that the core wall is founded in clay or hardpan. Upstream of the core wall, embankment materials consist of compacted soils. The upstream slope is protected with hand placed riprap. The slope is 2H:1V above elevation 867 (USGS Datum) and below elevation 867 the slope increases to 2.5H:1V. The compacted fill section downstream of the core wall has a 1H:1V slope and the overlying hand placed rock section has a slope of 2H:1V with a six foot berm at approximately elevation 873. The crest elevation is 893 with a measured width of 12 feet. The gatehouse is located about 320 feet from the right abutment. The best available section of this gatehouse is shown to Plate 5, Appendix E. The sluice gates are inside the gatehouse, one for the 24-inch intake pipe and one for the 24-inch discharge pipe. The intake is located at the upstream toe and the outlet discharges at the downstream toe into a rocklined channel.

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 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 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.
