Book excerpt: Greene-Dreher Dam is a 20-foot high earthern embankment, 1,000 feet long which impounds a 152 acre-foot flood water retention pool. Total estimated volume of fill is approximately 30,000 cubic yards. The zoned embankment was constructed on natural soils without a cutoff trench or a grout curtain. The embankment contains three material zones; Zone 1, a relatively impervious core of silt and and silty sand; Zone 2, composed of silty gravel and silty sand; and an outer shell of Zone 3 material, described as rock larger than 6 inches in diameter. The embankment crest is 12 feet wide at a design settled elevation of 2,036 feet, and both upstream and downstream slopes are 3H:1V. The downstream section of the embankment contains a filter blanket approximately 2 feet thick, 30 feet wide and 320 feet long. The filter blanket is drained by a 6-inch diameter perforated corrugated metal pipe connected to a 6-inch diameter pipe which outlets adjacent to the principal spillway outlet.

Phase I Inspection Report written by Frederick Futchko and published by . This book was released on 1981 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the criteria established for these studies, Freethy Dam is judged to be unsafe, nonemergency, because the spillway capacity is seriously inadequate. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies between 1/2 of the Probable Maximum Flood (PMF) and the PMF. Based on the size of the dam and reservoir, the 1/2 PMF is selected as the SDF. The existing spillway will pass only about 2 percent of the PMF before overtopping of the dam occurs. It is judged that the dam could not withstand the depth and duration of overtopping during storms of only 20 percent of the PMF. Failure of the dam would cause an increased hazard for loss of life downstream. Overall, the dam is judged to be in good condition.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1978 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suydam Dam is a 24 foot high homogeneous earth embankment, 508 feet long and impounds a 12.1-acre reservoir. The embankment contains a downstream crushed rock trench drain discharging through a 6-inch diameter corrugated metal drain. This pipe discharges at the downstream toe. The upstream slope to elevation 1,285.0 is protected with a 12-inch riprap layer over a 12-inch filter course. The upstream and downstream slopes are 3H:1V and 2H:1V, respectively. Except for riprapped surfaces, both slopes are covered with grass and Crownvetch. The crest is 12 feet wide with a settled design elevation of 1,298.0.

Phase I Inspection Report written by Frederick Futchko and published by . This book was released on 1980 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on criteria established for these studies, Lake Watawga Dam is judged to be unsafe, nonemergency, because the spillway capacity is seriously inadequate. The recommended Spillway Design Flood (SDF) for the size and hazard classification of the dam varies from 1/2 the Probable Maximum Flood (PMF) to the PMF. Based on the criteria and the downstream conditions, the selected SDF is the PMF. Based on existing conditions, the spillway will pass about 14 percent of the PMF before overtopping of the dam occurs. It is judged that the dam would fail during the PMF. Failure of the dam would increase the hazard for loss of life downstream. As a whole, the dam is judged to be in fair condition. Deficiencies exist that are considered to be indicative of potential stability problems for the spillway. There is no functional outlet works at the dam. Maintenance at the dam is inadequate.

Phase I Inspection Report written by and published by . This book was released on 1980 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This flood control dam consists of a 1000-foot-long earthfill embankment with a maximum height of 25 feet. Seven hundred fifty feet of the embankment crosses the valley, the other 250 feet ties the embankment to higher ground in the left abutment. The principal spillway is a drop inlet structure with an orifice opening and discharges through a 30-inch diameter pipe. This spillway is designed to handle a 100 year flood. For any larger floods the emergency spillway is required. This grassed earth spillway is located in the right abutment and has its design crest elevation 4.6 feet below the top of embankment. The emergency spillway has a channel bottom width of about 60 feet. Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in good condition. The spillway capacity is adequate to pass the PMF peak inflow without overtopping the dam.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1978 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cadjaw Pond Dam is owned by the Honesdale consolidated Water Co., and was once used as an emergency water supply source for the city and surrounding area. Currently, the dam has no immediate purpose for the water company except in the extreme event that water is needed as a supplemental source. The dam is in an obvious state of disrepair and severely neglected. Further, there are a large number of unknowns concerning the overall stability of the embankment. Until such time as appropriate studies are made and needed repairs performed, the dam should be considered unsafe. Based on this, seven recommendations are presented with the anticipation that it is desired to keep the structure and reservoir in service. If there is no need to maintain this structure, or if rehabilitative costs are excessive, an alternate solution would be to breach the structure under the guidance of a Professional Engineer, and allow the water level to reach the preexisting level of the natural lake.

Phase I Inspection Report written by GANNETT FLEMING CORDDRY AND CARPENTER INC HARRISBURG PA. and published by . This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on available records, visual inspection, calculations, and past operational performance, Lake Paupackan Dam is judged to be in fair condition. Considering the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between the 1/2 Probable Maximum Flood (PMF) and the PMF. The 1/2 PMF was, in this case, selected as the SDF. The spillway and reservoir, under existing conditions, will pass approximately 19 percent of the PMF before overtopping of the dam occurs. The spillway is, therefore, rated as inadequate.

Phase i Inspection Report written by Mary F. Beck and published by . This book was released on 1980 with total page 87 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 the 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.

Phase I Inspection Report written by and published by . This book was released on 1981 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, the Deckers Dam is judged to be in good condition. The spillway capacity of Deckers Dam is rated as adequate. The unknown condition of the valve, regulating flow through the outlet pipe, precluded assessment of the outlet works. Observations during pressure flow conditions in the outlet pipe are essential to the safety evaluation of the dam. A ready access to an operable valve, or other method of drawing down the reservoir level during emergencies, is required. Although the dam and appurtenances appear to be in good repair, there is no formal maintenance program for the facility. There is no warning system and evacuation plan in effect at the present time.

Phase I Inspection Report written by Hendrik Jongsma and published by . This book was released on 1980 with total page 76 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 the PMF. The spillway capacity is adequate for passing 51 percent of the PMF peak inflow without overtopping the dam. The spillway, therefore, is considered to be inadequate, but not seriously inadequate.

Phase I Inspection Report written by and published by . This book was released on 1980 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This flood control dam consists of a 550-foot-long homogeneous earthfill embankment with a maximum height of 31 feet above the streambed. The structure has two spillways. The principal spillway is a drop inlet structure and discharges through a 24-inch diameter pipe. An emergency spillway is constructed in the left abutment. This spillway consists of a grassed earth channel with a bottom channel width of 75 feet. The emergency spillway crest was designed to be 3.5 feet below the top of the dam. Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in good condition. The spillway capacity is adequate for passing the full PMF peak inflow without overtopping the dam.

Phase I Inspection Report written by CORPS OF ENGINEERS BALTIMORE MD BALTIMORE DISTRICT. and published by . This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction information indicate that Lake Quinn Dam is in fair condition. Deficiencies noted during the inspection included the lack of functional drawdown facilities and minor seepage through the masonry near the right abutment. Based on the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between 1/2 the Probable Maximum Flood (PMF) and the PMF. The 1/2 PMF has been selected as the SDF due to the size of the dam and reservoir, and the downstream conditions. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass only 3 percent of the PMF without overtopping the dam. 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 Lake Quinn Dam is considered to be seriously inadequate, and the dam is judged to be unsafe, non-emergency.

Ponderosa Pines Dam (NDI ID Number PA- 00304, DER ID Number 64-204), Delaware River Basin, Tributary to West Branch Lackawaxen River, Wayne County, Pennsylvania. Phase I Inspection Report written by and published by . This book was released on 1981 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, field survey and calculations, Ponderosa Pines Dam is judged to be in poor condition. As the spillway cannot pass the 1/2 PMF without overtopping at less than 1/2 PMF would cause failure which would significantly increase hazard to loss of life downstream, the spillway capacity is seriously inadequate and the facility is rated unsafe, nonemergency. Although there is no visible evidence of structural instability, the erosion of the downstream slope below the outlet pipe and the leakage below the toe of the dam are of concern. Should the observed erosion and leakage remain unchecked, it could, in time, affect the structural integrity of the dam. The invert elevation of the outlet pipe is but 2.1 feet below the spillway crest. There are no means to lower the reservoir level below the present level of the pipe inlet in case of emergency. The maintenance of the dam is limited to mowing grass on the crest and a portion of the upstream slope of the embankment. The balance of the dam is poorly maintained.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . This book was released on 1979 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warrington Dam is a 45 foot high zoned earth embankment, 1,600 feet long, with an emergency spillway at each end of the embankment. The embankment contains an impervious core constructed over a cutoff trench under the dam centerline. The core and cutoff trench are composed of materials classified as silty clays and clayey silts (Zone 1) and encompassed by less permeable materials classified as silty gravels (Zone 2). The upstream slope is 3H:1V with a 10 foot berm at approximately elevation 241.5, normal pool level. The downstream slope is 2.5H:1V with a 12 foot wide berm that serves as an access road along the downstream face of the embankment. The impervious Zone 1 core upstream slope is 2H:1V and the downstream slope is 1.5H:1V. The 14 foot wide embankment crest is at a design elevation of 272.9. Both upstream and downstream slopes are protected with grass. Embankment seepage is controlled by a drain trench near the downstream toe, which contains a 12-inch perforated drain pipe which discharges through the impact basin at the downstream toe.
