This book was released on 1981 with total page 64 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 Tremont Township, Schuylkill County U.S.G.S. Quadrangle - Pine Grove, Pa. The general appearance of the Black Creek Intake Dam is good, except that a heavy growth of trees covers the downstream slope of the embankment (Photograph No. 2). The slopes appear to be stable. A considerable amount of water was flowing through rocks just beyond the downstream toe near the spillway. This water appears to originate from the spillway channel. The overall visual evaluation of these facilities indicates that the dam is in good condition. The trees on the embankment should be removed. The observed steady seepage beyond the toe of the embankment adjacent to the spillway outlet channel has been a long standing condition (40 + or - years) and is not considered to be a serious problem at this time.

This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pole Run Dam No. 4 is a 30 foot high earthen embankment across Pole Run, a tributary of North Mahanoy Creek. The 780 foot long dam impounds a nine acre reservoir within an 0.58 square mile drainage basin. Very limited data exists regarding the physical features of the dam. The average measured downstream slope is 2H:1V, and the slope is covered with stone and vegetation. Since the average freeboard of the structure is less than one foot at normal pool level, the upstream slope could not be measured. A portion of the upstream slope is covered with stone, and this stone could be seen to extend at least two feet below the water and it is probable that it extends several feet below that elevation. The crest width ranges from 15 feet to 27 feet. The spillway is located at the right abutment, and consists of an open concrete channel with concrete retaining walls. The water supply intakes could not be inspected as they are below water and the pipes are buried in the embankment. The outlet pipes were inspected and three pipes were found. Near the toe of the dam, valves were located which are presumably used to control flow through the pipes.

This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Park Place Dam No. 3 is a 32 foot high earthen embankment across an unnamed tributary of North Mahanoy Creek. The 685 foot long embankment impounds a 109 acre-foot reservoir within an 0.27 square mile drainage basin. Since very limited data exists regarding the physical features of the dam and appurtenances, most of the features described herein were obtained from field measurements taken during this inspection. The downstream slope was measured to be 2H:1V and is covered with riprap and occasional vegetation, as shown on Photographs 7 and 8. The average upstream slope could not be measured as the very small freeboard between the crest of the dam and the normal pool prevented a reliable measurement. The upstream portion of the slope between the crest and to at least several feet below the waterline was covered with riprap. The crest width ranges from 10 to 12 feet and averages approximately 11 feet wide. A 10-inch water supply pipe is located at the base of the embankment. An eight-inch water supply line branches off in the downstream valve house at the downstream toe. Discharge through both lines is controlled by valves located in the valve house.

Andersen and published by . This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of a Phase I investigation is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general condition of the dam is based upon visual observations and review of available data. Detailed investigations and analyses involving topographic mapping, subsurface investigations, material testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the inspection is intended to identify any need for such studies which should be performed by the owner. 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 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 1979 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Hosensock Dam is a zoned earthfill dam designed by the U.S.D.A. Soil Conservation Service for flood control purposes. The principal features of the dam include the embankment, a concrete drop inlet type primary spillway and an emergency spillway section at the right abutment. The emergency spillway is constructed as an earth structure with the overflow section about six feet lower than the crest of the main embankment. The embankment crest design elevation is 1126 and its length is 795 feet from the left abutment to the emergency spillway. The height of the dam is 35 feet above the streambed. A two foot thick blanket drain is located under the downstream slope of the embankment. This blanket is composed of a filter material and is about 450 feet by 40 feet in plan dimension. The primary spillway is a reinforced concrete riser located at the upstream toe of the embankment near the center of the dam.

This book was released on 1979 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humboldt Dam is a homogeneous earthfill embankment with a masonry core-wall. The embankment is 974 feet long and 41 feet high at maximum section. A masonry gravity retaining wall, which acts as the spillway training wall, is at the right end of the embankment. The outlet works, which is near the middle of the embankment, consists of a masonry and corrugated metal intake structure with sluice gates, a 12-inch diameter cast-iron pipe(CIP), and a valve house at the toe of the dam. The intake structure is located on the upstream slope of the embankment; a bridge extends to it. Water supply pipes also extend from the intake structure. The masonry gravity spillway is at the right abutment of the dam. Its crest is 3.0 feet below the design elevation of the top of the dam and is 33.0 feet long. The spillway channel has a variable bottom width and a masonry gravity training wall on the left. The spillway channel extends along the right side of the valley.

Jeffrey Kimball and published by . This book was released on 1980 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kehly Run Dam No. 3 is an earth and rockfill dam 442 feet long and approximately 33 feet high. The spillway is an open cut channel located on the left abutment. The spillway crest has a total length of 35 feet and has an irregular bottom. Immediately downstream of Kehly Run Dam No. 3 is a swimming pool which forms tailwater on the dam. This swimming pool is formerly Kehly Run Dam No. 2. Upstream of Kehly Run Dam No. 3 are three reservoirs (Kehly Run Dams No. 4, 5, 6). Kehly Run Dam No. 3 appears to be in fair condition. Several areas of 'possible past instability' are apparent on the downstream slope. In addition, extensive seepage areas have been reported in the past but may be obscured by the tailwater. Maintenance of the dam and operating facilities is considered poor. The spillway design flood is the PMF (probable maximum flood). The spillway and reservoir are capable of controlling approximately 17% of the PMF without overtopping the embankment.

This book was released on 1979 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam consists of a zoned, earthfill embankment that is 590 feet long and 52 feet high at its maximum section. The main spillway is a drop spillway located near the right abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. The auxiliary spillway is an excavated channel along the left abutment of the dam. It is a grass-linked excavation in earth. Based on visual inspection, available records, calculations and past operational performance, PA-467 Dam is judged to be in good condition. The existing spillway can pass the Probable Maximum Flood(PMF) without overtopping of the dam. The spillway capacity is rated as adequate. There is a slope stability analysis for the embankment, and it indicates that the embankment has adequate factors of safety. There is no evidence of significant problems threatening the embankment.

This book was released on 1979 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Glen Brook No. 4 Dam is an earthfill dam 250 feet in length plus a 34 foot long spillway. It is 47 feet high above the streambed. This dam is the last of three such dams constructed in this area. The other two dams, identified as No. 1 and No. 2 are in series with and are located upstream from No. 4. This entire system of dams forms a source of reserve water supply for the Borough of Berwick. Based upon 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 intermediate and the hazard classification is high. The spillway capacity is inadequate to pass the PMF (Probable Maximum Flood) peak inflow without overtopping the dam. The spillway is capable of passing 10 percent of the PMF and is classified as seriously inadequate.

This book was released on 1980 with total page 96 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, Spring Brook Intake Dam is judged to be in good condition. 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. Based on the criteria and the downstream conditions, the selected Spillway Design Flood (SDF) at the dam is the Probable Maximum Flood (PMF). The existing spillway will pass about 53 percent of the PMF without overtopping of the dam. The spillway capacity is rated as inadequate. If the low area on the top of the dam were filled to the design elevation, the spillway would pass about 56 percent of the PMF, and it would still be rated as inadequate. The only stability problem evident at the dam is a bulge on the upstream slope of the embankment. The main and auxiliary spillway weirs have no significant deviations from the OCE guidelines for stability of gravity structures. There are two emergency drawdown facilities at the dam. One of these facilities is operational, but because of its small size, its ability to draw down the pool is marginal. The ability of the other facility to function is uncertain.

This book was released on 1979 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam, as it now stands, is a rockfill dam with a concrete core wall. This wall is founded on rock. The top of the core wall is at elevation 1432.5 which is 2.5 feet below the crest elevation of the embankment at elevation 1435.0. (Note: Project datum is 25 feet less than the USGS elevations). 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 hydrologic and hydraulic calculations indicate that the spillway for this dam has the capacity for passing 47 percent of the Probable Maximum Flood (PMF) without overtopping the embankment. Although 1/2 PMF will cause some overtopping, the depth of flow due to the overtopping is less than that judged to cause failure and therefore, the spillway, while inadequate, is not considered seriously inadequate.

Jeffrey Kimball and published by . This book was released on 1980 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Waste House Run No. 3 Dam is based upon visual observations made at the time of inspection, interviews with the owner and hydrologic and hydraulic analyses. Waste House Run No. 3 Dam is a high hazard-intermediate size dam. The dam is in fair condition. The spillway design flood is the PMF (Probable Maximum Flood). The spillway and reservoir are capable of controlling approximately 55% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate. Seepage is exiting at several locations at the toe of dam. One of these seepage areas is approximately 8 feet above the toe of dam on the upstream wall of the valve house. Significant movement of the downstream slope and walls of the valve house are in evidence and additional analyses are warranted.
