Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . 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.

Phase I Inspection Report written by WOODWARD-CLYDE CONSULTANTS PLYMOUTH MEETING PA. and published by . 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.

Phase I Inspection Report written by KIMBALL (L ROBERT) AND ASSOCIATES EBENSBURG PA. and published by . This book was released on 1980 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Mahanoy Dam No. 2 is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. Mahanoy Dam No. 2 appeared to be in poor condition. Vegetation consisting of brush and small trees were observed on the upstream and downstream slopes. Erosion was noted on the downstream embankment near the maximum section of the dam. Several wet areas were located on the downstream face of the embankment during the inspection. One seepage point was noted at the right abutment contact and two other seepage points were observed near the left abutment. The reservoir drain valves have not been operated in the recent past. Maintenance of the dam and operating facilities is considered poor. Mahanoy Dam No. 2 is a high hazard-small size dam. The spillway design flood is the 1/2 PMF to PMF (Probable Maximum Flood). Based on the downstream potential for loss of life the spillway design flood for this dam has been selected as the PMF. Mahanoy Dam No. 2's spillway is capable of controlling approximately 12% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. If Mahanoy Dam No. 2 should fail due to overtopping, hazard to loss of life and property downstream of the dam would be significantly increased from that which would exist prior to the overtopping. Mahanoy Dam No. 2 is classified as unsafe, non-emergency.

High Vista, Inc., Susquehanna River Basin, Little Sugarloaf Creek, Schuylkill and Luzerne Counties, Pennyslvania, Phase I Inspection Report written by GANNETT FLEMING CORDDRY AND CARPENTER INC HARRISBURG PA. and published by . This book was released on 1978 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, available records, calculations and past operational performance, Lake Susquehanna Dam is judged to be in good condition. However, the spillway will not pass the Probable Maximum Flood (PMF) without overtopping the dam. If Lake Susquehanna Dam should be overtopped, it would probably fail by embankment erosion. If Lake Susquehanna Dam should fail due to overtopping, the hazard to loss of life downstream from the dam would be significantly increased from that which would exist just prior to overtopping. 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 inadequate. One-half the PMF is less than the spillway capacity; therefore, based on the OCE criteria, the spillway is not rated as seriously inadequate.

Phase I Inspection Report written by Frederick Futchko and published by . 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.

Phase I Inspection Report written by Hendrik Jongsma and published by . 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.

Phase I Inspection Report written by KIMBALL (L ROBERT) AND ASSOCIATES EBENSBURG PA. and published by . This book was released on 1980 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Fishpond Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. The inspection and review of data of Fishpond Dam did not reveal any problem which requires emergency action. The dam appears to be in poor condition mainly because of extensive seepage which appears to be increasing. A monitoring program developed by a professional engineer knowledgeable in earth dams should be implemented immediately. Fishpond Dam is a high hazard-small size dam. The SDF for a dam of this size and classification is 1/2 PMF to PMF. Based on the downstream potential for loss of life and property damage the spillway design flood has been selected as the PMF (Probable Maximum Flood). The spillway and reservoir are capable of controlling the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed adequate. (Author).

Duck Pond Dam (NDI ID Number PA-00379, DER ID Number 35-98), Susquehanna River Basin, Tributary to South Branch Tunkhannock Creek, Lackawanna County, Pennsylvania. Phase I Inspection Report written by and published by . This book was released on 1981 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available data indicate that Duck Pond Dam is in fair condition. The lack of embankment protection from spillway flows and the inadequate spillway capacity are the primary deficiencies which cause concern for the safety of this dam. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for this facility is in the range of the 100 year flood to 1/2 the Probable Maximum Flood (PMF). Based on the size of the dam and degree of downstream hazard, the selected SDF is the 100 year flood. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and outlet works discharge capacity will not pass the SDF (100 year flood) prior to overtopping the embankment. In accordance with the criteria outlined and evaluated in Section 5.5 of this report, the discharge capacity for Duck Pond Dam is considered to be inadequate.
