Phase I Inspection Report written by Hendrik Jongsma and published by . This book was released on 1981 with total page 82 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 one-half the PMF. The spillway capacity is adequate for passing 23 percent of the PMF peak inflow without overtopping the dam. Overtopping by the SDF is expected not to cause failure of the dam. The spillway, therefore, is considered to be inadequate, but not seriously inadequate. Some recommendations presented for immediate action by the owner are: (1) that measures shall be taken to provide an adequate spillway capacity, (2) that the cracked spillway slab be repaired, (3) that the downstream end of the spillway be protected from washouts during large discharges, (4) that the upstream gates be maintained and operated on a regular basis, and (5) that the downstream blow-off valves be maintained and operated on an annual basis.

Phase I Inspection Report written by BERGER ASSOCIATES INC HARRISBURG PA. and published by . This book was released on 1979 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nesquehoning 4th Hollow Reservoir Dam originally known as the Broad Run Dam is a homogeneous earthfill dam with a maximum height of 51 feet above the downstream toe. The length of the earthfill is 300 feet. A 50-foot wide spillway is located in the right abutment. This spillway is an ogee type weir having a crest elevation 8.5 feet below the top of the spillway abutment walls. The forebay walls, spillway chute and stilling basin are all formed with concrete walls and slabs. An intake structure is located at the toe of the upstream slope of the embankment and has 4 sluice gates; three for water supply intake and one for drawdown purposes. The conduit through the embankment is horseshoe shaped and has a well defined riprap protected downstream channel. At the exit of the conduit is a small basin with energy dissipators. The water supply intake is through a 16-inch C.I. pipe encased in concrete. (Author).

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: 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.

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 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.

Pleasant Valley West Property Owners Association. 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 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.

Phase I Inspection Report written by Hendrik Jongsma and published by . This book was released on 1981 with total page 69 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 poor condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is significant. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of the 100 year flood to one-half the Probable Maximum Flood (PMF). The recommended SDF for this structure is the 100 year flood. The spillway capacity is not adequate for passing the SDF peak inflow without overtopping the dam. The spillway is considered to be inadequate, but not seriously inadequate. Some recommendations presented for immediate action by the owner are: (1) that measures shall be taken to provide an adequate spillway capacity, which shall include the raising of the embankment profile to at least the design crest elevation, (2) that the embankment be cleared of all trees, brush and weeds under the direction of a professional engineer, experienced in the design and construction of earthfill dams, and (3) that access above the floodplain be provided for surveillance.

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 BERGER ASSOCIATES INC HARRISBURG PA. and published by . This book was released on 1979 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Towamensing Trials Dam is a 38 foot high zoned earthfill dam with an embankment length of about 3200 feet. Impervious material forms the upstream section of the embankment and has a surface slope of 3H to 1V. Random fill makes up the remaining portion of the embankment and forms a downstream slope of 2.5H to 1V. An internal drainage system includes a vertical stone drain 30 inches in width over the major length of the embankment. This vertical drain connects to a horizontal blanket drain which discharges into a 12-inch diameter perforated drain pipe just beneath the downstream toe of the embankment. A five foot deep key trench of impervious soil is located at the upstream toe of the embankment. This trench has a bottom width of 30 feet. The spillway, located at the left abutment, is a 50 foot wide concrete ogee section with a crest elevation of 1,645. Design crest elevation of the embankment is 1650.5. The outlet channel for the spillway is paved with concrete and has concrete training walls extending to a point 300 feet downstream from the spillway.

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 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction information indicate that Bronson Pond Dam is in fair condition. The primary deficiency noted during the inspection was the lack of any spillway or outlet facilities for the dam. Based on the size and hazard classification of the dam, the recommended Spillway Design Flood (SDF) varies between the 100-year flood and one-half the Probable Maximum Flood (PMF). Based on the size of the dam and reservoir, and the downstream conditions, the 100-year flood has been selected as the SDF. The hydrologic and hydraulic computations indicate that the combinations of reservoir storage and overflow discharge capacity pass the 100-year flood without overtopping the dam. For this reason, the overflow capacity for Bronson Pond Dam is considered to be inadequate.

Phase I Inspection Report written by Mary F. 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.

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: 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.
