This book was released on 1981 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Brown's Lake Dam is based upon visual observations made at the time of inspection, hydraulic and hydrologic computations and past operational performance. The inspection and review of data of the Brown's Lake Dam did not reveal any problems which would require emergency action. The dam appears to be in good condition and adequately maintained. Brown's Lake Dam is a high hazard-small size dam. The spillway design flood (SDF) for a dam of this size and classification is 1/2 PMF to the PMF. the PMF has been selected as the spillway design flood based on downstream potential for loss of life. The spillway and reservoir are capable of controlling the spillway design flood (PMF). Based on criteria established by the Corps of Engineers, the spillway is termed adequate. The following recommendations and remedial measures should be instituted as soon as possible. (1) A regularly scheduled maintenance program should be developed and implemented. (2) A warning system should be developed to warn downstream residents of large spillway discharges or imminent failure of the dam. (3) A safety inspection program should be implemented with inspections at regular intervals by qualified personnel. (4) The drainline valve should be operated on a regular basis.

Download or read book National Dam Inspection Program. Brown's Lake Dam (NDI ID Number PA-00630, DER ID Number 45-108). Delaware River Basin, Stony Run, Monroe County, Pennsylvania. Phase I Inspection Report written by Frederick Futchko and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on avaliable records, visual inspection, calculations, and past operational performance, Brown's Lake Dam is judged to be in poor condition. Based on the size and hazard classification of the dam, the recommended Spillway Design Flood is the Probalble Maximum Flood (PMF). The spillway can pass about 82 percent of the PMF. Since the dam cannot pass the PMF but can pass the 1/2 PMF, the spillway capacity is rated as inadequate. Deficiencies exist that are considered to be pertinent to the stability of the dam. The deficiencies include the following: seepage, steep slopes, a depression on the top of the dam, growth of trees on the dam, and holes and a depression on the downstream slope of the dam. The type of design and methods of construction increase the concern for the deficiencies. The condition of the outlet works is unsatisfatory. There are no upstream closure facilities. Maintenance of the dam is inadequate. (Author).

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Sophia Dam consists of an earth embankment approximately 340 feet long with a maximum height of 29 feet from the downstream toe and a crest width of 9 feet. The upstream side of the dam is protected by a small amount of riprap and the downstream face is covered with grass. The flood discharge facilities for the dam consist of a concrete open-channel spillway located near the left abutment. The outlet facilities consist of a 12-inch-diamenter corrugated metal pipe extending through the embankment along the original streambed. Based on the evaluation of existing conditions, the condition of Lake Sophia Dam is considered to be unsafe/nonemergency due to seriously inadequate spillway capacity. The flood discharge capacity was evaluated according to to the recommended procedure and was found to pass approximately 15 percent of the PMF without overtopping the dam. Results of the breach analysis indicate that downstream damage would be significantly increased due to a dam failure.

Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1980 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Big Brown Dam consists of an earth embankment approximately 290 feet long with a maximum height of approximately 37 feet from the downstream toe, and a crest width in the range of 8 to 11 feet. The downstream slope of the dam is 1-1/2 horizontal to 1 vertical and is protected with well-established grass. The upstream slope is protected by riprap extending to the crest level of the dam. The flood discharge facilities for the dam consist of a primary spillway incorporated into the outlet facilities and an open channel emergency spillway located on the right abutment. The outlet facilities consist of a 20-inch cast-iron supply line and a 20-inch cast-iron blow-off pipe. Based on the evaluation of the existing conditions, the condition of Big Brown Dam is considered to be poor. Extensive swampy areas were observed along the toe of the dam. This condition, together with the steep downstream slope of the embankment raises concern as to the continued stability of the embankment. The flood discharge capacity of the dam was found to be at the lower limit of the recommended spillway capacity range of 50 percent to full PMF relative to the size and hazard classification of the dam.

Longford Lake Dam (NDI ID Number PA- 00898, DER ID Number 58-137), Susquehanna River Basin, Tributary to Choconut Creek, Susquehanna County, Pennsylvania. Phase I Inspection Report written by and published by . This book was released on 1981 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction data indicate that Longford Lake Dam is in good condition. In accordance with the guidance provided, the spillway design flood (SDF) ranges between 1/2 the PMF and the full PMF. Based on the size and extent of downstream hazard for the dam, the SDF selected for this facility was the PMF. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass 88% of the PMF prior to overtopping the embankment. Therefore, in accordance with the recommended criteria for Phase I inspections, the spillway for Longford Lake Dam is considered to be inadequate.

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 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Brown Creek 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 Brown Creek Dam appears to be in fair condition. The erosion on the crest and downstream embankment in the area of the principal spillway and along the wingwall of the emergency spillway crest should be repaired. Because the reservoir was dry (as is the normal condition) no determination as to potential wet zones or seepage areas could be made. Maintenance of the dam and operating facilities is considered fair. The Brown Creek Dam is a high hazard-small dam. The recommended spillway design flood (SDF) for this dam is the 1/2 PMF to PMF. Based on the potential for downstream loss of life, the spillway design flood has been selected as the PMF. The spillway and reservoir are capable of controlling approximately 80% of the PMF without overtopping the embankment (low spot). Based on criteria established by the Corps of Engineers, the spillway is termed inadequate.

Phase I Inspection Report written by and published by . This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maple Lake Dam is an earthfill embankment 14.4 feet high and 283 feet long, excluding spillway. The emergency spillway is located at the left abutment, consisting of an earth channel having a trapezoidal cross section. The bottom width of the spillway at the reservoir outlet is 56 feet. A service spillway, consisting of a 12-inch riser pipe and an 8-inch diameter outlet pipe, is located approximately 100 feet from the right abutment. The outlet works was reported to consist of an 8-inch diameter asbestos cement pipe, extending upstream of the riser pipe to the reservoir and terminating with two sections of an 8-inch diameter vitrified clay pipe, having a concrete plug at the inlet. Based on visual inspection, the Maple Lake Dam is judged to be in good condition. Under the present conditions, the spillway will pass approximately 37 percent of the PMF. Should the top of the dam be restored to its design elevation, the spillway could pass the SDF without overtopping the dam.

Phase I Inspection Report written by and published by . This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The condition of Bel-Air Lake Dam is considered to be unsafe/ nonemergency due to a seriously inadequate spillway capacity. The overall condition of the dam is considered to be fair. Although at this time no signs of significant distress were observed, it appears that the center of the dam has significantly settled. The design drawings show the design freeboard to be five feet, but the available freeboard is only approximately two feet. It also appears that fill has been placed on the downstream slope, increasing the crest width from the design value of 10 feet to about 30 feet near the center line of the dam and greater than 50 feet near the left abutment. The dam has no functional low level outlet facility.

Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1981 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perrins Marsh Dam, which is also known as Brown's Pond Dam or Schoonover's Lake, consists of a six-foot-high stone wall, backed by earth fill on the upstream side. In its present configuration, the dam appears to be about 50 to 60 feet long, with a 28-foot-long segment forming the overflow section of the dam. The overflow section is capped with a six-foot-wide concrete slab which appears to be about one foot thick. The earth fills flanking the overflow section gradually merge into the natural abutments with no discernible embankment-abutment junction. The dam does not appear to have any low level outlet facilities. It appears that this dam was constructed at the outlet of a natural lake to raise the lake level. The dam is classified to be in the significant hazard category. Below the dam, Whitelock Creek flows about 150 feet, falls over a stone wall, then flows under a bridge. A house located downstream of the bridge is considered to be in the floodplain of the creek. The stream flows adjacent to a rural residential area for approximately one mile, and then discharges to an essentially uninhabited valley. It is estimated that a failure of this dam would likely cause damage to the downstream bridges and property in the rural residential area. Loss of a few lives is considered possible.

Tributary of Messhoppen Creek, Susquehanna County, Pennsylvania. Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Walter Dam is located on Spring Run, approximately one mile upstream of its confluence with Meshoppen Creek in Springville Township, Susquehanna County, Pennsylvania. The condition of Lake Walter Dam is considered to be good. The only significant condition noted which requires further attention is the lack of erosion protection in the emergency spillway discharge channel. The swampy condition at the toe of the dam is not considered to be significant at this time; however, the condition should be monitored to document if seepage is developing.

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.

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.
