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 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 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 Gideon Yachin and published by . This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Lake Dam is located on Forest Lake Creek in Forest Lake Township, Susquehanna County, Pennsylvania. The original purpose of the impounded water was for ice harvesting and recreation. Additionally, water releases from the impoundment activated a saw mill. Presently, the lake is being used for recreation. The overall appearance of the dam is poor. Location of observed deficiencies are shown on the General Plan. The profile and typical sections of the dam are presented and are based on field survey made on the day of inspection. The survey datum for this inspection is elevation 1527 feet above mean sea level which is stamped on the USGS Bench Mark (No. TT15K, 1931) on the large sandstone slab, upstream of the service spillway. On the inspection date (12/10/1980), the lake was being drawn down for the winter. The lake level was approximately at elevation 1523.6, or 2.8 feet below its normal level. Deficiencies observed during the field inspection are described. Visible features are depicted in photographs.

Download or read book National Dam Inspection Program. Lewis Lake Dam (NDI-ID Number PA-00061, DER-ID Number 58-7), Susquehanna River Basin, Susquehanna County, Pennsylvania. Phase I Inspection Report written by Hendrik Jongsma and published by . This book was released on 1980 with total page 106 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 only 10 percent of the PMF peak inflow without overtopping the dam. The spillway is considered to be seriously inadequate. The dam is therefore unsafe, non-emergency.

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.

Arlington Brown, Susquehanna River Basin Tributary, West Branch Stony Fork Creek, Tioga County, Pennsylvania. Phase 1. Inspection Report written by and published by . 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.

Number 8-57) Susquehanna River Basin, Tributary to Fall Creek, Bradford County, Pennsylvania. Phase I Inspection Report written by Bernard M. Michalcin and published by . This book was released on 1980 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the facility is considered to be in good condition. The size classification of the facility is intermediate and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility is the PMF (Probable Maximum Flood). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 45 percent of the PMF prior to embankment overtopping. A breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided in the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency. Calculations also indicate that if the spillway were constructed in accordance with available desing drawings, the facility could pass and/or store approximately 63 percent of the PMF.

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 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction data indicate the Valley View Lake Dam is in poor condition. The deteriorated condition of the spillway walls, severe erosion of the spillway discharge channel, and seepage observed at the downstream toe are the primary deficiencies which cause concern for the safety of this facility. The dam in its present condition is considered to be unsafe, non-emergency. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass only 32% 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 Valley View Lake Dam is considered to be seriously inadequate. Measures recommended for immediate action are listed.

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 Albert Charles Hooke and published by . This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Lake Henry Dam is judged to be in good condition. The existing spillway can pass 60 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. If the embankments were raised 0.7 foot to their design elevation, the dam could pass the PMF with 0.05 foot of freeboard. The spillway capacity would then be rated as adequate. A low area between the two embankments acts as an auxiliary spillway. There is no stability analysis for the embankments. There is no evidence of significant problems threatening the embankments. The spillway weir is judged to be stable.
