This book was released on 1978 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, past performance, and available engineering data, the facility is considered in good condition. The spillway and reservoir are capable of passing and/or storing the flow resulting from a storm of PMF magnitude without overtopping; consequently, the spillway is considered adequate. It is recommended that the owner: (a) Fill in the erosion gullies that have developed to the right of the spillway sidewall with materials that will retard further erosion. The seepage should also be monitored to insure that the condition does not worsen, (b) Develop a formal warning system to notify downstream residents should hazardous conditions develop, and (c) Develop a manual for the operation and maintenance of the outlet works at the facility.

This book was released on 1981 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a review of available design information and visual observations of conditions as they existed on the date of the field inspection, the general condition of the Glade Run Dam is considered to be good. This assessment is based primarily on visual observations of the embankment and appurtenant structures. Glade Run Dam is an 'intermediate' size, 'high' hazard structure. Corps of Engineers guidelines recommend the Probable Maximum Flood (PMF) as the Spillway Design Flood for an 'intermediate' size, 'high' hazard dam. Glade Run Dam's Spillway Design Flood is the Probable Maximum Flood. Spillway capacity is 'inadequate' because the non-overtopping flood discharge was found, by using the HEC-1 computer program, to be 92 percent of the PMF. The visual inspection indicated several minor deficiencies. The deficiencies can be corrected or improved through implementation of the following recommended remedial and/or maintenance efforts.

Mihalcin and published by . This book was released on 1979 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in fair condition. Structural deficiencies noted during the inspection include an inoperable drawdown mechanism, seepage and ponded conditions at the downstream toe, dense overgrowth (bushes, weeds, small trees) on the down stream slope, and minor concrete deterioration in the spillway. The size classification of the facility is intermediate and its hazard classification is considered to be significant. In accordance with recommended guidelines, the Spillway Design Flood (SDF) for this facility is 1/2 the Probable Maximum Flood (PMF). Results of the hydrologic and hydraulic analysis indicate that the facility can accommodate approximately 32 percent of the PMF and/or 64 percent of SDF (1/2 PMF). Thus, the spillway system is considered inadequate, but not seriously inadequate.

Mihalcin and published by . This book was released on 1979 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, operational history, and available engineering data, the dam, despite being well maintained, is considered to be in poor condition. Observations made during the visual inspection suggest that the embankment may be structurally unsafe as extensive areas of seepage were noted on the downstream embankment slope and immediately below the toe area to the right of the outlet conduit. Seepage conditions became evident shortly after reservoir filling and have persisted in spite of the installation of a remedial sand drain system near the toe. Failure of the embankment does not appear imminent and the condition is presently considered non-emergency. It is recommended that the owner immediately develop and implement a warning system to notify downstream inhabitants should hazardous conditions develop. Included in the plan should be provisions for around-the-clock surveillance of the facility during periods of unusually heavy precipitation.

This book was released on 1979 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gallo Dam is a 29-foot high earth embankment approximately 690 feet long (including spillway). The embankment is reportedly comprised of 3 sections which include an impervious core, a semi-pervious upstream section and a pervious downstream section. The facility is served by a chute channel spillway, with discharges controlled by a free overfall, concrete weir structure. The spillway is located near the right abutment, and has a crest length of 39 feet. In addition, the facility is equipped with a 18-inch diameter steel pipe encased in concrete used as a low level outlet as well as a 16-inch diameter steel siphon which was installed in 1973.

This book was released on 1978 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the conditions as they existed on the dates of inspection (May 17 and 30, 1978), as revealed by the visual observations, and the review of available information, the condition of Indian Lake Dam is assessed to require immediate further investigation to determine its structural stability and appropriate measures for controlling seepage through the embankment. Field observations show that wet areas and slope irregularities exist on the downstream face of the dam, which suggests potential instability of the embankment. Various seepages on the left abutment also require further evaluation. The outlet pipe gate, which is the only emergency drawdown facility for the impoundment, is inoperative and should be repaired immmediately. Based on the recommended spillway evaluation procedure, the capacity of the spillway was found to be adequate to pass the recommended flow of probable maximum flood. It is recommended that the owner should develop a formal warning system to alert the downstream residents in the event of emergencies.

Anderson and published by . This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions on March 14 and April 16, 1979, the condition of Little Blue Run Dam is considered to be good. No conditions were noted at this time that would significantly affect the structural performance of the dam. The flood discharge facilities for the dam were designed to pass the probable maximum flood (PMF) without overtopping the embankment. Therefore, according to the recommended criteria, the flood discharge facilities of the dam are adequate. Presently, the pool elevation is approximately 170 feet below the dam crest level. The pool elevation is expected to reach spillway crest level in about the year 2010. The following recommendations should be implemented on a continuing basis: (1) The cracking observed on the crest should continue to be evaluated by the design engineers. Also, attention should be given to the slump and seepage observed on the left abutment. Erosion ditches on the right abutment should be filled; and (2) A formal warning system should be developed to alert the downstream residents in the event of emergencies.

This book was released on 1981 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Bigby Run 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 Bigby Run Dam appears to be in fair condition. Maintenance is considered fair. The concrete spillway is deteriorating with marked deterioration on the right spillway wall. Minor seepage was observed at the toe of the dam, adjacent to the left abutment contact. Seepage was estimated at 2 to 5 gallons per minute. The seepage should be monitored. The Bigby Run Dam is a high hazard-small size dam. The recommended Spillway Design Flood (SDF), for a dam of this size and classification, is in the range of 1/2 PMF to PMF. Since the Bigby Run Dam just meets the minimum criteria; and since the dam is located in a rural area suggesting only appreciable economic loss; compliance with the current practice of the Baltimore District Corps of Engineers leads to the selection of the 1/2 PMF as the Spillway Design Flood (SDF).

Dziubek and published by . This book was released on 1980 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Jo-Ann Dam, formerly known as Bracco Dam, is classified as a 'High' hazard - 'Small' size dam. The dam and reservoir, owned by Mr. Daniel Carapellucci, Sr., are used for recreational purposes. The dam was found to be in fair overall condition at the time of the inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will pass 27.5 percent of the Probable Maximum Flood (PMF) before overtopping of the dam occurs. A spillway design flood (SDF) in the range of the 1/2 Probable Maximum Flood (1/2 PMF) to the PMF is required for Lake Jo-Ann Dam. Because the dam is on the low end of the 'Small' size category, the 1/2 PMF was selected as the SDF. It was determined that during the 1/2 PMF the embankment would be overtopped by a maximum depth of 0.89 foot and a total duration of 5.00 hours. Because a limiting criteria of one foot or greater of overtopping and duration in excess of 2 hours was estimated for this dam, it was concluded that a dam failure during the 1/2 PMF is unlikely to occur.

Anderson and published by . This book was released on 1979 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The New Dam consists of an earth embankment approximately 330 feet long with a maximum height of 37 feet from the downstream toe and a crest width of 32 to 35 feet. The flood discharge facilities for the dam consist of a combined primary and emergency spillway located on the right abutment (looking downstream). The spillway is an earth channel excavated into the right abutment and includes neither an overflow control structure, nor an energy dissipation structure at the downstream end. The width of the channel varies from 30 feet at the upstream end to 20 feet at the downstream end. The channel follows the right abutment for approximately 200 feet, then turns left, and discharges freely over the hillside into the stream valley. The outlet works consist of a 24-inch cast-iron blowoff pipe and a concrete intake tower. The concrete intake tower is located on the upstream side of the dam approximately mid-height of the embankment. All the operating equipment on the intake tower has seriously deteriorated and is no longer functional. The blow-off pipe appears to extend 50 to 100 feet further upstream from the intake tower. No low-level intake structure was visible. Flow through the outlet conduit is controlled by a valve located at the downstream end. The valve was reportedly left open to draw down the lake.

Dziubek and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polk Dam is owned by the Polk State School and Hospital and is classified as a 'Significant' hazard - 'Small' size dam. The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will not pass the 100-year flood without overtopping the dam. A spillway design flood (SDF) in the range of the 100-year flood to the 1/2 Probable Maximum Flood (1/2 PMF) is required for Polk Dam. The 100-year flood was chosen as the SDF. During the 100-year flood, the dam is overtopped by a maximum of 0.61 foot for a duration of 1.50 hours. The spillway is therefore considered 'inadequate.' It is recommended that the owner immediately initiate an engineering study to further evaluate the spillway capacity and develop recommendations for remedial measures to reduce the overtopping potential of the dam. Several items of remedial work should be performed by the owner without delay.
