Phase I Inspection Report written by and published by . This book was released on 1981 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Marguerite 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. Marguerite Dam appears to be in fair condition and poorly maintained. The stability of the structure is questionable due to the steep downstream slope and the existance of seepage on the downstream slope adjacent to the right spillway wall (left abutment). The masonry wall located along the upstream face of the dam is collapsing in sections and falling into the reservoir. Cracking of the masonry wall at the right of the approach to the spillway is occurring, and should be repaired. Brush and small trees have been allowed to grow unchecked along the entire downstream slope of the dam. The entire area along the downstream toe of the dam is wet, and ponding is occuring in the area of the valve pit at the downstream toe. Positive drainage for the ponding should be provided. Seepage noted during the inspection was measured to range from 10 to 15 gallons per minute. The drainline valve is located at the downstream toe of the dam which is considered a deficiency.

Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1979 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the conditions existing April 9 and May 25, 1979, the condition of Mammoth Lake Dam is considered to be good. The only two conditions noted which would require attention at this time are the filling of the erosion ditches on each side of the spillway structure and cleaning the debris from the outlet works discharge structure. The flood discharge capacity of Mammoth Lake Dam was found to be within the recommended capacity range of the 100-year flood to one-half of the probable maximum flood (PMF) relative to its size and hazard classification. Considering the 15-foot height of the dam is within the middle one-third of the zero to 25-foot height size classification range, the spillway capacity of 4770 cfs is rated to be adequate.

Phase I Inspection Report written by GAI CONSULTANTS INC MONROEVILLE PA. and published by . This book was released on 1979 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upper Bridgeport Dam is an earth embankment approximately 1,020 feet long (including spillways), with a maximum height of 21 feet. The embankment is divided into three sections by two spillways. The service spillway is a combination masonry and concrete trapezoidal-shaped weir structure with a 101-foot long crest located about 140 feet from the left abutment. The emergency spillway is a concrete broad-crested weir structure with a 250-foot crest length located about 320 feet to the left of the right abutment. Based on the visual inspection, operational history, and available engineering data, the dam is considered to be in poor condition. The facility has been essentially abandoned by the current owner and has not been in operation or maintained since 1972. Results of the hydrologic and hydraulic analysis indicate that the facility can accommodate approximately 20 percent of the PMF before overtopping of the embankment occurs. Since the dam's hazard rating is high, and embankment failure would result in an increase in the potential for loss of life downstrean from the dam, the present spillway system is assessed as being seriously inadequate.

Phase I Inspection Report written by Bernard M. Mihalcin and published by . This book was released on 1979 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, past performance, and available engineering data, the facility is considered to be in good condition. The size classification of the facility is intermediate and the hazard classification is considered to be high. The emergency spillway is capable of discharging the peak inflow resulting from a storm of PMF intensity and is, therefore, considered adequate. It is recommended that the owner: (a) Repair the damaged pond drain gate control and replace the missing manhole cover atop the service spillway riser. Consideration should be given to redesigning the gate control mechanism to protect it from future vandalism. (b) Consult with the U.S.D.A., Soil Conservation Service, to assess the erosion on the upstream slope in the area of the service spillway riser and implement any remedial measures deemed necessary. (c) Curtail the unauthorized vehicular travel across the embankment and repair and reseed any damaged (bare) areas. If control of unauthorized travel is not practical, some provision should be made to protect the embankment from rutting and erosion by placing a layer of gravel or stone across the crest. (d) Develop a formal operation and maintenance manual to ensure the continued proper care of the facility. In addition, a formal warning system should be implemented which provides detailed procedures to protect the lives and property of downstream residents. Included in the plan should be provisions for around-the-clock surveillance of the facility during periods of unusually heavy percipitation.

Phase I Inspection Report written by GAI CONSULTANTS INC MONROEVILLE PA. and published by . This book was released on 1979 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jeannette Dam is a 36-foot high earth dam approximately 480 feet in length. The dam impounds a small 10-acre reservoir locally known as Mountain Valley Lake. The facility is equipped with a small concrete and masonry spillway located approximately 35 feet upstream of the embankment along the western shore of the lake. The spillway discharges into a trapezoidal-shaped diversion channel which parallels the western shore. A historical report indicates that the diversion channel, approximately 1500 feet in length, was designed to divert all stream inflow completely around the reservoir and that water was piped to the reservoir from other impoundments. Jeannette Dam is located across a small branch of Brush Creek approximately 2.5 miles west of Greensburg, in Hempfield Township, Westmoreland County, Pennsylvania.

Book excerpt: The visual inspection, operational history, and hydrologic/hydraulic analysis indicate the facility is in good condition. It is recommended that the owner: (a) Immediately fill and seal all cracks within the interior of the outlet conduit. (b) Specifically address the seepage condition observed to the right of the spillway in all future inspections and note any turbidity or changes in the rate of flow. (c) Re-evaluate and revise the present standard flood emergency procedures in accordance with, but not limited to, the following items: (1) Include a definite procedure of notifying downstream residents of a possible emergency. (2) Provide for an alternate means of communication in the event telephone lines become inoperative. (3) Provide for around-the-clock surveillance of the facility during periods of unusually heavy precipitation. (d) Provide additional riprap protection along the right sidewall of the spillway approach channel.

Kenda Dam (NDI Number PA 00459, PennDER Number 65-118), Ohio River Basin, Tributary of Little Sewickley Creek, Westmoreland County, Pennsylvania. Phase I Inspection Report written by John A. Dziubek and published by . This book was released on 1980 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kenda Dam is owned and operated by the Westmoreland Recreation Society, Inc. and is classified as a Small size - High hazard dam. The dam was found to be in poor 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 1/2 Probable Maximum Flood (1/2 PMF) without overtopping the dam. A spillway design flood (SDF) in the range of the 1/2 PMF to Probable Maximum Flood (PMF) is required for Kenda Dam. The 1/2 PMF was selected as the SDF because of the small size of the drainage area and impoundment. During the 1/2 PMF, the dam is overtopped by a maximum depth of 1.24 feet for a total duration of 7.00 hours. It is estimated that, in its present condition, the dam is likely to fail during the 1/2 PMF. Analysis performed to assess the impact of failure of the dam on the damage center downstream indicated that a significant increase in damage would occur compared to conditions if the dam did not fail. Therefore, the spillway is assessed as being seriously 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.

Book excerpt: The PA-482 dam is one of the 14 flood control projects in the Harmon Creek watershed. The dam consists of an earth embankment approximately 460 feet long with a maximum height of 38 feet from the downstream toe and a crest width of 14 feet. The flood discharge facilities for the dam consist of a drop inlet primary spillway located at the center of the embankment and an emergency spillway on the left abutment (looking downstream). The primary spillway structures consist of a two-stage reinforced concrete riser, a 24-inch-diameter reinforced concrete conduit, and a reinforced concrete impact basin at the downstream end of the outlet pipe. The emergency spillway is a 200-foot-wide trapezoidal earth channel excavated into the left abutment. The reservoir outlet for the dam consists of a 15-inch steel pipe extending from the upstream toe of the dam to the drop inlet structure. Flow through the reservoir outlet is controlled by a manually operated sluice gate lcoated in the drop inlet structure.

Phase I Inspection Report written by GAI CONSULTANTS INC MONROEVILLE PA. and published by . This book was released on 1979 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beaver Dam is an earth embankment approximately 32 feet high and 385 feet long (including spillway). The dam is constructed with a masonry spillway located about 35 feet left of the right abutment. The crest of the spillway is 100 feet long and about 11 feet below the top of its wingwalls. Based on a visual inspection, operational history, and available engineering data, the dam is consisered to be in poor condition. The defunct facility has been essentially abandoned since 1952 and its reservoir is sediment filled. Results of the hydrologic and hydraulic analysis indicate that the facility is capable of passing and/or storing only 36 percent of the PMF without embankment overtopping. Structural deficiencies noted by the inspection team included substantial embankment overgrowth, an access road cut through the embankment near the left abutment, cracking of the masonry spillway wingwalls, and a sediment filled reservoir. Due to the seriously inadequate spillway and overall poor condition, the facility is considered unsafe but non-emergency as failure is not considered imminent.

Phase I Inspection Report written by John A. Dziubek and published by . This book was released on 1980 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ligonier Dam (Ligonier Township Reservoir) is classified as a 'High' hazard - 'Small' size dam. The dam and reservoir, owned by the Ligonier Township Municipal Water Authority, are used for water supply. The dam was found to be in good 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 pass approximately 35 percent of the Probable Maximum Flood (PMF) before overtopping will occur. A spillway design flood (SDF) in the range of the 1/2 Probable Maximum Flood (1/2 PMF) to the PMF is required for Ligonier Dam. Because of the relative small size of the impoundment the 1/2 PMF was chosen as the SDF. It was determined that during the 1/2 PMF the low area on the embankment would be overtopped by a depth of 0.66 foot and a duration of 4.50 hours. Because a limiting criteria of one foot or greater depth of overtopping and a duration of 2 hours was estimated for this dam, it was concluded that a dam failure during the 1/2 PMF is unlikely to occur.
