Book excerpt: Galvin Pond Dam is owned by Mr. Walter Kirby 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 evaluation, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, revealed that the spillway capacity is less than the peak inflow to the impoundment during the 100-year flood. 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 Galvin Pond Dam. Because the dam is on the low end of the 'Small' size category in terms of storage capacity and height, the 100-year flood was chosen as the SDF. The spillway is therefore considered 'Inadequate.' Several items of remedial work should be immediately initiated by the owner. These include: (1) Develop remedial measures to ensure that the dam is not overtopped by the 100-year flood; (2) Repair the two 12-inch steel pipes, fill the embankment to original crest elevation and reseed with grass; (3) Cut the trees and brush on the dam; and (4) Provide means to draw down the reservoir during an emergency.

Jeffrey Kimball and published by . This book was released on 1981 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is located approximately 2 miles northwest of the Village of Colley, Wilmot Township, Bradford County, Pennsylvania. The inspection consisted of: Visual inspection of the retaining structure, abutments and toe; Examination of the spillway facilities, exposed portion of any outlet works and other appurtenant works; Observations affecting the runoff potential of the drainage basin; and Evaluation of the downstream area hazard potential. The dam appears to be in good condition and adequately maintained. From a brief survey conducted during the inspection, it was noted that the low spot on the crest of the dam exits at the top left edge of the spillway crest. It was observed during the inspection that a new concrete cap had been placed on the structure. The concrete appeared to be in good condition. The dam was constructed with dry rubble masonry with an upstream earthfill. No concrete exists on the downstream face of the structure or on the bench located along the downstream face of the structure. The rubble masonry appeared to be in good condition and well maintained.

Dziubek and published by . This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hathaway Pond Dam is located in Ararat Township, Susquehanna County, Pennsylvania. The reservoir was originally created to provide water for power purposes. The reservoir slopes are moderate with a good cover of vegetation. There are three ponds upstream from Hathaway Pond Dam on two tributary streams. The western stream contains Romobe Lake (PennDER I.D. No. 58-10) which is 1750 feet upstream from Hathaway Pond Dam. The eastern tributary contains Ball Lake and an unnamed smaller pond in series. Ball Lake is 2450 feet upstream and will retain considerable storage while the smaller unnamed pond was considered to have no effect on Hathaway Pond Dam. Two homes, a trailer, and township road are located 1800 feet downstream from Hathaway Pond Dam. These could suffer economic damage in the event of a dam failure.

This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Cooks Pond Dam is considered to be unsafe/nonemergency due to the seriously inadequate spillway capacity and structural deficiencies. The condition of the embankment is considered to be poor. The dam is old and in a general state of disrepair. The crest of the dam is irregular and the center of the dam appears to have settled. The stone wall along the downstream toe is irregular and bulging. The toe of the wall is swampy, caused by a general underseepage. In view of these observations, the overall stability of the dam is considered to be questionable, requiring further investigation and implementation of measures to improve the stability of the dam. The spillway capacity was evaluated according to the recommended procedure and was found to pass less than 10 percent of the Probable Maximum Flood (PMF) without overtopping the embankment. This capacity is less than the required spillway capacity of one-half PMF relative to the size and hazard classification of the dam. Because the spillway capacity is less than 50 percent of the PMF and it is estimated that failure of the dam due to overtopping would significantly increase the downstream hazard of loss of life compared to that which would exist just before failure, the spillway is considered to be seriously inadequate, and consequently the condition of the dam is considered to be unsafe/nonemergency.

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.

Jeffrey Kimball and published by . This book was released on 1981 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pomeroy Memorial Reservoir Dam appears to be in poor condition and poorly maintained. The concrete on the upstream slope of the dam is in a deteriorated condition as is the concrete in the spillway section. The spillway retaining walls are visibly deteriorated and a section of the right spillway wingwall has cracked and fallen away from the structure. Maintenance of the dam and operating facilities is considered poor. The drainline valves have not been operated in the recent past. Pomeroy Memorial Reservoir 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. Based on the downstream potential for loss of life, the spillway design flood has been selected as the PMF. The spillway and reservoir are capable of controlling approximately 9% of the PMF without overtopping the embankment low spot. If the low spot elevation were to be filled to an elevation consistent with the remaining portion of the embankment crest the spillway and reservoir would be capable of controlling approximately 20% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed inadequate.

Jeffrey Kimball and published by . This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Sugar 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 inspection and review of Sugar Creek Dam did not reveal any problems which would require emergency action. The dam appears to be in fair condition and in need of minor maintenance. The Sugar Creek 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 PMF. The PMF has been selected as the spillway design flood based on the downstream potential for loss of life. The spillway and reservoir are considered capable of controlling approximately 50% of the PMF. The 0.1 feet of overtopping of the embankment crest during the 1/2 PMF event for a duration of 1 hour was not considered sufficient to cause failure of the structure. Based on the judgement of the evaluating engineer, the location and duration of the overtopping as well as the existence of a concrete curb on the upstream and downstream edge of the embankment crest would sufficiently contain the overtopping to the spillway area minimizing damage to the embankment and spillway. The spillway is considered inadequate.

Mihalcin and published by . This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harris Pond Dam is a combination earth, concrete and masonry structure approximately 10 feet high and 135 feet long, including spillway. It is located on Roaring Brook Creek in Ross Township, Luzerne County, Pennsylvania. The overall appearance of the facility suggests it to be in good condition. The only deficiency noted by the inspection team that requires immediate remedial attention was the areas exhibiting concrete deterioration. Flashboards (reportedly removed during significant storms) were observed in-place across the service spillway. Although generally considered undesirable, they appear, in this particular case, to be of little significance relative to the safe operation of Harris Pond Dam.

Dziubek and published by . This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Miller's Pond Dam is owned by Ernest Weaver and is classified as a 'Low' hazard - 'Small' size dam. The dam was found to be in poor overall condition at the time of inspection. Hydraulic/hydrologic evaluations revealed that the spillway will pass the 100-year flood without overtopping the dam. A spillway design flood (SDF) in the range of the 50-year flood to the 100-year flood is required for Miller's Pond Dam. The 100-year flood was chosen as the SDF. Therefore, the spillway is considered 'Adequate'. There are two seeps, approximately 5 g.p.m. and 1 g.p.m., and a minor boil near the downstream toe of the dam. There are depressions along the upstream crest which may indicate 'piping' of the embankment materials. These ares should be monitored. Several items of remedial work should be immediately initiated by the owner. These include: (1) Monitor the two areas of seepage at regular intervals and during periods of high reservoir levels for turbidity and/or increase in flow, which may indicate the potential for piping of embankment material. If turbidity or increased flows are noted, a qualified geotechnical engineering firm should be retained to recommend remedial measures. (2) Fill, compact, and seed the depressions on the crest of the dam. (3) Cut all trees and brush on the embankment at ground level. (4) Clear the spillway approach channel of all debris and protect with riprap. (5) Repair the discharge apron and training walls. (6) Fill and seed the areas of erosion behind the wingwalls. (7) Protect the channel immediately downstream from the embankment with erosion protection. (8) Provide means to draw down the reservoir during an emergency.

Mihalcin and published by . This book was released on 1980 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Jean Dam is a zoned earth embankment approximately 26 feet high and 780 long, including spillway. The emergency spillway is an uncontrolled, rectangular, concrete and rock cut chute channel located at the right abutment. The crest of the spillway is 20 feet long and is spanned by a concrete bridge which supports a portion of the bituminous roadway that covers the embankment crest. Drawdown capability is provided by means of a 30-inch diameter cast iron blowoff pipe controlled at the inlet by a 30-inch diameter sluice gate. The facility consists of a main dam (Lake Jean Dam) and two appurtenant saddle dams (east and west dikes). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store about 73 percent of the PMF prior to overtopping the east dike. Thus, based on the screening criteria contained in the recommended guidelines, the spillway is considered to be inadequate, but not seriously inadequate. Should the saddle dams be regraded to their design elevation, the spillway would then pass floods in excess of the PMF and would be considered adequate.

This book was released on 1981 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beaver Pond Dam is classified as a 'Significant' hazard - 'Small' size 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 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 Beaver Pond Dam. Because the dam is on the low end of the 'Small' size category in terms of storage capacity and height, the 100-year flood was chosen as the SDF. During the 100-year flood, the dam is overtopping by a maximum depth of 3.27 feet for a total duration of 8.67 hours. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately develop recommendations for remedial measures to reduce the overtopping potential of the dam.
