Phase I Inspection Report written by R. 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.

Number 40-16) Susquehanna River Basin, Branch of Kitchen Creek, Luzerne County, Pennsylvania. Phase I Inspection Report written by Bernard M. 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.

Phase I Inspection Report written by Bernard M. Mihalcin and published by . This book was released on 1980 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection, operational history, and hydrologic/hydraulic analysis indicate that the facility is in excellent 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 is capable of passing and/or storing the PMF. Consequently, its spillway is considered adequate. It is recommended that the owner immediately (a) provide positive drainage for the area between the left spillway wingwall and left abutment hillside and (b) repair and seal all concrete cracks observed along the left spillway wingwall. (Author).

Hathaway Pond Dam (NDI ID Number PA 00050, PennDER Number 58-06), Susquehanna River Basin, West Branch of Lackawanna River, Susquehanna County, Pennsylvania. Phase I Inspection Report written by John A. 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.

Phase I Inspection Report written by and published by . This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. 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.

Phase I Inspection Report written by R. 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.

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.

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 John A. Dziubek and published by . This book was released on 1981 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warner Dam is owned by William S. Newlin, Jr., and is classified as a 'Low' hazard - 'Small' size dam. The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations 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 50- year flood to the 100-year flood is required for Warner Dam. The 100-year flood was chosen as the SDF. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately develop remedial measures to provide adequate spillway capacity. The inspection revealed certain items of remedial work which should be performed by the owner without delay. These include: (1) Provide adequate spillway capacity; (2) Repair the spalling on the downstream face of the concrete corewall; (3) Ensure that the outlet works are operable, or develop an emergency drawdown plan; and (4) Cut all trees on the embankment at ground level. All trees with a trunk diameter greater than 3 inches should have their root systems removed. All resultant areas of erosion and cavities should be filled, graded, compacted and seeded. In addition, the following operational measures are recommended to be undertaken by the owner: (1) Develop a detailed emergency operation and warning system; (2) During periods of unusually heavy rainfall, provide around-the-clock surveillance of the dam; and (3) When warning of a storm of major proportions is given by the National Weather Service, activate the emergency operation and warning system.
