This book was released on 1981 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of existing conditions, the condition of Rossiter Dam is considered to be unsafe/nonemergency due to a seriously inadequate spillway capacity. The overall condition of the dam is considered to be poor. The spillway structures have partially collapsed and the dam is overgrown with large trees and thick brush, precluding a complete inspection. The spillway capacity was evaluated according to the recommended criteria and was found to be seriously inadequate. According to the recommended criteria, small dams in the high hazard category are required to pass from one-half to full Probable Maximum Flood (PMF). In view of the small size of the dam, one- half of the PMF was selected as the spillway design flood. Flood discharge capacity was evaluated according to the recommended procedure and was found to pass 20 percent of the PMF without overtopping the embankment. Since the spillway capacity is less than 50 percent of the PMF and results of a breach analysis indicate that the potential loss of life and downstream damage would be significantly increased due to a dam failure, the spillway is classified to be seriously inadequate.

Mihalcin and published by . This book was released on 1980 with total page 82 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 good condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2-PMF (Probable Maximum Flood) and the PMF. Due to the relatively small storage capacity and the unusually stable embankment configuration the SDF for the facility is considered to be the 1/2-PMF. Results of the hydrologic and hydraulic analysis indicate the facility is capable of passing and/or storing a flood of 1/2-PMF magnitude. Consequently, the spillway is considered adequate. It is recommended that the owner: (a) Develop a formal emergency warning system to notify downstream residents 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. (b) Observe the cracking in the spillway overflow wall and outlet conduit headwall in future inspections and take remedial measures if necessary. (c) Develop formal manuals of operation and maintenance to ensure the continued proper care of the facility.

Andersen and published by . This book was released on 1980 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sample Run Dam consists of an earth embankment approximately 325 feet long with a maximum height of approximately 23 feet from the downstream toe. The crest width is approximately 10 feet. As designed, the downstream face of the dam was to be protected by grass, and a vertical concrete wall on the upstream side was to provide shoreline protection. Presently, the downstream face of the dam is covered with brush and trees up to 10 feet high and the concrete wall on the upstream side has partially collapsed. The spillway structures are comprised of an 18-foot-wide concrete ogee overflow section which discharges into an 18-foot-long concrete channel, incorporating an energy dissipator sill. Based on the evaluation of the existing conditions, the condition of Sample Run Dam is considered to be poor. The dam is abandoned and is in complete disrepair. A valve house located at the downstream toe of the dam has collapsed, covering most of the operating equipment with rubble. The flood discharge capacity of the dam was evaluated according to the recommended procedure and was found to pass 20 percent of the probable maximum flood (PMF).

Anderson and published by . This book was released on 1979 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the conditions of Musser Forests Dam, the dam is considered to be unsafe due to severe erosion in the primary spillway and emergency discharge channel along the toe of the dam near the left abutment and due to the lack of an operable outlet works for the reservoir. However, it is not considered to be an emergency condition. Field observations indicate that the crest of the dam is irregular with elevations ranging from 1.7 to 5.9 feet above the emergency spillway crest level. The irregularities do not appear to be due to recent movements. The upstream slope of the dam has no erosion protection and has been partially eroded by wave action. The emergency spillway approach channel is overgrown with tall grass and cattails which may constitute a partial obstruction to flow through the spillway. The flood discharge capacity of Musser Forests Dam was evaluated and found to pass 30% of the probable maximum flood (PMF) without overtopping the low spot on the crest of the dam. Therefore, according to the recommended criteria, the flood discharge capacity of Musser Forests Dam is classified to be inadequate.

This book was released on 1981 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pond No. 4 Dam is classified as a 'small' size, 'significant' hazard dam, with a recommended 1/2 PMF (Probable Maximum Flood) spillway design flood. Based on the review and evaluation of available design information and visual observations of conditions as they existed on the dates of the field reconnaissances, the general condition of Pond No. 4 Dam is assessed poor. This evaluation is specifically based on a steep upstream embankment slope, sparse vegetation cover on the crest and upstream slope, and minor slope distress and tree and woody shrub growth on the downstream embankment. Seeps located along the downstream embankment toe also represent a potential hazard and warrant periodic observation by the dam owner. In addition, the unprotected spillway channel bottom and sideslopes may also present hazard to the dam during large spillway discharges. Analysis using the HEC-1 Dam Safety version computer program indicated the spillway channel section can pass the recommended 1/2 PMF spillway design flood without overtopping the embankment crest. Spillway discharge capacity is therefore considered adequate. (Author).

This book was released on 1981 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Saxony Dam is located across Sarver Run, in Jefferson Township, Butler County, Pennsylvania. The dam is approximately one mile east of Saxonburg, Pennsylvania. Lake Saxony Dam is classified as a 'high' hazard dam. In the event of a dam failure, at least nine inhabited dwellings on the floodplain below the dam would be subjected to possible damage and loss of more than a few lives could result. The field inspection of Lake Saxony Dam was performed on 2 December 1980, and consisted of: Visual observations of the embankment crest and slopes, groins and abutments; Visual observations of the principal and emergency spillways including intake structures, outlet structures, and approach and discharge channels; Visual observations of the embankment's downstream toe area including drainage channels and surficial conditions; Transit stadia field measurements of relative elevations along the embankment crest centerline, spillway, and across the embankment slopes; Visual observations of the reservoir shoreline and watershed; Visual observations of downstream conditions and evaluation of the downstream hazard potential. The visual observations and measurements were made during periods when the reservoir and tailwater were at normal operating levels.

This book was released on 1978 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periodic state inspection reports reveal the dam has been adequately maintained over the years. In fact, the majority of these reports state its general appearance to be good. The inspection reports, however, clearly document what appeared to be a steadily deteriorating condition relative to the concrete. Leaks at various locations along the spillway have also been ovbserved but apparently were never considered significant. In addition, minor settlement of the embankment crest near the spillway was also mentioned. Records indicate that consideration was given to the construction of a new facility around 1960. Subsurface investigations of the dam site and proposed borrow areas were performed, but construction was not undertaken. Thus the facility in existence today is virtually the same one constructed in 1903.

Mihalcin and published by . This book was released on 1979 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cherry Run Dam is a zoned earth embankment with a central concrete corewall. The embankment measures approximately 430 feet long (including spillway) and 22 feet high. The facility is provided with an ogee-shaped concrete spillway located about 100 feet from the right abutment. The spillway crest is 132 feet long. Based on a visual inspection, maintenance of Cherry Run Dam appears minimal to non-existent and the facility is considered to be in poor condition. Deficiencies noted by the inspection team included heavy overgrowth of the embankment sections (particularly to the right of the spillway), delamination of the spillway surface, cracking and misalignment of the spillway wingwalls, heavy overgrowth within the discharge channel, an inoperable outlet works, and no emergency warning systems in effect. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only 40 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.
