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.

Download or read book National Dam Inspection Program Chambers Dam NDI ID Number PA 1093 DER ID Number 63 21 Ohio River Basin Bane Creek Washington County Pennsylvania Phase I Inspection Report written by KIMBALL (L ROBERT) AND ASSOCIATES EBENSBURG PA. and published by . This book was released on 1981 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chambers Dam appears to be in poor condition and poorly maintained. Erosion of the upstream slope has reduced the embankment crest to a width of 4 feet. Minor seepage was observed on the downstream slope of the dam, and a wet area was observed immediately beyond the toe of the dam. Brush and trees litter the downstream slope of the dam. No determination could be made as to the actual condition of the drainline culvert through the embankment. No determination could be made as to the condition or type of upstream closure on the culvert or whether the control is operable. The spillway located at the right abutment of the dam is in a deteriorating condition. Erosion exists along the right outside edge of the spillway wingwall. If the erosion is left unchecked, the potential for failure of the spillway and dam exists. The Chambers 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 and property damage, the spillway design flood has been selected as the PMF. The spillway and reservoir are capable of controlling less than 1% of the PMF without overtopping the embankment low spot.

This book was released on 1980 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, Brookville Water Works Dam was found to be in good condition and adequately maintained. The flood discharge capacity of the dam was evaluated according to the recommended procedure and was found to pass less than the 100-year flood without overtopping the embankment portion of the dam. The recommended spillway capacity range is between the 100-year flood and 50 percent of the probable maximum flood (PMF). Considering the low downstream damage potential, the lower limit of the recommended spillway capacity range was considered to be applicable to this dam. Therefore, the flood discharge capacity is classified to be inadequate. However, considering that the slopes of the earth embankment are protected with riprap and the dam has a concrete core wall, and further that the dam has withstood overtoppings in the past without breaching, overtopping of the earth embankment during the passage of 100-year flood can be permitted. Therefore, enlargement of the spillway is not considered to be justified. (Author).

Mihalcin and published by . This book was released on 1981 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and hydrologic/hydraulic analysis, the dam is considered to be in good condition. The size classification of the facility is small and the hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Since the facility is classified near the lower bounds of the small category, the SDF is considered to be the 1/2 PMF. Results of hydrologic and hydraulic analyses indicate the facility will pass and/or store approximately 40 percent of the PMF prior to embankment overtopping at the low area in the embankment crest (elevation 1177.4). 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 by the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency. Recommendations for owner action are listed.
