This book was released on 1980 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upper Aetna Lake Dam is a 32-year old earth roadway embankment approximately 230 feet long with a timber box spillway and bridge located about 60' from the west abutment. The embankment carries an asphalt paved two-lane road across the dam structure. The three-sided timber box spillway is affixed to the upstream face of the pile-supported one-span timber bridge and has a total crest length of 35.67 feet with one set of removable flashboards 3 feet 4 inches wide. Upper Aetna Lake Dam is assessed to be in a fair overall condition and is recommended to be downgraded to a significant hazard category. Overtopping would not exacerbate the danger to downstream property or human life and no detrimental findings were uncovered to question the structural stability. Remedial actions to be undertaken in the future consist only of regrading and seeding the minor erosion on the embankment sideslopes. The dam has an inadequate spillway capacity, being able to accommodate only 5% of the 100 year design flood. Further hydraulic studies are recommended.

This book was released on 1980 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Lower Aetna Lake Dam, initially listed as a high hazard potential structure, but reduced to a significant hazard potential structure as a result of this inspection, is judged to be in fair overall condition. The dam's spillways are considered inadequate because a flow equivalent to five percent of the One Hundred Year Flood would cause the dam to be overtopped. To ensure adequacy of the structure, the following actions, as a minimum are recommended: (a) The spillways' adequacy should be determined by a qualified professional consultant engaged by the owner using more sophisticated methods, procedures and studies within six months from the date of approval of this report. Within three months of the consultant's findings, remedial measures to ensure spillway adequacy should be initiated, and (b) Within six months from the date of approval of this report, the following remedial actions should be initiated: (1) Embankment areas behind the culvert wingwalls that have been eroded should be regraded and covered with slope protection, (2) Remove trees on the downstream embankment to lessen the piping potential, and (3) Divert water at the crest of the downstream slope to avoid gullying. Consideration should be given to constructing an extended asphalt lip curb along the rear edge of the pavement to control the run-off.

McDermott and published by . This book was released on 1981 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bethany Hole Dam is an earth embankment with primary and secondary spillways. In addition, a low area of the lake shore adjacent to the right end of dam serves as an auxiliary spillway. The primary spillway consists of a stoplog controlled drop inlet with discharges through a 48-inch CMP which transversely penetrates the dam embankment. The primary spillway also acts as the outlet works for the dam. The secondary spillway consists of a 36-inch CMP high level outlet which transversely penetrates the dam. Based on visual inspection, past operational performance and Phase I engineering analyses, the dam is assessed as being in fair overall condition. Hydraulic and hydrologic analyses indicate that the spillway is inadequate. Discharge capacity of the spillways is not sufficient to pass the designated spillway design flood (100-year storm) without an overtopping of the dam. The spillways, together with a low area in the lake shore adjacent to the dam, are capable of passing approximately 54 percent of the SDF.

McDermott and published by . This book was released on 1981 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report cites results of a technical investigation as to the dam's adequacy. The inspection and evaluation of the dam is as prescribed by the National Dam Inspection Act, Public Law 92-367. The technical investigation includes visual inspection, review of available design and construction records, and preliminary structural and hydraulic and hydrologic calculations, as applicable. An assessment of the dam's general condition is included in the report. Based on visual inspection, available records, calculations and past operational performance, Smithville Dam, a high hazard potential structure, is judged to be in fair overall condition. The dam's spillway is considered inadequate because a flow equivalent to 9 percent of the Spillway Design Flood - SDF- would cause the dam to be overtopped. (The SDF, in this instance, is one half of the Probable Maximum Flood). The decision to consider the spillway 'inadequate' instead of 'seriously inadequate' is based on the determination that dam failure resulting from overtopping would not significantly increase the hazard to loss of life downstream from the dam from that which would exist just before overtopping failure.

Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Crystal Lake Dam, initially listed as a high hazard potential structure, but reduced to a significant hazard potential structure as a result of this inspection is judged to be in good overall condition and the spillway is considered adequate. To ensure adequacy of the structure, several actions are recommended. The following actions should be initiated within six months from the date of approval of this report: (1) The outlet works should be investigated with respect to operational adequacy and, if necessary, restored to proper operational condition; (2) Rusted CMP surface drain pipe should be replaced by proper inlet and pipe; (3) Erosion of the embankment adjacent to the upstream wingwalls of the bridge should be properly stabilized; (4) Deteriorating riprap on the upstream and downstream faces of embankment should be repaired where necessary; and (5) All trees and adverse vegetation on the embankment should be removed.
