Flaherty and published by . This book was released on 1981 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Examination of available documents and a visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies that need to be evaluated and remedied. Hydrologic/hydraulic analyses performed in accordance with the Corps of Engineers' Recommended Guidelines for Safety Inspection of Dams indicate that the principal spillway and the emergency spillway would pass 100 percent of the outflow from the Probable Maximum Flood (PMF) without overtopping the dam. Therefore, the combined spillway capacity is adjudged to be adequate. (Author).

Flaherty and published by . This book was released on 1981 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Examination of available documents and a visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies that need to be evaluated and remedied. Using the Corps of Enginners' screening criteria for the initial review of spillway adequacy, it has been determined that the dam would be overtopped by all storms exceeding 29 percent of the Probable Maximum Flood (PMF) with the flashboards in place and 30 percent without them in place. Dam overtopping, the resulting instability of the overflow spillway and hence, dam breaching would cause water surface levels downstream to reach depths which would pose significant danger to residents. Therefore, the spillway is adjudged to be seriously inadequate and the dam is assessed as unsafe, nonemergency. The classification 'unsafe' applied to a dam because of a seriously inadequate spillway is not meant to connote the same degree of emergency as would be associated with an 'unsafe' classification applied for a structural deficiency. It does mean that there appears to be a serious deficiency in spillway capacity and if a severe storm were to occur, overtopping and failure of the dam could take place, significantly increasing the hazard to life downstream of the dam.

Flaherty and published by . This book was released on 1981 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of available documents and visual inspections of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies that need to be evaluated and remedied. The spillway is adjudged to be seriously inadequate and the dam is assessed as unsafe, nonemergency. It should be noted that Eaton Brook Reservoir Dam is located approximately 2.2 miles upstream of Clayton's Dam on Eaton Brook. Its spillway has also been adjudged to be seriously inadequate and the dam assessed as unsafe, nonemergency. Due to the appreciable size of Eaton Reservoir, the breaching of that dam would undoubtedly have a serious effect on Clayton's Dam. Similarly, the failure of either of these dams would have a serious effect on two small dams also on Eaton Brook, located 0.5 miles and 1.7 miles downstream of Clayton's Dam.

This book was released on 1981 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual inspection of this dam and engineering analyses revealed that the poor condition of the dam creates a hazard to human life and property. As a result of these determinations, the dam has been assessed as unsafe, non-emergency. One of the spillway sections has failed completely, creating a large void in the dam. The other spillway channel is in poor condition, having cracks in the concrete and several small voids. The earth fill upstream of the dam completely blocks the failed spillway section and partially blocks the other section. Due to the serious nature of the deficiencies, it is recommended that within 30 days of the notification to the owner that the dam has been assessed as unsafe, repair work on the structural deficiencies should be commenced. These repairs should be completed within 3 months. Within 3 months of the notification of the owner, a detailed hydrologic/hydraulic investigation should be commenced. This investigation should accurately define the site specific characteristics of the watershed and determine appropriate mitigating measures to be taken in response to the seriously inadequate spillway capacity. These measures should be completed within 1 year of the date of notification.

Flaherty and published by . This book was released on 1981 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little Choconut Watershed Site 2A Dam is one of eight floodwater retarding dams in the Little Choconut, Finch Hollow, and Trout Brook watersheds designed to reduce floodwater damages. The dam embankment is approximately 530 feet long, 33 feet high and has an upstream slope of 3 horizontal to 1 vertical and a downstream slope of 2.5 to 1. The principal spillway is a drop inlet structure consisting of a single stage reinforced concrete riser, a 24 inch diameter prestressed concrete cylinder pipe and a channel excavated into bedrock at the outlet of the conduit. The emergency spillway is a curved 80 foot wide channel with 3 to 1 side slopes cut into earth at the left abutment. Hydrologic/hydraulic analyses performed in accordance with the Corps of Engineers' Recommended Guidelines for Safety Inspection of Dams indicate that the principal spillway and the emergency spillway would pass 100 percent of the outflow from the Probable Maximum Flood (PMF) without overtopping the dam. Therefore, the combined spillway capacity is adjudged to be adequate.
