Walsh and published by . This book was released on 1981 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thelma Pitts Dam is an earthfill embankment approximately 18.6 feet high and 250 feet long. The principal spillway is a concrete drop inlet riser located near the left abutment. An emergency spillway is located on each abutment. The dam, located about 0.9 miles west of Sparta, Virginia, is used for recreation. Thelma Pitts Dam is a 'small' size - 'significant' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures were in good overall condition at the time of inspection. Maintenance of the dam is considered to be inadequate. A stability check of the dam is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 100-year flood was selected as the spillway design flood (SDF). The spillway is capable of passing up to 45 percent of the SDF or 8 percent of the Probable Maximum Flood (PMF) without overtopping the non-overflow section of the dam. The spillway is adjudged as inadequate but not seriously inadequate.

Phase I Inspection Report written by James A. Walsh and published by . This book was released on 1981 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Heritage Dam is an earthfill embankment approximately 19.8 feet high and 1,310 feet long with a 29.9 foot wide by 4 foot high concrete weir spillway situated about 40 feet from the right abutment of the dam. The dam, located about 2.5 miles west of Ladysmith, Virginia, is used for recreation. The dam is owned by the Lake Land' or Property Owner's Association, Box 123, Ladysmith, Virginia 22501. Lake Heritage Dam is a 'small' size - 'high' hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures were in fair overall condition at the time of inspection. Maintenance of the dam is considered to be inadequate. A stability check of the dam is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 1/2 Probable Maximum Flood (1/2 PMF) was selected as the spillway design flood (SDF). The SDF was routed through the reservoir and found to overtop the dam by a maximum depth of 0.7 feet with an average critical velocity of 3.8 feet per second. Total duration of overtopping would be approximately 1.9 hours.

Phase I Inspection Report written by James A. Walsh and published by . This book was released on 1981 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Land' or Dam is an earthfill dam with an embankment approximately 2,159 feet long and 28.2 feet high, and a 39.9 foot long concrete spillway. The dam, located in Caroline County, Virginia, is used to impound Lake Land' or for recreational purposes by the residents of the Lake Land' or Development Community. Lake Land' or Dam is an 'intermediate' size - 'significant' hazard dam as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures appear to be in fair overall condition. Visual inspection of the dam revealed several minor deficiencies requiring further attention. A stability check of the dam is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 1/2 Probable Maximum Flood (1/2 PMF) was selected as the spillway design flood (SDF). The SDF was routed through the reservoir and found to reach a maximum water surface elevation 1.3 feet above the top of the dam. The spillway is capable of passing up to 25 percent of the Probable Maximum Flood or 50 percent of the SDF without overtopping the crest of the dam. Therefore, the spillway has been adjudged as inadequate, but not seriously inadequate since there is not a high hazard to loss of life downstream of the dam from large flows.

Walsh and published by . This book was released on 1981 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beatties Millpond Dam is an earthfill embankment approximately 13.9 feet high and 365 feet long with a 32 foot wide broad-crested concrete weir spillway located at the left abutment. The dam, located about 2.3 miles northeast of Old Cold Harbor, Virginia, is used for recreation. Beatties Millpond Dam is a small size - significant hazard structure as defined by the Recommended Guidelines for Safety Inspection of Dams. The dam and appurtenant structures were in good overall condition at the time of inspection. Maintenance of the dam is considered to be inadequate. A stability check of the dam is not required. Using the Corps of Engineers' screening criteria for initial review of spillway adequacy, the 100-year flood was selected as the spillway design flood (SDF). The spillway is capable of passing up to 40 percent of the SDF or 8 percent of the PMF without overtopping the dam. A dam failure from overtopping would not significantly increase the hazard to loss of life downstream from the dam over that which would exist just before overtopping failure. However, overtopping flows from the SDF are considered detrimental to the earth embankment. Therefore, the spillway is adjudged as inadequate but not seriously inadequate.

Taran and published by . This book was released on 1981 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is an earthfill structure about 800 feet long and 45.2 feet high. The dam is classified as an intermediate size dam with a significant hazard classification. The designed principal spillway is a 10-inch steel drop-inlet stand pipe located in the reservoir. Because of underlying cavernous limestone beneath the reservoir, the water level is considerably below the normal design pool. There are two emergency spillways. The left emergency spillway is an open channel spillway which is a low point in natural ground. The right emergency spillway is an open channel cut into natural ground. The spillways will pass the PMF without overtopping; therefore, the spillways are adjudged as adequate. The visual inspection revealed no apparent problems or remedial measures in need of immediate attention.

Phase I Inspection Report written by michael Baker (III.) and published by . This book was released on 1979 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pursuant to Public Law 92-367, Phase I Inspection Reports are prepared under guidance contained in the recommended guidelines for safety inspection of dams, published by the Office of Chief of Engineers, Washington, D.C. 20314. The purpose of a Phase I investigation is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general conditions of the dam is based upon available data and visual inspections. Detailed investigation and analyses involving topographic mapping, subsurface investigations, testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify any need for such studies. Phase I reports include project information of the dam and appurtenances, all existing engineering data, operational procedures, hydraulic/hydrologic data of the watershed, dam stability, visual inspection report and an assessment including required remedial measures.

Phase I Inspection Report written by Michael Baker (III.) and published by . This book was released on 1981 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of a Phase I Inspection is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general conditions of the dam is based upon available data and visual inspection. Detailed investigation and analyses involving topographic mapping, subsurface investigations, testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the investigation is intended to identify any need for such studies. Based upon the field conditions at the time of the field inspection and all available engineering data, the Phase I report addresses the hydraulic, hydrologic, geologic, geotechnic, and structural aspects of the dam. The engineering techniques employed give a reasonably accurate assessment of the conditions of the dam. It should be realized that certain engineering aspects cannot be fully analyzed during a Phase I inspection. Assessment and remedial measures in the report include the requirements of additional indepth study when necessary. Phase I reports include project information of the dam appurtenances, all existing engineering data, operational procedures, hydraulic/hydrologic data of the watershed, dam stability, visual inspection report and an assessment including required remedial measures.
