Bluhm and published by . This book was released on 1981 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lambert Dam is a linear earthfill structure 605 feet long and 53 feet high with a crest width of 18 feet. The upstream and downstream slopes are IV on 3.8H and IV on 3.4H respectively. It has a capacity of 336 acre-feet at normal pool and 454 acre-feet at the top of the dam. The dam is in the intermediate size and high potential category and should pass the Probable Maximum Flood (PMF). A hydraulic and hydrologic analysis reveals that during the PMF the dam will overtop by 1.3 feet for 4.75 hours. During the 1/2 PMF, the dam overtops by .65 feet for three hours. The embankment appears to be structurally stable; however, it is considered significantly deficient because the spillway is inadequate. It is recommended that a qualified engineer be engaged to develop project modifications that will allow the dam to pass the PMF and that the owner perform routine maintenance operations.

Wedekind and published by . This book was released on 1981 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kagley Dam intercepts an unnamed tributary of Sixmile Creek about one mile south of the Mint Community in Blount County. The crest of the 27.6 foot high earth-filled embankment is 12 feet wide and 168 feet long. Means of discharge from the reservoir include a riser with a 6 inch outlet and a parabolic open channel spillway in the right abutment. The embankment slopes, greater than 1V:3H, do not appear to be steep and there is no evidence of slides or other signs of instability. A soft area on the downstream face near the middle of the embankment does not appear to threaten the safety of the dam. A break in the service spillway outlet pipe near the toe allowed erosion of the embankment to form a 4 foot diameter hole over the break. Although this break does not jeopardize the integrity of the embankment, the possibility of other breaks due to embankment settlement poses a threat to the safety of the dam. Kagley Dam is classified in the small size and high hazard potential categories and therefore is required to pass a design storm of between the half and full probable maximum flood (PMF). Hydraulic analysis reveals the spillway to be seriously inadequate due to the inability to pass the 100 year storm which overtops the dam by a maximum depth of 0.18 feet for a duration of 2.57 hours. The dam is overtopped by the 1/2 PMF by a maximum depth of 1.8 feet for a duration of 5.66 hours.

Bush and published by . This book was released on 1981 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grand Valley Dam No. 2 is located in Hardeman County, Tennessee seven miles east of Hickory Valley, Tennessee and is an earth fill embankment 16 feet high and 560 feet long with a crest width of 22 feet. Facilities for discharge for the reservoir are located in the left abutment and include a 24 inch corrugated metal pipe culvert through the dam, and an emergency spillway cut into the right abutment. This spillway is trapezoidal shaped with a bottom width of 50 feet. A paved road fill crosses the spillway at approximately the location of the control section and effectively cuts off the spillway from use. The embankment slopes are 1 vertical on 3 horizontal from the water line to the top of the dam on the upstream slope. The downstream slope averages 1 vertical on 3 horizontal. The upstream slope is free of undesirable growth and debris but the downstream slope is covered with high grass and small saplings. On the basis of hydraulic analysis, flood storage (95 acre-feet) and spillways are insufficient to safely pass the 1/2 Probable Maximum Flood (PMF) which the Office of the Chief of Engineers (OCE) Guidelines specify to be the design flood for a dam in the small size and high hazard categories. The dam is in the small size category and has a downstream hazard potential classification of high by the USCE and '1' by the State of Tennessee.

Bush and published by . This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grand Valley Dam No. 1 is located in Hardeman County, Tennessee several miles east of Hickory Valley, Tennessee and is an earth fill embankment 37 feet high and 1800 feet long. The crest width is 26 feet. Facilities for discharge from the reservoir are located near the south abutment and consist of a concrete service spillway 11 feet by 8 feet with two 9.0 foot by 0.83 feet openings and a 42 inch CM pipe barrel through the dam and an emergency spillway constructed as a low area in the top of the dam. The emergency spillway has gentle side slopes and a 50 foot wide bottom section. The entrance and exit slopes are 1V on 3H on the upstream slope and 1V on 4H on the downstream slope. No protection is provided for the exit slope. The upstream slope is vertical from the waterline for approximately two feet. The slope from that point to the crest is one vertical on three horizontal. The downstream slope is generally one vertical on four horizontal. Both the upstream and downstream slopes have ineffective vegetation. The dam is in the intermediate size category and has a downstream hazard potential classification of high by the USCE and 'I' by the State of Tennessee. On the basis of hydraulic analysis, the dam has flood storage (572 acre-feet) and spillways inadequate to safely pass the Probable Maximum Flood (PMF).

This book was released on 1981 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a linear earthen structure 163 feet long and 26.4 feet high with a crest width of 11 feet. The upstream and downstream slopes are both 1.4H:1V. The surface area of the lake is 3.7 acres at normal pool and 5.8 acres at the top of the dam. The 104 acre drainage area of the reservoir is predominantly woodland and meadow with an average ground slope of approximately 14%. Reportedly, water seeps slowly through fissures in the natural ground into a 0.4 acre lake 200 feet right of Lever. This dam was built for the purpose of maintaining pressure on the seeps and thereby maintaining the pool level of the larger lake. OCE guidelines recommend that small, high hazard dams such as Lever pass the one-half Probable Maximum Flood (1/2 PMF) to the full PMF. Analysis reveals that the dam will be overtopped by 0.6 feet for 0.6 hours under the 1/2 PMF. The reservoir contains the 100-year frequency storm maintaining 3 feet of freeboard. The dam is given a condition classification of 'unsafe - nonemergency' because of its spillway limitations and because the steepness of its downstream slope constitutes a stability concern. It is recommended that a qualified engineer be retained to study the embankment stability and the hydraulic limitations of the spillway and make recommendations for their correction.

This book was released on 1981 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a linear earthen structure 310 feet long and 44.7 feet high with a crest width of 14 feet. The upstream and downstream slopes are 2.6H:1V and 2.5H:1V respectively. The embankment is free of undesirable vegetation except for some scattered 1/2 - 2 in. diameter heavenwood trees. Most of these are at the downstream right toe and abutment tie-in. No signs of sliding, cracking, or differential settlement were observed on the dam or in the area immediately downstream. Erosion was insignificant. On the basis of a federal hazard potential classification of 'high' and an 'intermediate' size classification, the dam should pass the full Probable Maximum Flood (PMF) of 28.5 in. of rain falling in 6 hours. Analysis reveals that the dam will overtop by about 3.4 ft. for 1.8 hours during this storm. The 1/2 PMF will also overtop the structure. The dam received a condition classification of 'significantly deficient' because of its spillway limitations. It is recommended that a qualified engineer be engaged to develop project modifications that will allow the dam to pass the PMF and that the owner perform various maintenance operations.

This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a linear earthen structure 325 feet long and 47.1 feet high with a crest width of 13 feet. The upstream and downstream slopes are 2.4H:1V and 2.7H:1V respectively. It is in the intermediate size and high ahzard potential classifications. The lake area is 7 acres at normal pool, increasing to 23 acres at the top of the dam. The service spillway is a 2 ft x 6 ft (inside diameter) concrete riser with a 15-in. steel cylinder concrete pipe. The drawdown consists of a 16-in. diameter formed opening feeding into the riser controlled by a 24-in. slide headgate. The emergency spillway is an open channel excavated in rock at the right side of the embankment. It has a base width of 25 feet and is trapezoidal in shape. The dam is well grassed and free of undesirable vegetation. Its slopes are uniform and well defined and exhibit no signs of structural instability. Some minor erosion exists on the downstream slope in two areas where construction equipment and 4-wheel drive vehicles have destroyed the grass cover. No cracks, signs of seepage, sliding, or differential settlement were observed on the dam or in the area immediately downstream. The dam is given a safety classification of 'significantly deficient' because of its spillway limitations. It is recommended that a qualified engineer be engaged to develop project modifications that will allow the dam to pass the PMF, and that the owner perform various maintenance operations. (Author).

Moore and published by . This book was released on 1981 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dam is located in Monroe County about 0.7 miles southwest of Sweetwater, Tennessee and is an earthfill embankment 46 feet high and 1100 feet long. The crest width is 19 feet. The embankment slopes are 1V:3H and berms are located on both the upstream and downstream slopes. The dam controls a 1005 acre drainage area and is intended to impound the 9.4 acre Sherman F. Owen Lake. The service spillway is a 2 stage standard SCS cast in place concrete riser leading to a 30-inch diameter reinforced concrete pipe. The service spillway outlet has an SCS standard baffled impact basin. The drawdown drain is a 24-inch diameter orifice controlled by a slide gate at the base of the riser. The emergency spillway is an uncontrolled earth saddle on the left abutment. The channel has a trapezoidal cross-section with a 200 foot base and 1V:3H side slopes. The reservoir has a leak which has prevented filling of the lake and is apparently due to an open solution channel that is draining into another watershed. The leak is not expected to affect the structural stability of the dam. No indications of instability were observed. The Dam is in the intermediate size category and has a downstream hazard potential classification of high under Corps of Engineers criteria and 1 under State criteria. On the basis of hydraulic analysis, the dam has adequate storage/spillway capacity to pass the probable maximum flood (PMF) under antecedent moisture condition II (AMC II). Under OCE guidelines, a dam in the intermediate size and high hazard potential classification is required to pass the PMF. (Author).

Moore and published by . This book was released on 1981 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is based on the findings of a Phase I inspection of Chancellor and Son Dam in Hardeman County. The earthfill embankment is 24 feet high and 550 feet long with a crest width of 15 feet. The service spillway is a 36 inch concrete culvert passing through the embankment near the crest. The drawdown drain is a 10 inch corrugated metal pipe with a slide gate at the inlet and a plug in the outlet. The emergency spillway is a triangular earth channel at the left end of the dam. The available data is insufficient to assess the potential affect of the seepage on the embankment. The reservoir has sufficient storage/spillway capacity to pass the PMF, but the embankment portion of the emergency spillway would probably deteriorate rapidly under high stage flows. Also, the service spillway is not properly designed to pass large flows. The spillways are therefore considered to be seriously inadequate. Because of these findings, Chancellor and Son Dam is considered to have a condition classification of 'unsafe nonemergency'.
