Book excerpt: This report is based on the findings of a Phase I inspection of Candlewood Lake Dam. The zoned earthfill embankment is 43.6 feet high and 800 feet long with a crest width of 24 feet. The dam is in the intermediate size and high hazard potential category. The reservoir has sufficient storage/spillway capacity to safely pass the full PMF. Erosion is evident in the emergency spillway channel, on the embankment abutment contacts, and on the downstream slope. Some indications of dispersive soils were noted on the downstream slope. Also, the downstream slope appeared to be excessively moist and some standing water was seen. Due to these findings, Candlewood Lake Dam is considered to be 'significantly deficient'.

Moore and published by . This book was released on 1981 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the findings of a Phase I inspection of Spring Lake and Old Hickory Lake Dams in Hardeman County; Spring and Old Hickory Lake Dams are in series with each other and with Chancellor Dam upstream. The dams are of similar construction nad have the same owner. Spring Lake Dam is a zoned earthfill embankment 21.5 feet high and 400 feet long with a crest width of 12 feet. The side slopes are 3H;1V upstream and 3.7H:1V downstream. The service spillway is a concrete riser with two 1 ft x r openings leading to a 15 inch concrete pipe passing under the dam. The drawdown drain is a 15 inch diameter gate valve at the base of the riser. The emergency spillway is a trapezoidal earth saddle on the right abutment with an estimated capacity of 3500 cfs. Old Hickory Dam is a zoned earthfill embankment 20.5 feet high and 530 feet long with a crest width of 12 feet. The side slopes are 3.5H:1V upstream and 3.9H:1V downstream. The service spillway is a concrete riser with two 1 x 4 openings leading to a 24 inch concrete pipe passing under the dam. The draw-down drain is a 24 inch gate valve at the base of the riser. The emergency spillway is a trapezoidal earth saddle on the left abutment with an estimated capacity of 4670 cfs. Both dams are in the small size high hazard potential categories. Neither dam shows any overt signs of instability.

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'.

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).

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.

This book was released on 1981 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woodrun Dams No. 1 (west dam) and No. 2 (east dam) are colinear earthen structures 885 feet and 945 feet long respectively. The impoundments of each structure are interconnected by a channel forming a single 43 acre lake. Dam No. 1 is 27.5 feet in height with a crest width of 15 feet. Its upstream and downstream slopes are 1V:2.5H and 1V:2.8H respectively. Dam No. 2 is 33.2 feet in height with a crest width of 10 feet. Its upstream and downstream slopes are 1V:2.7H and 1V:3.6H respectively. Both dams are uniform in cross section and host no deleterious vegetation. The reservoir has a drainage area of 249 acres. It is predominately wood-land with an average ground slope of approximately 14%. The downstream slope of Dam No. 1 is wet with seepage beginning approximately 20 feet below the crest extending to the toe and becoming attenuated toward the ends of the dam. The seepage area is accompanied by moderate erosion near the maximum section. A property owner has dug a narrow ditch along part of the toe to channel seepage from his land. Pooled seepage exists along much of the channel and a clear flow of approximately 1/2 gpm was observed emanating from its upstream side. Seepage also exists on the downstream slope of Dam No. 2. It extends over a large area beginning approximately 200 feet right of the principal spillway, emerging from the slope 10-15 feet below the dam crest. The dam is not as wet and eroded as Dam No. 1, indicating that seepage is not as profuse. The principal spillway consists of a 30 in. steel pipe riser and a 30 in. outlet culvert of similar construction.

This book was released on 1981 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The crest undergoes little change in elevation and has a fairly constant width but ruts from vehicular traffic are predominant along much of the surface. The downstream slope of the dam is traversed by cattle trails nearly paralleling one another at different elevations from the toe to the dam crest. Some vehicular traffic has apparently also been occurring on the slope in the area of the principal spillway outlet. The upstream slope of the dam has been sloughed off below elevation 352 along most of the length of the dam. The embankment is reasonably well grassed and free of undesirable vegetation. There are some wet areas along the downstream toe but they are apparently pooled surface runoff and not the result of seepage. Because the reservoir was empty during the inspection, any active seepage flow that may normally occur did not appear, but no indications of a previous seepage flow were observed on the slope. The principal spillway consists of a reinforced concrete riser feeding a 156 foot, 30 inch diameter reinforced concrete culvert. The emergency spillway is an uncontrolled saddle type trapezoidal earthen channel at the left end of the dam. It has an 80 foot base, 1V:4.6H side slopes, and 2.1 feet of available head. OCE guidelines recommend that high hazard dams of intermediate size pass the full Probable Maximum Flood. Hydraulic and hydrologic analysis reveal that the dam will be overtopped by a maximum of 2.4 feet for 7.2 hours (AMC II) under the influence of this storm. The dam is given a condition classification of 'unsafe nonemergency' because of its seriously inadequate spillway.

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.

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.
