Bush and published by . This book was released on 1981 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Houser Creek Dam No. 2 is located in Obion County, Tennessee approximately 2 miles north of Union City, Tennessee. It is an earth fill embankment 26.5 feet high and 1350 feet long and impounds a 23.8 acre lake. The crest width is 14 feet. Facilities for discharge from the reservoir include a concrete service spillway with inside intake dimensions of 9 feet by 3 feet. The riser is 15 feet high located near the center of the impoundment with a 36 inch concrete pipe barrel through the dam. The emergency spillway is located in the left abutment and has a bottom width of 200 feet and side slopes of 1V on 3H. Its depth below the low point of the dam is 4.5 feet. A slide gate is attached to the upstream face of the service spillway at the bottom to draw down the impoundment. (At the time of inspection, this gate was open and the impoundment was drawn down.) The embankment slopes are approximately 1V on 3H on the downstream slope and 1V on 3H on the upstream slope. The lack of proper maintenance was found to be the major problem during the inspection of the Houser Creek Dam No. 2. A dense growth of trees and brush covered both the downstream and upstream slopes of the dam. The concrete riser also showed signs of vandalism with the removal of debris guards. The dense vegetation on the slopes of the dam prevented a close inspection of the conditions of the slope. (Author).

This book was released on 1981 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is based on the findings of the Phase I investigation of OFDBA Site 60-6 on February 4, 1981 in accordance with 'Recommended Guidelines for Safety Inspection of Dams' Office of the Chief of Engineers. The earth dam is 54 feet high and 726 feet long with a crest width of 25 feet. At normal pool the dam impounds a 125 acre lake (2137 acre-feet) used for flood control. It is in the intermediate size and high hazard potential category. The downstream slope is 2.6H:1V and the upstream slope is 3H:1V. The embankment has moderate slopes and exhibited no signs of instability or uncontrolled seepage. Erosion is a major problem at this time as indicated by the presence of deep holes and gullies on the upper portion of the embankment and in the emergency spillway. Large holes were also observed below the right toe of the dam near the creek channel. The emergency spillway is a 250 foot wide grassed channel at the left abutment. There was no evidence that the spillway had ever carried flow. The principal spillway is a 36 inch diameter CMP riser with a 30 inch concrete pipe outlet. An 18 inch manually operated headgate is located at the base of the riser and is used to lower the lake level. A hydraulic and hydrologic analysis indicated that the spillway is capable of passing the recommended probable maximum flood (PMF). The dam is classified as 'unsafe non-emergency' due to the erosion on the embankment and the large holes just below the dam.

This book was released on 1981 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is based on the findings of a Phase I investigation of OFDBA Site 41-1 (Glady Hollow) Dam on February 4, 1981. This study was done in accordance with 'Recommended Guidelines for Safety Inspection of Dams', Department of the Army, Office of the Chief of Engineers. The earth dam is 32 feet high and 278 feet long with a crest width of 15 feet. It is in the small size and high hazard potential category. The structure impounds a 5.5 acre lake used for flood control. The embankment has moderate slopes 1V:3.4H upstream and 1V:2.8H downstream. No signs of uncontrolled seepage or distress was observed. A bare path has been cut into the downstream slopes by vehicles being driven up the slope. The remainder of the embankment has a well established grass cover. The principal spillway is a 24-inch CMP riser with an 18-inch CMP outlet. The drawdown facility is a 12-inch slide headgate located at the base of the riser. The emergency spillway is a 94-in wide grassed channel at the right abutment. It was in good condition and appears to have never carried flow. Analyses indicate that the spillway is adequate to pass the recommended 1/2 PMF. The dam is classified as 'deficient' due to the presence of an unvegetated area on the downstream slope.

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.

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 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).

This book was released on 1981 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The earth dam is 15 ft. high, 675 ft. long, and has a crest width of 13 feet. It is in the small size and high hazard potential category. The dam impounds a 5.5 acre lake used for recreation and water supply. The embankment slopes are moderate and have a well established grass cover. Vehicles have cut deep ruts into the crest. The principal spillway is a 36 inch diameter CMP riser with a 30 inch diameter CMP outlet. A slide headgate is located at the base of the riser to regulate the lake level. The emergency spillway is a irregular shaped earth channel at the left abutment. The channel is relatively flat and in good condition. The dam is classified as 'significantly deficient' because the spillway will not safely pass the recommended one-half Probable Maximum Flood.

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).

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.

This book was released on 1981 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is uniform well grassed and clear of any deleterious vegetation. The upstream slope of the embankment shows appreciable sloughing near the principal spillway. Scattered minor depressions appear sporadically along the downstream slope, presumably the result of dispersive soil. There are no indications of seepage on the slope or in the area downstream of the dam. No signs of differential settlement or other slope instabilities were observed. Appreciable erosion occurs near the water surface and along the upstream left side slope, apparently the result of cattle congregating in these areas. The dam is in the high hazard potential and small size classifications. OCE guidelines require such dams to pass the one-half probable maximum flood (1/2 PMF) to full PMF. Hydraulic and hydrologic analyses reveal that the emergency spillway is capable of passing the 1/2 PMF without causing the dam to overtop not breach during the storm. The upstream dam will overtop under the 1/2 PMF. Should failure of the upstream dam occur, analysis indicates that Mary's Creek Dam will be overtopped by 0.2 feet for 1.8 hours. The dam is given a condition classification of 'deficient' because of the erosion near the emergency spillway entrance and elsewhere along the upstream slope.

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 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portland City Lake Dam has an 35.5 acre lake and is located in Sumner County, Tennessee 2.5 miles northeast of Portland, Tennessee and is an earth fill embankment 32.8 feet high and 600 feet long. The crest width is 20 feet. Facilities for discharge from the reservoir are a low level outlet consisting of a 16 inch cast iron pipe through the dam with a valve on the outlet end and a water supply pipe of unknown diameter with a valve located in the lake. The emergency spillway is in the south abutment and consists of a concrete bottom 21 feet wide and layback concrete walls 4 feet high. The spillway is crossed by a road with four 48 inch concrete pipes set on top of the concrete chute to support the road. The embankment slopes are approximately 1V on 3H on the downstream slope and 1V on 3.1H on the upstream slope. Both slopes have undesirable vegetation. The emergency spillway has major problems which could lead to considerable damage including possible failure during a period of high flow in the spillway, also the spillway is inadequate to pass the 1/2 PMF (design flood) without overtopping the dam. Other problems include probable seep areas at the north abutment as the lake level approaches or exceeds normal pool elevations and the valve location on the drawdown pipe.
