Bluhm and published by . This book was released on 1981 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: 8TH Avenue Reservoir is in the high hazard and small size classification and according to OCE guidelines must pass the 1/2 to full PMF. Because the only inflow would be the rainfall itself, the reservoir, with its three feet of freeboard, would be able to contain the full PMP of 29.3 inches. The reservoir appeared to be in good condition and structurally stable. No significant seepage, wet areas, sinkholes or cracks were found on or near the reservoir. Seepage was occuring in the dry well of the gate house and calcium carbonate deposits were observed on the exterior stone of the reservoir wall; however, neither considered serious at this time. Structure is given a condition classification of 'deficient' because of the seepage in the gate house well and the minor concrete spalling on the walkway of the reservoir.

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 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 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cumberland Springs Dam has an 8.3 acre lake and is located near the head of Hurricane Creek in Moore County, Tennessee. The concrete gravity structure has a maximum constructed height of 33 feet and a length of 192 feet, including a 36 foot long ogee spillway. The spillway section also includes a drawdown pipe that is gated on the upstream face. The concrete dam is reinforced with six buttresses on the downstream face. The exposed surfaces of the buttresses are badly weathered with horizontal cracks 6 inches deep on the vertical faces. A horizontal crack was observed on the downstream face of the dam approximately 10 feet above the foundation sill. This crack appears to be in a construction 'cold' joint. Seeps were found in the east end wall and along the foundation sill between buttresses 1 and 2 and 2 and 3. Numerous springs were flowing immediately below the dam and both abutments. Cumberland Springs Dam is in the small size category and has a downstream hazard potential classification of high by the Corps of Engineers and 'I' by the State of Tennessee. On the basis of hydraulic analysis. Cumberland Springs Dam flood storage (15.8 acre-feet) and emergency spillway are inadequate to safely pass the 1/2 Probable Maximum Flood (PMF), which Office of the Chief of Engineers (O.C.E.) Guidelines specify to be the design flood for a dam in the small size and high hazard potential categories. At this time, the dam is considered 'unsafe-nonemergency'.

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.

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.

Bush and published by . This book was released on 1981 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nolan Dam has an 8.44 acre lake and is located in Shelby County, Tennessee, south of Winchester Road and east of Ross Road, and is an earth fill embankment 14.7 feet high and 640 feet long. The crest varies from 9 feet to 12 feet in width. Facilities for discharge from the reservoir are located in the east abutment and include an inlet section with a bottom width of eight feet and vertical broken concrete masonary walls two feet high. The emergency spillway is crossed by a farm road approximately 50 feet from the entrance and the fill contains four 18 inch corrugated metal pipes protected by a concrete headwall on both sides of the road. A four inch cast iron draw down pipe with a gate valve at the discharge end is located at approximately the center of the dam. The embankment slopes are approximately 1V on 3H on 2.3H to the top of the dam on the upstream slope. Neither slope has undesirable vegetation. A broken concrete masonry wall provides the vertical section of the upstream slope. Nolan Dam is in the small size category and has a downstream hazard potential classification of high by the Corps of Engineers and I 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 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 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'.

This book was released on 1981 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a linear earthern structure 450' long and 47.5 high with a crest width of 18'. The upstream and downstream slopes are 3.2H:1V and 3. OH:1V respectively. The surface area of the lake is 5.4 acres at normal pool and 15.5 acres at the top of the dam. On the day of the inspection the reservoir was about 2/3 full for the first filling since construction. At the left abutment is an uncontrolled earth and rock saddle spillway with a base width of 72'. The principal spillway consists of a 2.5' x 7.5' reinforced concrete riser feeding a 30' steel cylinder concrete pipe. The drawdown is a 24' formed opening at the upstream toe of the riser regulated by a manually operated 24' sliding headgate. The embankment is uniform and well grassed with no signs of cracking, sliding, or differential settlement observed on the embankment or in the area immediately downstream. There are no trees or other deleterious vegetative growth. The dam is in the intermediate size and high hazard potential category. On the basis of these classifications, the structure is required to pass the full probable maximum flood (PMF) of 28.2' of rain falling in 6 hours. Analysis reveals that the spillway is capable of passing the flood without causing the dam to overtop. Since the dam has no significant defects or inadequacies, it is considered to be 'not deficient'.
