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.

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.

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.

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'.

Moore and published by . This book was released on 1981 with total page 93 pages. Available in PDF, EPUB and Kindle. 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 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'.

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 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 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'.
