This book was released on 1979 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galion Bay Dam consists of an earth embankment approximately 400 feet long with a maximum height of 37 feet from the downstream invert of the outlet conduit and a crest width of 20 feet. Galion Bay Dam is one of the three dams which impound Lake Rene. The other two dams are Wolf Creek Dam, located at the west end of Lake Rene, and Lake Rene Dam, located on the east side of the reservoir. Lake Rene Dam, which was constructed in 1955, was the original dam at the site. Galion Bay Dam and Wolf Creek Dam were constructed in 1971 in conjunction with the enlargement of Lake Rene. The flood discharge facilities for Lake Rene consist of primary and emergency spillways associated with Galion Bay and Wolf Creek dams. The Galion Bay Dam flood discharge facilities are comprised of a drop inlet primary spillway located at the center of the embankment and an emergency spillway on the right abutment (looking downstream). The primary spillway structure consists of a single-stage reinforced concrete riser, a 36-inch-diameter reinforced concrete conduit, and a plunge pool at the downstream end of the outlet pipe. The emergency spillway is a 30-foot-wide trapezoidal earth channel excavated into the right abutment. The reservoir outlet pipe for the dam consists of a 15-inch steel pipe extending from the upstream toe of the dam to the drop inlet structure.

This book was released on 1978 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection and available engineering data, Gravel Lick Dam and its appurtenances are considered to be in fair condition. The spillway and dam are capable of passing and/or storing the flow resulting from a storm of PMF magnitude without overtopping the embankment. As a result, the spillway is considered adequate. Seepage through the downstream slope, steadily increasing pore pressures near the downstream toe and erosion below the downstream bench level are apparent. It is recommended that: (1) the owner engage the services of a qualified registered professional engineer to investigate the seepage through the downstream face and evaluate the increasing pore pressure conditions at the toe; (remedial measures should then be implemented as required); (2) the erosion gullies along the downstream face be backfilled and seeded; (3) a formal warning system be implemented to protect those persons downstream who may ultimately be affected by an embankment breach; and (4) the dam should be inspected on a periodic basis to check for hazardous conditions which might develop.

This book was released on 1979 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Rene Dam consists of an earth embankment approximately 900 feet long with a maximum height of 82 feet from the downstream toe and a crest width of 60 feet. Lake Rene Dam is one of three dams which impound Lake Rene. The other two dams are Wolf Creek Dam, located at the west end of the reservoir, and Galion Bay Dam, located on the south side of the reservoir. Lake Rene Dam, which was constructed in 1955, was the original dam at the site. The original dam impounded a reservoir with a surface area of approximately 240 acres at normal pool elevation (Elevation 1658). The Wolf Creek and Galion Bay dams were constructed in 1971, increasing the surface area of the reservoir to approximately 310 acres at normal pool level of Elevation 1662.5. Based on the evaluation of the existing conditions, the condition of Lake Rene Dam is assessed to be unsafe due to numerous seeps and slumps on the downstream face of the dam and due to lack of operable outlet works for the reservoir. However, it is not an emergency condition.

Anderson and published by . This book was released on 1979 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions on March 14 and April 16, 1979, the condition of Little Blue Run Dam is considered to be good. No conditions were noted at this time that would significantly affect the structural performance of the dam. The flood discharge facilities for the dam were designed to pass the probable maximum flood (PMF) without overtopping the embankment. Therefore, according to the recommended criteria, the flood discharge facilities of the dam are adequate. Presently, the pool elevation is approximately 170 feet below the dam crest level. The pool elevation is expected to reach spillway crest level in about the year 2010. The following recommendations should be implemented on a continuing basis: (1) The cracking observed on the crest should continue to be evaluated by the design engineers. Also, attention should be given to the slump and seepage observed on the left abutment. Erosion ditches on the right abutment should be filled; and (2) A formal warning system should be developed to alert the downstream residents in the event of emergencies.

Mihalcin and published by . This book was released on 1979 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, past performance, and available engineering data, the facility is considered to be in good condition. The size classification of the facility is intermediate and the hazard classification is considered to be high. The emergency spillway is capable of discharging the peak inflow resulting from a storm of PMF intensity and is, therefore, considered adequate. It is recommended that the owner: (a) Repair the damaged pond drain gate control and replace the missing manhole cover atop the service spillway riser. Consideration should be given to redesigning the gate control mechanism to protect it from future vandalism. (b) Consult with the U.S.D.A., Soil Conservation Service, to assess the erosion on the upstream slope in the area of the service spillway riser and implement any remedial measures deemed necessary. (c) Curtail the unauthorized vehicular travel across the embankment and repair and reseed any damaged (bare) areas. If control of unauthorized travel is not practical, some provision should be made to protect the embankment from rutting and erosion by placing a layer of gravel or stone across the crest. (d) Develop a formal operation and maintenance manual to ensure the continued proper care of the facility. In addition, a formal warning system should be implemented which provides detailed procedures to protect the lives and property of downstream residents. Included in the plan should be provisions for around-the-clock surveillance of the facility during periods of unusually heavy percipitation.

Andersen and published by . This book was released on 1980 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bear Rock No. 1 Dam consists of an earth embankment approximately 560 feet long with a maximum height of about 26 feet from the downstream toe and a crest width of about 8 feet. The upstream and downstream faces and crest of the dam are covered with riprap. The flood discharge facilities of the dam consist of a stone masonry structure with a flow width of 58 feet. The discharge from the spillway flows into an unprotected discharge channel which follows the left side of the valley. A dike is provided along the right side of the spillway discharge channel to prevent flows towards the toe of the dam. The outlet facilities consist of a 16-inch cast-iron blow-off pipe and 10- and 12-inch cast-iron supply pipes. Based on the evaluation of the existing conditions, the condition of Bear Rock No. 1 Dam is considered to be unsafe/nonemergency due to the seriously inadequate spillway capacity (30% of PMF). The condition of the embankment is considered to be fair.

This book was released on 1980 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graceton Dam consists of an earth embankment approximately 250 feet long with a maximum height of approximately 26 feet from the downstream toe. The crest width is approximately 10 feet. A 10-foot-wide berm is located on the downstream slope at about midheight of the embankment. The downstream slope of the embankment is approximately 1.5H to 1V above the berm and 2.5H to 1V below that level. The flood discharge facilities for the reservoir consist of a concrete overflow structure located on the left abutment (looking downstream). The overflow section is approximately 15 feet wide and 3 feet deep and discharges onto an approximately 30-foot-long concrete chute. According to the previous inspection reports, the outlet facilities consist of two cast-iron pipes 4 and 6 inches in diameter. the location of the pipes and the manner in which flow through these pipes is controlled is unknown. In the design drawings, flow through these pipes is shown to be controlled by valves located in a valve chamber on the downstream side of the dam. However, this valve chamber could not be located at the site during this inspection. As it presently exists, the dam has no functional emergency drawdown facilities. (Author).

Andersen and published by . This book was released on 1980 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shirf's Run Dam consists of an earth embankment approximately 320 feet long with a maximum height of 15 feet from the downstream toe and a crest width of 10 feet. The upstream side of the dam is protected by riprap and the downstream slope is covered with grass. The spillway discharge facilities for the dam consist of an earth channel located at the right abutment. The outlet facilities consist of a 12-inch cast-iron pipe encased in concrete through the embankment. Based on the evaluation of the existing conditions, the condition of Shirf's Run dam is considered to be good. The only condition noted which requires attention is the lack of adequate erosion protection on the left side of the emergency spillway channel against the embankment. This condition is considered to pose breach potential in the event of large flows through the spillway. The flood discharge capacity of the dam was evaluated according to the recommended procedure and was found to pass approximately 50 percent of the probable maximum flood (PMF) without overtopping the embankment.

This book was released on 1979 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little Shenango Dam (PA 490) is a homogeneous earth floodwater retarding dam designed by the U.S. Department of Agriculture, Soil Conservation Service. The dam has a crest length of 430 feet, a maximum height of 45 feet, a storage volume of 472 acre-feet at spillway crest level, and a storage volume of 19 acre-feet at normal pool level. The dam was found to be in generally poor condition at the time of inspection. The inspection did disclose potential problems with seepage and piping in the dam embankment and abutments. A detailed engineering investigation of seepage, piping, erosion, and structural stability of the dam should be initiated as expeditiously as possible. Hydraulic/hydrologic evaluations revealed that the spillway will pass the Probable Maximum Flood (PMF) without overtopping the dam. The spillway is therefore considered 'adequate'.
