This book was released on 1978 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fawn Lake Dam is owned by the Lake Wynonah Property Owners Association and is located in South Mannheim Township in Schuylkill County, Pennsylvania. The dam was designed by the original owner, American Realty Service Corporation of Memphis, Tennessee. The embankment was completed on May 12, 1971, and has been in service ever since. The facility is judged to be in reasonably good operating condition. Calculations indicate that the spillway systems are capable of passing the probable maximum flood (PMF). Therefore, the spillway is considered to be 'Adequate'. Seepage was noted emanating from the downstream slope and along the toe of the dam, but there were no indications at this time that this condition is potentially hazardous. No indications of slope distortion, embankment slides or other condition indicative of a potentially unstable embankment were noted.

This book was released on 1978 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Wynonah Dam is a 92 foot high, zoned embankment. The dam measures 950 feet along the crest impounding a 175 acre reservoir. The dam was designed to use locally available borrow materials and contains two primary material zones. The upstream zone, consisting of approximately 2/3 of the dam cross-section, is composed of impervious materials classified as clayey sands and silty clayey sands. The downstream section, which consists of approximately 1/3 of the cross-section, is composed of a previous coarse-fill zone. There is a 2-foot thick blanket drain beneath the coarse-fill zone. The toe drain discharges into the natural stream channel. A 24-foot wide cut-off trench was excavated into sound rock along the centerline to control seepage. A double line split-spaced grout curtain was constructed below the core trench. A maximum hole spacing was 5 feet on center and holes were staggered 5 feet up- and downstream of the centerline. The upstream slope contains benches at elevations 634 and 588. The slope is riprapped from the upper bench to elevation 646 (3 feet below the crest of the dam).

This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pole Run Dam No. 4 is a 30 foot high earthen embankment across Pole Run, a tributary of North Mahanoy Creek. The 780 foot long dam impounds a nine acre reservoir within an 0.58 square mile drainage basin. Very limited data exists regarding the physical features of the dam. The average measured downstream slope is 2H:1V, and the slope is covered with stone and vegetation. Since the average freeboard of the structure is less than one foot at normal pool level, the upstream slope could not be measured. A portion of the upstream slope is covered with stone, and this stone could be seen to extend at least two feet below the water and it is probable that it extends several feet below that elevation. The crest width ranges from 15 feet to 27 feet. The spillway is located at the right abutment, and consists of an open concrete channel with concrete retaining walls. The water supply intakes could not be inspected as they are below water and the pipes are buried in the embankment. The outlet pipes were inspected and three pipes were found. Near the toe of the dam, valves were located which are presumably used to control flow through the pipes.

Heiser and published by . This book was released on 1979 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fawn Lake Dam is a homogeneous earth embankment structure provided with a blanket drain and a rock toe. The design includes provision of a key trench. The embankment is approximately 400 feet long and has a maximum height of 41 feet. A 90-foot long overflow spillway is located between the embankment and the left abutment. The dam is provided with 5 feet of freeboard above the spillway, crest. Spillway training walls extend both upstream and downstream of the spillway, as shown on Plate 4. A concrete apron extends 100 feet downstream of the spillway, and varies in width from 90 feet at the spillway to 25 feet at the outlet channel. A trapezoidal outlet channel is lined with grouted riprap for approximately 250 feet downstream of the apron. A 24-inch diameter reinforced concrete pipe is provided as a low level outlet. Flow through the pipe is controlled by a gate valve at the upstream toe of the embankment. The operating stem expands from the valve to the top of dam, and is supported on concrete columns embedded in the embankment.

This book was released on 1978 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Antietam Dam is a 60-foot high masonry structure with an upstream compacted fill embankment with an impervious core approximately 8 feet wide. The dam is approximately 230 feet long with a crest width of 17 feet. The embankment impounds a 16-acre reservoir within a 5.5 square mile drainage basin. The upstream slope is 2.25H:IV, and is riprapped from the crest to elevation 498 with hand-placed stone. The downstream slope is composed of stacked masonry block and has a curved surface, as shown on Plate 5, Appendix E. The dam was founded on trap rock, and does not have a cutoff trench or a grout curtain. There is a 4-foot high parapet wall along the downstream side of the crest. The spillway is excavated into solid rock on the left abutment, and has a skewed spillway with a crest width of 66 feet discharging into a channel which narrows to 30 feet at the end. Thereafter, water discharges into the natural streambed below the dam. The intake tower is located 125 feet upstream from the crest, and contains one discharge pipe, as shown on Plate 5. It is noted that this discharge pipe is no longer operational, and that the reservoir no longer serves as a water supply source. The dam contains a pond drain with a control valve at a valve house located at the downstream toe of the dam.

This book was released on 1979 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deer Lake Dam is an earthfill structure with a concrete core wall. The length of the earthfill structure is about 1,430 feet of which 630 feet crosses the valley and 800 feet is along the right bank of the reservoir. A 245 foot long spillway is located across the original streambed. The concrete gravity spillway section has a crest elevation of 3 feet below the low point of the embankment and contains three sluice gates (Appendix F, Plate IV). The lake was used as a recreational facility, but considerable siltation has occurred in the reservoir. Two sluice gates are partially opened to permit drying out of the silt for future removal. To increase flow in the left corner of the reservoir, and to prevent stagnant water in this area used for swimming, a box culvert was constructed through the embankment. This culvert is in very poor condition. The embankment crest elevation is about 12 feet above streambed, although most of the length is not more than 8 or 9 feet.

Mihalcin and published by . This book was released on 1981 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and hydrologic and hydraulic analysis, the dam is considered to be in fair condition. The size classification of the facility is small and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility ranges between the 1/2 PMF (Probable Maximum Flood) and the PMF. Since the facility is classified near the lower bounds of the small category, the SDF is considered to be the 1/2 PMF. Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 15 percent of the PMF prior to embankment overtopping. A breach analysis indicates that failure under less than 1/2 PMF conditions could lead to increased downstream damage and potential for loss of life. Thus, based on screening criteria provided in the recommended guidelines, the spillway is considered to be seriously inadequate and the facility unsafe, non-emergency.
