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 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 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bear Creek Dam is a hollow reinforced concrete structure of the 'Ambursen' type approximately 450 feet long and 64 feet high at its central portion. The dam is founded on a full concrete mat with an upstream concrete cutoff wall extending into natural rock. The dam was built in 1915. The dam is classified as an 'Intermediate' size dam by virtue of its 64-foot height. The dam is also considered a 'High' hazard structure because in the event of failure there is a possibility of loss of life and extreme property damage downstream.

This book was released on 1978 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birdsboro Dam is an approximately 40-foot high rolled earth embankment constructed across Indian Run Creek. The 430-foot long dam impounds an 8-acre reservoir. Very limited data exists regarding physical features of the dam. However, it is known that local borrow material from within the reservoir area was used for the construction. The downstream slope is a 1.5H:IV slope, and the upstream slope is covered with hand-placed riprap on a slope of approximately 2.5H:IV. It is not known if there is a cutoff wall, nor is it known if a grout curtain was installed.

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.

This book was released on 1979 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Park Place Dam No. 3 is a 32 foot high earthen embankment across an unnamed tributary of North Mahanoy Creek. The 685 foot long embankment impounds a 109 acre-foot reservoir within an 0.27 square mile drainage basin. Since very limited data exists regarding the physical features of the dam and appurtenances, most of the features described herein were obtained from field measurements taken during this inspection. The downstream slope was measured to be 2H:1V and is covered with riprap and occasional vegetation, as shown on Photographs 7 and 8. The average upstream slope could not be measured as the very small freeboard between the crest of the dam and the normal pool prevented a reliable measurement. The upstream portion of the slope between the crest and to at least several feet below the waterline was covered with riprap. The crest width ranges from 10 to 12 feet and averages approximately 11 feet wide. A 10-inch water supply pipe is located at the base of the embankment. An eight-inch water supply line branches off in the downstream valve house at the downstream toe. Discharge through both lines is controlled by valves located in the valve house.

This book was released on 1979 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sweet Arrow Lake Dam is an earthfill embankment with a maximum height of 35.5 feet. The length of the dam crest is about 480 feet. The ends of the embankment tie into the remains of an older and higher dam which failed, due to overtopping, in 1862. A cutoff trench was excavated to solid rock and a grout curtain was installed. The spillway, which has a crest elevation of 14.5 feet below the top of the dam is located in the west (left) abutment, and is separated by a high ridge from the embankment. The 50 feet wide spillway was excavated in rock and is unlined. An intake tower is located at the toe of the upstream slope. The intake is controlled by two 18-inch gate valves and the discharge is through a concrete conduit beyond the downstream toe of the dam.
