This book was released on 1979 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: North Fork Dam is a homogeneous earthfill dam 622 feet long and 58 feet high. The principal spillway is a two-stage drop inlet spillway with a 30' diameter reinforced concrete pipe. The riser unit is 2.5 feet by 7.5 feet and is 33 feet high. The emergency spillway is located on the left abutment and is formed by a trapezoidal shaped open cut in glacial sand clay and gravel. The bottom width of the spillway channel is 100 feet. The spillway exit channel is 482 feet long and discharges on the left hillside below the toe of the dam. The inspection and review of data of North Fork Dam did not reveal any problems which require emergency action. The dam appears to be stable, well maintained, safely operated and in good condition. However, the spillway and reservoir are capable of controlling 60% of Probable Maximum Flood without overtopping the earth embankment. Based upon criteria established by the Corps of Engineers, the spillway is termed inadequate, but not seriously inadequate. In addition, the earth berm in the emergency spillway exit channel is low and overtopping of the berm during flood conditions will cause erosion of the embankment/abutment contact. This spillway berm will be overtopped at approximately 25% of the PMF.

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.

Jeffrey Kimball and published by . This book was released on 1979 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Chillisquaque is an earth-fill dam 2000 feet long and 54 feet high. The dam is a zoned earth embankment with a center core consisting of silty clay material and the upstream and downstream portions consisting of weathered shale. The upstream and downstream slopes were constructed at 2.5H:1V with berms at elevation 582.0. The crest of the dam is 12 feet wide and forms an access road at elevation 605.5. The outlet works consist of a concrete control tower connected to two 36 in. steel pipes encased in concrete. The outlet works has a positive upstream shut off in the form of a bulkhead. The flow through these pipes is regulated by a 36 in. sluice gate, an 18 in. cone valve or an 8 in. by pass valve. At the toe of the dam is a valve house to control flow through these pipes. The earthen emergency spillway is located on the left abutment and contains a concrete sill 750 feet long. The spillway discharge channel is 1300 feet long and discharges to a natural stream.

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.
