Jeffrey Kimball and published by . This book was released on 1979 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hunters Lake Dam is an earthfill dam 450 feet long and 27 feet high. The upstream slope is 3H:1V with concrete paving blocks acting as slope protection. The upstream slope in the lower portion is 3.5H:1V. The downstream slope is 2.5H:1V and grassed. The embankment is homogeneous with a rock toe. Upstream of the dam is a concrete control tower which contains the principal spillway. Flow enters the concrete spillway tower and drops down the tower and into a 48 inch reinforced concrete pipe to an impact basin at the toe of the dam. In addition, the concrete spillway tower has a 4 foot by 5 foot sluice gate to act as a reservoir drain. The emergency spillway is located in a natural saddle at the opposite end of the reservoir. The emergency spillway has a 300 foot long concrete slab. (Author).

This book was released on 1981 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maple Lake Dam is an earthfill embankment 14.4 feet high and 283 feet long, excluding spillway. The emergency spillway is located at the left abutment, consisting of an earth channel having a trapezoidal cross section. The bottom width of the spillway at the reservoir outlet is 56 feet. A service spillway, consisting of a 12-inch riser pipe and an 8-inch diameter outlet pipe, is located approximately 100 feet from the right abutment. The outlet works was reported to consist of an 8-inch diameter asbestos cement pipe, extending upstream of the riser pipe to the reservoir and terminating with two sections of an 8-inch diameter vitrified clay pipe, having a concrete plug at the inlet. Based on visual inspection, the Maple Lake Dam is judged to be in good condition. Under the present conditions, the spillway will pass approximately 37 percent of the PMF. Should the top of the dam be restored to its design elevation, the spillway could pass the SDF without overtopping the dam.

This book was released on 1980 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Fishpond Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. The inspection and review of data of Fishpond Dam did not reveal any problem which requires emergency action. The dam appears to be in poor condition mainly because of extensive seepage which appears to be increasing. A monitoring program developed by a professional engineer knowledgeable in earth dams should be implemented immediately. Fishpond Dam is a high hazard-small size dam. The SDF for a dam of this size and classification is 1/2 PMF to PMF. Based on the downstream potential for loss of life and property damage the spillway design flood has been selected as the PMF (Probable Maximum Flood). The spillway and reservoir are capable of controlling the PMF. Based on criteria established by the Corps of Engineers, the spillway is termed adequate. (Author).

Andersen and published by . This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Walter Dam is located on Spring Run, approximately one mile upstream of its confluence with Meshoppen Creek in Springville Township, Susquehanna County, Pennsylvania. The condition of Lake Walter Dam is considered to be good. The only significant condition noted which requires further attention is the lack of erosion protection in the emergency spillway discharge channel. The swampy condition at the toe of the dam is not considered to be significant at this time; however, the condition should be monitored to document if seepage is developing.

This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Sophia Dam consists of an earth embankment approximately 340 feet long with a maximum height of 29 feet from the downstream toe and a crest width of 9 feet. The upstream side of the dam is protected by a small amount of riprap and the downstream face is covered with grass. The flood discharge facilities for the dam consist of a concrete open-channel spillway located near the left abutment. The outlet facilities consist of a 12-inch-diamenter corrugated metal pipe extending through the embankment along the original streambed. Based on the evaluation of existing conditions, the condition of Lake Sophia Dam is considered to be unsafe/nonemergency due to seriously inadequate spillway capacity. The flood discharge capacity was evaluated according to to the recommended procedure and was found to pass approximately 15 percent of the PMF without overtopping the dam. Results of the breach analysis indicate that downstream damage would be significantly increased due to a dam failure.

This book was released on 1981 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction data indicate that Longford Lake Dam is in good condition. In accordance with the guidance provided, the spillway design flood (SDF) ranges between 1/2 the PMF and the full PMF. Based on the size and extent of downstream hazard for the dam, the SDF selected for this facility was the PMF. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass 88% of the PMF prior to overtopping the embankment. Therefore, in accordance with the recommended criteria for Phase I inspections, the spillway for Longford Lake Dam is considered to be inadequate.

Jeffrey Kimball and published by . This book was released on 1979 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Mount Union Dam is a concrete buttress dam. Lake Mount Union Dam was built by the Ambursen Construction Company and is thus called an Ambursen type dam. Ambursen dams are articulated, reinforced concrete buttress dams with expansion joints between the decks and the buttresses. The deck consists of reinforced concrete water bearing slabs, separated by buttress tongues and supported by reinforced concrete haunches which are constructed monolithically with the buttresses. Lake Mount Union Dam has seventeen vertical concrete buttresses constructed on eighteen foot centers. These buttresses are founded on shale and quartzite. The buttresses are of variable thickness with the bottom of each buttress 21 inches thick and the top of the buttress 14 inches thick. The concrete slab on the upstream of each buttress is also of variable thickness. The bottom of the slab is 41.5 inches thick with the top of the slab 24 inches thick. The concrete slab is sloped at an angle of 1H:1V. At the toe of the upstream slope of the dam a cutoff trench was excavated. This cutoff trench was backfilled with concrete. Steel reinforcing was placed in all buttresses and throughout the concrete slab. Between all expansion joints, asphalt putty was placed.

This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Pioneer Lake Dam is based upon visual observations made at the time of inspection, review of available records and data, hydraulic and hydrologic computations and past operational performance. The dam and appurtenant structures appear to be in fair condition. No major erosion was observed on the embankment crest. An erosion area was observed at the outlet for the 12 in. diameter cast iron pipe. Erosion at the outlet of the 12 in. diameter pipe exists on the downstream slope of the dam near the toe. Seepage 100 ft. right of the spillway channel was measured to be approximately 50 gallons per minute. A 30 in. corrugated metal pipe exists beneath the roadway near the outlet for the emergency spillway. It was observed during the inspection that the pipe is collapsing near the center of the pipe. Trees were observed growing along the upstream edge of the crest, and dense vegetation was observed along the entire length of the downstream slope. The Pioneer Lake Dam is a high hazard-small size dam. The recommended spillway design flood (SDF) for a dam of this size and classification is in the range of the 1/2 PMF to PMF. Due to the downstream potential for loss of life and property damage, the spillway design flood has been selected as the PMF. The spillway and reservoir are capable of controlling approximately 11% of the PMF without overtopping the embankment. Based on criteria established by the Corps of Engineers, the spillway is termed seriously inadequate. Pioneer Lake Dam is classified as unsafe, non-emergency.

This book was released on 1979 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recreation Dam is an L-shaped earth dam with a measured maximum height of 14.7 feet and a total length of approximately 1,600 feet. The facility is provided with a masonry spillway at the left abutment along its northern section and a diversion canal along its easterly extension. The latter serves to divert acid mine drainage from upstream mined areas around the facility. Based on visual observations, past history, and a hydrologic and hydraulic investigation, the dam and its appurtenances are considered in poor condition. Based on a visual evaluation and past performance the spillway system is considered structurally unsafe but of non-emergency status as the reservoir is completely drawn down. In addition, evaluation of the flashboard system indicated that failure of the flashboards under normal operating procedures could in itself cause serious downstream consequences.
