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.

Delaware River Basin, Branch of Hornbecks Creek, Pike County, Pennsylvania. Phase I Inspection Report written by Bernard M. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Lower Lake Dam is an earth embankment with a concrete gravity spillway. The embankment is approximately 340 feet in length with a maximum height of 22.5 feet. The dam inpounds a reservoir with a surface area of 250 acres and a storage capacity of 1,085 acre-feet at normal pool level. The top of the dam is 20 feet wide; the upstream and downstream side slopes are approximately 2.5 horizontal to 1.0 vertical (2.5H:1V). No information is available concerning the properties of the embankment materials. Within the embankment is a tapered reinforced concrete cutoff wall that extends from bedrock to 3.5 feet below the top of the embankment. The reinforced concrete spillway, which has maximum height of 13 feet from base to crest, consists of 3 sections separated by bridge piers. Each section id broad-crested weir with a vertical upstream face and a flat, sloping downstream face. The crest of the center section is 48.5 feet long and crest of each of the two end sections is 45.75 feet long. The crest of the center section, which is 3 feet wide, is 0.5 feet below the crest of the end sections; each of the end sections is 2.5 feet wide.

Phase I Inspection Report written by O'BRIEN AND GERE ENGINEERS INC PHILADELPHIA PA JUSTIN AND COURTNEY DIV. and published by . This book was released on 1979 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemlock Lake Dam is an earth embankment with a concrete core wall. The embankment is about 625 feet long with a maximum height of approximately 14 feet. The top width of the dam is a minimum of 150 feet and the earth embankment side slopes are 3 horizontal to 1 vertical (3H:1V) both upstream and downstream. The top of the dam is used as a golf course fairway. A drop spillway, with a round crested weir, is located adjacent to the right (looking downstream) abutment. The crest of the weir is 3 feet below the top of the dam, and the length of the weir is 47 feet. The drop spillway is of stone masonry construction except for the rounded weir crest section which is poured concrete. The distance from the drop spillway weir crest to the apron is about 7 feet. The apron is 20 feet long and slopes down from each side wall. The transverse end sill is of negligible height at the side walls and is about 2 feet high in the center. Two 24-inch semi-circular corrugated steel pipes are constructed into the end sill and act as control structures. Flow passes over the drop spillway, through the two corrugated pipes, and into Lower Lake.

Phase I Inspection Report written by Hendrik Jongsma and published by . This book was released on 1980 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in fair condition. In accordance with the Corps of Engineers' evaluation guidelines, the size classification of this dam is small and the hazard classification is high. These classifications indicate that the Spillway Design Flood (SDF) should be in the range of one-half the Probable Maximum Flood (PMF) to the full PMF. The recommended SDF for this flood control structure is the PMF. The spillway capacity is adequate for passing 71 percent of the PMF peak inflow without overtopping the dam. The spillway, therefore, is considered to be inadequate, but not seriously inadequate.

This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: North Lake Dam is located on a branch of Hornbecks Creek in Delaware Township, Pike County, Pennsylvania. The facility is located approximately 1,500 feet upstream and west of wild Acres Lake, and about five miles from U.S. Route 209 which parallels the Delaware River in this area. Observations made during the visual inspection indicate the embankment is in fair condition, but in need of general maintenance. No evidence of seepage through the downstream embankment face, sloughing, erosion or animal burrows was observed. The embankment crest is noticeably low (in excess of 1-foot) near the spillway relative to the remainder of the crest. About two-thirds of the embankment is overgrown along an area extending approximately 400 feet to the right of the spillway. The vegetation is characterized as primarily brush and high weeds with clumps of small trees strewn throughout. In contrast, much of the embankment crest and upstream face are bare and unprotected with only light vegetation visible. Several long tire ruts scar the crest near the spillway. A small area characterized by swamplike vegetation is located about 350 to 375 feet from the right abutment along the downstream embankment toe. Seepage was observed at the downstream embankment toe near the outlet conduit flowing at a rate of about two to three gpm. The flow is suspected of being either seepage through the embankment foundation, or perhaps drainage from a concealed toe drain. A precise assessment of the condition is difficult without adequate design data are drawings.

This book was released on 1981 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild Acres Lake Dam is located on a branch of Hornbecks Creek in Delaware Township, Pike County, Pennsylvania. The facility is an integral part of the surrounding development known as Wild Acres. The community is nestled in the mountains of Pike County less than five miles west of U.S. Route 209 which parallels the Delaware River in this area. Observations made during the visual inspection indicate the embankment and adjacent dike are in good condition. Heavy brush growth and small trees were observed along the embankment crest and upstream face. No evidence of seepage through the downstream embankment face, excess settlement, sloughing, erosion or animal burrows was encountered by the inspection team. Some rock slope protection has been displaced immediately adjacent the spillway right wingwall, leaving small bare areas on both the upstream and downstream embankment faces. The top of the concrete corewall exhibits excessive cracking and spalling along its entire length except for that portion associated with the dike along the right abutment which is in relatively good condition.

Pine Ridge Community Association. Phase I Inspection Report written by Frederick Futchko and published by . This book was released on 1980 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maple Lake Dam is a homogeneous, earthfill embankment. It is 35 feet high at its maximum section and 685 feet long. The main spillway is located at the maximum section of the dam. It consists of a reinforced concrete riser structure near the upstream toe of the dam, a 24-inch diameter conduit, and a concrete outlet structure at the downstream toe of the dam. The auxiliary spillway is an excavated, trapezoidal channel at the left abutment of the dam. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Maple Lake Dam is judged to be in good condition. Based on existing conditions, the main and auxiliary spillways will pass an approximate minimum of 48 percent of the Probable Maximum Flood (PMF before overtopping of the dam occurs. No stability problems were evident for the embankment at the time of the visual inspection, but a potential hazard to stability exists due to erosion that might occur when there is flow in the auxiliary spillway.

This book was released on 1981 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose is to determine if the dam constitutes a hazard to human life or property. Beaver Lake Lodge Dam is located on Raymondskill Creek in Milford Township, Pike County, Pennsylvania. The visual inspection of the facility suggested that the dam and its appurtenances are in poor condition. The overall appearance of the facility suggests it to be in poor condition. Remedial measures are necessary to: (1) repair to deteriorated concrete spillways, (2) remove the trees and overgrowth from the embankment crest and slopes, (3) provide adequate erosion protection along the downstream embankment toe, and (4) restore the operability of the outlet conduit, or provide an alternate means of reservoir drawdown.

Available in PDF, EPUB and Kindle. Book excerpt: Taylor Pond Dam is a zoned earth and rockfill embankment, approximately 2,300 feet in length with a maximum height of 76 feet. The embankment is constructed with a change in alignment (78 degree bend) to the right, starting approximately 1,100 feet from the left abutment. The top of the dam is 22 feet wide at design Elevation 1829. The embankment side slopes are 2 horizontal to 1 vertical (2H:1V) both upstream and downstream. According to the as-built plans, the embankment is constructed in three zones. A central impervious core to Elevation 1821 and a cutoff trench extending to 22 feet below natural ground are composed of silt (ML) and clay (CL) materials (Zone 1). The core side slopes are 0.4H:1V and the top width is 10 feet. The cutoff trench has 1H1V side slopes and a 10 foot bottom width. Zone 2 material is an intermediate layer between the core and the shell and consists of silty sand (SM), silty gravel (GM), and cobbles from the designed borrow areas. Zone 2 extends to Elevation 1827 with a top width of 20 feet and side slopes which are slightly steeper than 2H:1V. Zone 3 material, which forms the upstream and downstream shells, is composed of rocks larger than 6 inches obtained from the Emergency Spillway excavation and oversize material raked out of Zone 1 and Zone 2 material.
