This book was released on 1981 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, Acre Pond Dam is judged to be in fair structural condition. In the absence of an adequate spillway, the dam is subject to frequent overtopping. Based on the location of the downstream dwellings and the fact that a few lives could be lost should the dam fail, the dam is classified as a significant hazard dam. Since the spillway cannot pass the 100- year flood without overtopping the dam, the spillway is rated as inadequate. Although there is some seepage thru the dam, there is no evidence of structural instability. There is no formal inspection and maintenance program or warning system and evacuation plan in effect at Acre Pond Dam. The dam is not properly maintained.

Dziubek and published by . This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hathaway Pond Dam is located in Ararat Township, Susquehanna County, Pennsylvania. The reservoir was originally created to provide water for power purposes. The reservoir slopes are moderate with a good cover of vegetation. There are three ponds upstream from Hathaway Pond Dam on two tributary streams. The western stream contains Romobe Lake (PennDER I.D. No. 58-10) which is 1750 feet upstream from Hathaway Pond Dam. The eastern tributary contains Ball Lake and an unnamed smaller pond in series. Ball Lake is 2450 feet upstream and will retain considerable storage while the smaller unnamed pond was considered to have no effect on Hathaway Pond Dam. Two homes, a trailer, and township road are located 1800 feet downstream from Hathaway Pond Dam. These could suffer economic damage in the event of a dam failure.

Jeffrey Kimball and published by . This book was released on 1981 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is located approximately 2 miles northwest of the Village of Colley, Wilmot Township, Bradford County, Pennsylvania. The inspection consisted of: Visual inspection of the retaining structure, abutments and toe; Examination of the spillway facilities, exposed portion of any outlet works and other appurtenant works; Observations affecting the runoff potential of the drainage basin; and Evaluation of the downstream area hazard potential. The dam appears to be in good condition and adequately maintained. From a brief survey conducted during the inspection, it was noted that the low spot on the crest of the dam exits at the top left edge of the spillway crest. It was observed during the inspection that a new concrete cap had been placed on the structure. The concrete appeared to be in good condition. The dam was constructed with dry rubble masonry with an upstream earthfill. No concrete exists on the downstream face of the structure or on the bench located along the downstream face of the structure. The rubble masonry appeared to be in good condition and well maintained.

This book was released on 1979 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam consists of a zoned, earthfill embankment that is 590 feet long and 52 feet high at its maximum section. The main spillway is a drop spillway located near the right abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. The auxiliary spillway is an excavated channel along the left abutment of the dam. It is a grass-linked excavation in earth. Based on visual inspection, available records, calculations and past operational performance, PA-467 Dam is judged to be in good condition. The existing spillway can pass the Probable Maximum Flood(PMF) without overtopping of the dam. The spillway capacity is rated as adequate. There is a slope stability analysis for the embankment, and it indicates that the embankment has adequate factors of safety. There is no evidence of significant problems threatening the embankment.

This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Cooks Pond Dam is considered to be unsafe/nonemergency due to the seriously inadequate spillway capacity and structural deficiencies. The condition of the embankment is considered to be poor. The dam is old and in a general state of disrepair. The crest of the dam is irregular and the center of the dam appears to have settled. The stone wall along the downstream toe is irregular and bulging. The toe of the wall is swampy, caused by a general underseepage. In view of these observations, the overall stability of the dam is considered to be questionable, requiring further investigation and implementation of measures to improve the stability of the dam. The spillway capacity was evaluated according to the recommended procedure and was found to pass less than 10 percent of the Probable Maximum Flood (PMF) without overtopping the embankment. This capacity is less than the required spillway capacity of one-half PMF relative to the size and hazard classification of the dam. Because the spillway capacity is less than 50 percent of the PMF and it is estimated that failure of the dam due to overtopping would significantly increase the downstream hazard of loss of life compared to that which would exist just before failure, the spillway is considered to be seriously inadequate, and consequently the condition of the dam is considered to be unsafe/nonemergency.

This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Lake Dam is located on Forest Lake Creek in Forest Lake Township, Susquehanna County, Pennsylvania. The original purpose of the impounded water was for ice harvesting and recreation. Additionally, water releases from the impoundment activated a saw mill. Presently, the lake is being used for recreation. The overall appearance of the dam is poor. Location of observed deficiencies are shown on the General Plan. The profile and typical sections of the dam are presented and are based on field survey made on the day of inspection. The survey datum for this inspection is elevation 1527 feet above mean sea level which is stamped on the USGS Bench Mark (No. TT15K, 1931) on the large sandstone slab, upstream of the service spillway. On the inspection date (12/10/1980), the lake was being drawn down for the winter. The lake level was approximately at elevation 1523.6, or 2.8 feet below its normal level. Deficiencies observed during the field inspection are described. Visible features are depicted in photographs.

This book was released on 1981 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available data indicate that Duck Pond Dam is in fair condition. The lack of embankment protection from spillway flows and the inadequate spillway capacity are the primary deficiencies which cause concern for the safety of this dam. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for this facility is in the range of the 100 year flood to 1/2 the Probable Maximum Flood (PMF). Based on the size of the dam and degree of downstream hazard, the selected SDF is the 100 year flood. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and outlet works discharge capacity will not pass the SDF (100 year flood) prior to overtopping the embankment. In accordance with the criteria outlined and evaluated in Section 5.5 of this report, the discharge capacity for Duck Pond Dam is considered to be inadequate.

This book was released on 1981 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Sharpe's Pond Dam is considered to be fair. No conditions were noted that would significantly affect the structural stability of the dam. The formal spillway facility, which consists of a three-foot-diameter drop inlet pipe, is considered to be vulnerable to blockage by debris during a flood and is, therefore, considered inadequate. Although a low area exists over the left abutment which may function as an emergency spillway, a need exists for the installation of a formal emergency spillway facility. Flood discharge capacity of the dam, including the flow over the left abutment, was evaluated according to the recommended procedure and was found to be approximately 10 percent of the Probable Maximum Flood (PMF) without overtopping the low spot on the main embankment. This capacity is less than the recommended one-half of the PMF, according to the size and hazard classification for the dam. Although the spillway capacity is less than 50 percent of the PMF, overtopping of the dam is not considered to constitute a major breach potential. Therefore, the spillway is classified to be inadequate, but not seriously inadequate.

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 1979 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection is to determine if the dam constitutes a hazard to human life or property. The dam consists of a homogeneous earthfill embankment that is 680 feet long and 64 feet high at its maximum section. The main spillway is a drop spillway located near the left abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. One 12-inch by 21-inch uncontrolled orifice is located in the upstream face of the concrete riser with the orifice crest at El. 1227.0, which is 27 feet below design elevation of the top of the dam. The auxiliary spillway is an excavated channel at the right abutment of the dam. It is grass-lined except for portions that were excavated into rock. The hazard classification is high hazard. Downstream conditions indicate that a high hazard classification is warranted for PA-468 Dam. It is owned by the Susquehanna County Commissioners. Its purpose is for flood control.

Book excerpt: Harris Pond Dam is a combination earth, concrete and masonry structure approximately 10 feet high and 135 feet long, including spillway. It is located on Roaring Brook Creek in Ross Township, Luzerne County, Pennsylvania. The overall appearance of the facility suggests it to be in good condition. The only deficiency noted by the inspection team that requires immediate remedial attention was the areas exhibiting concrete deterioration. Flashboards (reportedly removed during significant storms) were observed in-place across the service spillway. Although generally considered undesirable, they appear, in this particular case, to be of little significance relative to the safe operation of Harris Pond Dam.

Andersen and published by . This book was released on 1981 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Chamberlain Pond Dam is considered to be unsafe/nonemergency because of structural deficiencies and seriously inadequate flood discharge capacity. The dam is a dry masonry wall backed by an earth fill. The left abutment nonoverflow section appears to have settled, causing structural cracks in the dam. The stone wall on the downstream side of this section is bulging and tilting downstream. In view of these conditions, the structural stability of the dam is considered to be questionable, requiring further investigation. The flood discharge capacity of the dam was evaluated according to the recommended criteria and it was found to pass approximately 20 percent of the Probable Maximum Flood (PMF) without overtopping the nonoverflow section of the dam. This capacity is less than the recommended spillway design flood of full PMF. Because the dam cannot pass 50 percent of the PMF and because failure of the dam is considered to significantly increase the downstream damage potential compared to that which would exist just before failure, the flood discharge capacity of the dam is considered to be seriously inadequate.

This book was released on 1981 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Negro Pond Dam is considered to be poor. The dam essentially consists of a mound of stones. It appears that originally it was a dry stone wall backed by an earth fill. As it exists, flow from the reservoir partially flows over a low section on the dam and partially percolates through the rubble to the downstream toe. The dam has no formal spillway facilities. Therefore, the flood discharge capacity of the dam is considered to be inadequate. A breach analysis indicated that failure of the dam during the passage of 50 percent PMF is likely to endanger the stability of a downstream dam and the combined discharge may cause loss of life and property damage. Consequently, the flood discharge capacity of the dam is considered to be seriously inadequate and the facility is classified to be unsafe/nonemergency.

This book was released on 1979 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryant Pond Dam is an earthfill and rockfill dam with a concrete core-wall. The earthfill extends along the upstream side of the core-wall and the rockfill extends along the downstream side. The dam, including the main and auxiliary spillways, is 425 feet long. The design height is 19 feet. The main spillway is located near the left abutment of the dam. It is a series of concrete slabs forming a cascade to the natural stream. Other than its exterior lines and grades, details of the main spillway are unknown. The main spillway crest is 40 feet long and 5 feet below the design top of the dam. The auxiliary spillway was designed to be a 175-foot long by 2-foot deep notch in the concrete core-wall. It was constructed 200 feet long. The auxiliary spillway was designed to allow water to flow over the rockfill on the downstream slope of the embankment. The outlet works is located directly to the right of the main spillway. It consists of two 2-foot square concrete conduits with concrete sluice gates at the upstream end. The various features of the dam, as designed, are shown on the Plates at the end of the report. The existing features are shown in Appendix D. (Author).

This book was released on 1980 with total page 106 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 structure is one-half the PMF. The spillway capacity is adequate for passing only 10 percent of the PMF peak inflow without overtopping the dam. The spillway is considered to be seriously inadequate. The dam is therefore unsafe, non-emergency.
