Phase I Inspection Report written by Lawrence D. 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.

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . 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.

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . 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.

Phase I Inspection Report written by Lawrence D. Anderson and published by . This book was released on 1981 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Jennings Pond Dam is considered to be fair. The dam is a dry masonry structure backed by an earth fill on the upstream side. Although the conditions observed are not significantly affecting the overall performance of the dam at this time, the apparent downstream creeping of the dam suggests that the continued stability of the dam is questionable. Further, due to the lack of erosion protection at the abutment and downstream of the nonoverflow sections, significant overtopping of the nonoverflow sections may result in major damage to the dam. Further evaluation of these concerns by a professional engineer is recommended. The flood discharge capacity of the dam was evaluated according to the recommended procedure and was found to pass approximately 10 percent of the Probable Maximum Flood (PMF) without overtopping the nonoverflow sections of the dam. This capacity is less than the recommended spillway design flood of 50 percent of the PMF. Therefore, the spillway capacity is classified to be inadequate.

Download or read book National Dam Inspection Program. Perrins Marsh Dam (NDI I.D. PA-0886, DER I.D. 066-005), Susquehanna River Basin Whitelock Creek, Wyoming County, Pennsylvania. Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1981 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perrins Marsh Dam, which is also known as Brown's Pond Dam or Schoonover's Lake, consists of a six-foot-high stone wall, backed by earth fill on the upstream side. In its present configuration, the dam appears to be about 50 to 60 feet long, with a 28-foot-long segment forming the overflow section of the dam. The overflow section is capped with a six-foot-wide concrete slab which appears to be about one foot thick. The earth fills flanking the overflow section gradually merge into the natural abutments with no discernible embankment-abutment junction. The dam does not appear to have any low level outlet facilities. It appears that this dam was constructed at the outlet of a natural lake to raise the lake level. The dam is classified to be in the significant hazard category. Below the dam, Whitelock Creek flows about 150 feet, falls over a stone wall, then flows under a bridge. A house located downstream of the bridge is considered to be in the floodplain of the creek. The stream flows adjacent to a rural residential area for approximately one mile, and then discharges to an essentially uninhabited valley. It is estimated that a failure of this dam would likely cause damage to the downstream bridges and property in the rural residential area. Loss of a few lives is considered possible.

Phase I Inspection Report written by R. 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.

Download or read book National Dam Inspection Program (NDI ID Number PA-00893, DER ID Number 66-35), Winola Mill Pond Dam, Susquehanna River Basin, Tributary to Beaver Creek, Wyoming County, Pennsylvania. Phase I Inspection Report written by Frederick Futchko and published by . This book was released on 1979 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, and according to criteria established for these studies, Winola Mill Pond Dam is judged to be unsafe, nonemergency, because the spillway capacity is rated as seriously inadequate. The existing walls of the main spillway will overtop at about 6 percent of the Probable Maximum Flood(PMF). Overtopping of the walls will cause erosion of the dry masonry section of the dam. It is estimated that the 15 percent PMF would cause sufficient erosion to cause the dam to fail. The initial surge from the failure of the dam would increase the hazard to loss of life downstream. As a whole, the dam is judged to be in fair condition. Cracks have developed in the concrete liner wall on the upstream face of the dry masonry. Excessive leakage and a hole in the upstream earthfill had previously developed and the repairs made to the structure do not eliminate the possibility of these conditions reoccurring. Although a preliminary stability analysis indicates no apparent need for immediate concern, the theoretical stability of Winola Mill Pond Dam is unknown because the foundation conditions are unknown.

This book was released on 1981 with total page 72 pages. Available in PDF, EPUB and Kindle. 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.

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.

Download or read book National Dam Inspection Program. Acre Pond Dam (NDI ID Number PA-00973, DER ID Number 58-34), Susquehanna River Basin, Partners Creek, Susquehanna County, Pennsylvania. Phase I Inspection Report written by and published by . 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.

Phase I Inspection Report written by D'APPOLONIA CONSULTING ENGINEERS INC PITTSBURGH PA. and published by . 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.

Phase I Inspection Report written by GANNETT FLEMING CORDDRY AND CARPENTER INC HARRISBURG PA. and published by . This book was released on 1979 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marshwood Dam is two homogeneous earthfill embankments with masonry core-walls. The dam was built in a natural saddle. The embankments impound water within the saddle. The dam has a main spillway and an auxiliary spillway. The main spillway is located at the right abutment of the South Embankment. It has a sharp-crested concrete weir with a crest length of 100 feet. The auxiliary spillway is a canal about 300 feet left of the South Embankment. Based on visual inspection, available records, calculations and past operational performance, Marshwood Dam is judged to be in fair condition. The spillway can pass 65 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. The spillway capacity is rated as inadequate. This rating is dependent on implementation of some of the recommendations herein. If the low areas on the embankments were raised 0.6 foot to the design elevation, the spillway can pass 80 percent of the PMF. The spillway capacity would still be rated as inadequate.

Phase I Inspection Report written by Lawrence D. Andersen and published by . This book was released on 1981 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of a Phase I investigation is to identify expeditiously those dams which may pose hazards to human life or property. The assessment of the general condition of the dam is based upon visual observations and review of available data. Detailed investigations and analyses involving topographic mapping, subsurface investigations, material testing, and detailed computational evaluations are beyond the scope of a Phase I investigation; however, the inspection is intended to identify any need for such studies which should be performed by the owner. In reviewing this report, it should be realized that the reported condition of the dam is based on observations of field conditions at the time of inspection along with data available to the inspection team. In cases where the reservoir was lowered or drained prior to inspection, such action, while improving the stability of the dam, removes the normal load on the structure and may obscure certain conditions which might otherwise be detectable if inspected under the normal operating environment of the structure.

Phase I Inspection Report written by John A. 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.
