This book was released on 1981 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The condition of Bel-Air Lake Dam is considered to be unsafe/ nonemergency due to a seriously inadequate spillway capacity. The overall condition of the dam is considered to be fair. Although at this time no signs of significant distress were observed, it appears that the center of the dam has significantly settled. The design drawings show the design freeboard to be five feet, but the available freeboard is only approximately two feet. It also appears that fill has been placed on the downstream slope, increasing the crest width from the design value of 10 feet to about 30 feet near the center line of the dam and greater than 50 feet near the left abutment. The dam has no functional low level outlet facility.

Michalcin and published by . This book was released on 1980 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a visual inspection, operational history, and available engineering data, the facility is considered to be in good condition. The size classification of the facility is intermediate and its hazard classification is considered to be high. In accordance with the recommended guidelines, the Spillway Design Flood (SDF) for the facility is the PMF (Probable Maximum Flood). Results of the hydrologic and hydraulic analysis indicate the facility will pass and/or store only about 45 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. Calculations also indicate that if the spillway were constructed in accordance with available desing drawings, the facility could pass and/or store approximately 63 percent of the PMF.

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.

Dziubek and published by . This book was released on 1981 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Warner Dam is owned by William S. Newlin, Jr., and is classified as a 'Low' hazard - 'Small' size dam. The dam was found to be in fair overall condition at the time of inspection. Hydraulic/hydrologic evaluations revealed that the spillway capacity is less than the peak inflow to the impoundment during the 100-year flood. A spillway design flood (SDF) in the range of the 50- year flood to the 100-year flood is required for Warner Dam. The 100-year flood was chosen as the SDF. The spillway is therefore considered 'Inadequate.' It is recommended that the owner immediately develop remedial measures to provide adequate spillway capacity. The inspection revealed certain items of remedial work which should be performed by the owner without delay. These include: (1) Provide adequate spillway capacity; (2) Repair the spalling on the downstream face of the concrete corewall; (3) Ensure that the outlet works are operable, or develop an emergency drawdown plan; and (4) Cut all trees on the embankment at ground level. All trees with a trunk diameter greater than 3 inches should have their root systems removed. All resultant areas of erosion and cavities should be filled, graded, compacted and seeded. In addition, the following operational measures are recommended to be undertaken by the owner: (1) Develop a detailed emergency operation and warning system; (2) During periods of unusually heavy rainfall, provide around-the-clock surveillance of the dam; and (3) When warning of a storm of major proportions is given by the National Weather Service, activate the emergency operation and warning system.

This book was released on 1981 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The visual inspection and review of available design and construction data indicate the Valley View Lake Dam is in poor condition. The deteriorated condition of the spillway walls, severe erosion of the spillway discharge channel, and seepage observed at the downstream toe are the primary deficiencies which cause concern for the safety of this facility. The dam in its present condition is considered to be unsafe, non-emergency. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and spillway discharge capacity will pass only 32% of the PMF prior to overtopping the embankment. Overtopping the dam could cause failure, which would lead to a significant increase in downstream loss of life and property damage. Therefore, the spillway for Valley View Lake Dam is considered to be seriously inadequate. Measures recommended for immediate action are listed.

This book was released on 1981 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the evaluation of the existing conditions, the condition of Tuscarora Lake Dam is considered to be fair. Although some deficiencies were observed such as seepage from the toe and lack of upstream erosion protection, none were considered to be significant relative to the overall stability of the dam at this time. Periodic inspection and evaluation of the seepage conditions are recommended. It was found that the dam has no now level outlet facilities. The flood discharge capacity of the dam was evaluated according to the recommended criteria and the spillway was found to pass 10 percent of the PMF without overtopping the low spot of the embankment. This capacity is less than the recommended spillway capacity of 50 percent of the PMF which was based on the size and downstream hazard classification of the dam. Therefore, the spillway capacity is classified to be inadequate.

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 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment of Brown's Lake Dam is based upon visual observations made at the time of inspection, hydraulic and hydrologic computations and past operational performance. The inspection and review of data of the Brown's Lake Dam did not reveal any problems which would require emergency action. The dam appears to be in good condition and adequately maintained. Brown's Lake Dam is a high hazard-small size dam. The spillway design flood (SDF) for a dam of this size and classification is 1/2 PMF to the PMF. the PMF has been selected as the spillway design flood based on downstream potential for loss of life. The spillway and reservoir are capable of controlling the spillway design flood (PMF). Based on criteria established by the Corps of Engineers, the spillway is termed adequate. The following recommendations and remedial measures should be instituted as soon as possible. (1) A regularly scheduled maintenance program should be developed and implemented. (2) A warning system should be developed to warn downstream residents of large spillway discharges or imminent failure of the dam. (3) A safety inspection program should be implemented with inspections at regular intervals by qualified personnel. (4) The drainline valve should be operated on a regular basis.

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.
