McDermott and published by . This book was released on 1981 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is an earth embankment supporting Gloucester County Highway Route 635 known as Lambs Road. The spillway structure consists of a horseshoe-shaped concrete weir located on the upstream side of the embankment. At the center of the embankment a concrete bridge forms the spillway discharge channel. The outlet works consists of a gated 2' x 2.5' sluice which transversely penetrates the center of the concrete spillway structure. The outlet discharges from the downstream face of the spillway structure into a stilling area between the spillway and bridge. Based on visual inspection, past operational performance and Phase I engineering analyses, Bethel Lake Dam is assessed as being in fair overall condition. Hydraulic and hydrologic analyses indicate that the spillway is inadequate. Discharge capacity of the spillway is not sufficient to pass the designated spillway design flood (100-year storm) without an overtopping of the dam. The spillway is capable of passing approximately 14 percent of the SDF.

Keith Jolls and published by . This book was released on 1979 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on visual inspection, available records, calculations and past operational performance, Lake Wadsworth Dam, a high hazard potential structure, is judged to be in fair overall condition. The dam's spillway is considered inadequate since 12 percent of the Spillway Design Flood--SDF - would overtop the dam. (The SDF, in this instance, is one half of the Probable Maximum Flood). The decision to consider the spillway 'inadequate' instead of 'seriously inadequate' is based on the determination that dam failure resulting from overtopping would not significantly increase the hazard to loss of life downstream from the dam from that which would exist just before overtopping failure. Recommended actions are made to insure adequacy of the structure.

This book was released on 1981 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alcyon Lake Dam is located in the Borough of Pitman, Gloucester County, New Jersey. Visual inspections were conducted on December 4, 1979 and January 10, 1980 at which time a stable reservoir condition was maintained. The tops of the flashboards at the main spillway and the stoplags at the auxiliary penstock inlet are at roughly the same elevation and were discharging about 2 inches of flow.

Keith Jolls and published by . This book was released on 1979 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sterling Lake Dam is an ill-defined 150 foot long highway embankment structure with a bridged spillway. The spillway is a concrete arch weir 22 feet in length with a 2 foot x 2 foot wood gate in the center of the arch. Gloucester County Bridge No. 5-J-14 spans the 16 foot discharge opening. The two-lane asphalt Pitman-Downer Road (30 feet in width) runs along the dam crest. At the upstream face of the embankment are situated 3 foot high dikes with stone masonry walls keyed into the earth and supporting remnants of a boardwalk. The slopes of the downstream embankment vary between 1H:1V at the outlet to 3H:1V near the abutments. Sterling Lake Dam is assessed to be in a fair overall condition although the spillway should be further inspected and additional hydrological/hydraulic studies undertaken to ascertain what improvements can be made in view of the fact that the discharge culvert is almost completely submerged by the downstream lake. The capacity of the spillway will accommodate only 6% of the 1/2 PMF design flood but the dam is not assessed as UNSAFE, NON-EMERGENCY as collapse from overtopping could not increase the hazard to life downstream from the erstwhile condition prior to overtopping.

Keith Jolls and published by . This book was released on 1979 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is a 55 year-old earth embankment approximately 120 feet in length with a bridged spillway. An asphalt pavement (Elmer-Barnsboro Rd.) 30 feet in width runs along the crest. The spillway is a three sided concrete drop inlet with removable 3 in.-6 in. wide timber stoplogs on the front face. Steel sheet piling extends along the shoulder line on the upstream face of the dam on each side of the drop inlet. The maximum height of the dam is 13 feet at the culvert outlet. Wrights Mill Dam is assessed to be in a good overall condition and no physically detrimental conditions were observed but further hydraulic studies are recommended in the future to ascertain more accurately the capacity of the spillway. Overtopping of the dam could lead to a downstream embankment washout. Remedial actions recommended to be undertaken in the near future include (1) remove the dead trees and root systems on the downstream embankment slopes, (2) place riprap in the downstream channel and (3) place slope protection at the ends of the steel sheeting and downstream culvert wingwalls. The capacity of the spillway will accommodate only 24% of the one-half PMF design flood.
