National Dam Inspection Program. Little Youghiogheny River Site Number 7 (NDI-ID-MD-32), Ohio River Basin, Main Branch of the Little Youghiogheny River, Garrett County, Maryland. Phase I Inspection Report
Little Youghiogheny Site No. 7 consists of an earthfill embankment approximately 700 ft. long, with a maximum toe to crest height of 45 ft. and a crest width of 16 ft. The upstream embankment slope is inclined 4H:1V between the embankment toe and berm located at normal pool level, and 3H:1V between the berm and dam crest. The downstream embankment slope is inclined 2.5H:1V, and has a 10 ft. wide berm located 25 ft. below the top of the dam. Seepage control provisions consist of a filter trench collector system and a blanket drain and corrugated metal pipe outlet system. Filter trench extensions are located about 90 ft. upstream from the downstream embankment toe and are extended a maximum of 14 ft. below original ground. Collected seepage water is discharged into the outlet plunge pool. Flood discharge facilities consist of a principal spillway riser, located 325 ft. from the north abutment, and an emergency spillway channel located on the south abutment.
