National Dam Inspection Program. Little Youghiogheny River Site Number 5 (NDI-ID-MD-55), Ohio River Basin, Landon's Dam Run, Garrett County, Maryland. Phase I Inspection Report,

Abstract

The Little Youghiogheny Site No. 5 dam was designed as a zoned earthfill structure. The dam is approximately 550 ft. long, has a maximum toe-to-crest height of 41 ft., and a crest width of 15 ft. Upstream and downstream embankment slopes have inclinations of 3H:1V and 2.5H:1V, respectively. An earthfill cutoff trench is located on the centerline of the embankment and extends the full length of the dam. According to as-built drawings, seepage water is collected by a sand and gravel filter trench and perforated pipe drain system. This drain system is located approximately 45 ft. upstream from the downstream embankment toe and is extended about 8 ft. below the original ground elevation. Collected seepage is drained out of the dam embankment by means of a sand and gravel blanket drain and two non-perforated outlet drain pipes located near the reinforced concrete pipe outlet.
