National Dam Inspection Program. Lake Somerset Dam (NDS I.D. Number PA-00229, PennDer I.D. Number 56-89), Ohio River Basin, East Branch of Coxes Creek, Somerset County, Pennsylvania. Phase I Inspection Report,

Abstract

Based on the visual inspection, operational history, and available engineering data, the dam, despite being well maintained, is considered to be in poor condition. Observations made during the visual inspection suggest that the embankment may be structurally unsafe as extensive areas of seepage were noted on the downstream embankment slope and immediately below the toe area to the right of the outlet conduit. Seepage conditions became evident shortly after reservoir filling and have persisted in spite of the installation of a remedial sand drain system near the toe. Failure of the embankment does not appear imminent and the condition is presently considered non-emergency. It is recommended that the owner immediately develop and implement a warning system to notify downstream inhabitants should hazardous conditions develop. Included in the plan should be provisions for around-the-clock surveillance of the facility during periods of unusually heavy precipitation.
