National Dam Inspection Program. Little Youghiogheny River Site Number 2. (NDI I.D. Number MD-33) Ohio River Basin. Cherry Glade Run, Garrett County Maryland. Phase I Inspection Report
Based on the evaluation of available design information, and visual observations of conditions as they existed on the dates of the field reconnaissances, the general condition of Little Youghiogheny Site No. 2 is considered to be good. Seepage, observed emanating from the left (east) stream bank of the outlet plunge pool, should be monitored for increases in flow or areal extent, and for development of internal erosion conditions. Measurements should be made to determine if seepage flow is affected by changes in reservoir pool level or seasonal fluctuations in ground water conditions. The wet zone located at the toe of the downstream embankment slope should be periodically observed to determine if a seepage condition is developing. Little Youghiogheny Site No. 2 is classified as a 'small' size, 'high' hazard dam based on guideline criteria. Soil Conservation Service hydrological/hydraulic design computations indicate dam and spillway capacity is adequate to pass the PMF (100%) without overtopping the dam embankment. Therefore, spillway capacity is adequate and in accordance with recommended criteria.
