Abstract:

Based on criteria established by the Department of the Army, Office of the Chief of Engineers OCE, the appropriate Spillway Design Flood SDF is the 12 PMF. The spillway will pass 15 percent of the Probable Maximum Flood PMF or 30 percent of the SDF without overtopping the dam. During the SDF, the dam will be overtopped by a maximum of .4 ft for a period of 4 hours at a maximum velocity of 2.7 fps. Flows overtopping the dam during the SDF are not considered detrimental to the embankment with respect to erosion. The spillway is judged inadequate, but not seriously inadequate. The visual inspection revealed no apparent problems, however, two saturated areas encountered on the downstream embankment slope above the toe are concern. An evaluation of the stability condition could not be made since there is insufficient design and construction data for this structure.
