Abstract:

Wye Mills Dam consists of an earth fill embankment with a timber sheet core approximately 26 feet high and 832 feet long. Twin concrete box culverts 12 feet by 13 feet connect to a U-shaped concrete ogee spillway 107 feet long near the right abutment of the dam. Downstream the twin box culverts discharge to a 197 foot long channel 14 feet wide which carries flow under MD Route 404. The upstream and downstream dam embankment slopes rise at a rate of 3HIV with a top width of 10 feet. Based on the evaluation of the conditions as they existed on the date of the inspection and as revealed by visual observations, the condition of Wye Mills Dam is assessed to be good. The spillway capacity 95 per cent PMF is classified as inadequate because it will not pass the recommended spillway design flood of full Probable Maximum Flood PMF according to the recommended criteria. However, it is believed that the dam will safely pass PMF without endangering life and property and, therefore, additional detailed hydrologic studies are not warranted.
