Abstract:

The visual inspection and review of available data indicate that Duck Pond Dam is in fair condition. The lack of embankment protection from spillway flows and the inadequate spillway capacity are the primary deficiencies which cause concern for the safety of this dam. In accordance with the recommended guidelines, the Spillway Design Flood SDF for this facility is in the range of the 100 year flood to 12 the Probable Maximum Flood PMF. Based on the size of the dam and degree of downstream hazard, the selected SDF is the 100 year flood. The hydrologic and hydraulic computations indicate that the combination of reservoir storage and outlet works discharge capacity will not pass the SDF 100 year flood prior to overtopping the embankment. In accordance with the criteria outlined and evaluated in Section 5.5 of this report, the discharge capacity for Duck Pond Dam is considered to be inadequate.
