Abstract:

Based on the criteria established for these studies, Whitney Lake Dam is judged to be in fair condition. The recommended Spillway Design Flood SDF for the size and hazard classification of the dam varies between the 100-year flood and 12 of the Probable Maximum Flood PMF. The 12 PMF was selected as the SDF. The existing spillway will not pass the 100-year peak flood inflow. If the stoplogs on the spillway crest were removed, the spillway capacity would increase significantly, but it would still be insufficient to pass the 100-year peak flood inflow. The spillway capacity is rated as inadequate. Several deficiencies were observed at the dam. The most serious are at the spillway, which is structurally deteriorated. Although some maintenance has been performed, the existing maintenance program could be upgraded.
