National Dam Safety Program. Watervliet Upper Dam (Inventory Number NY 1356), Lower Hudson River Basin, Albany County, New York. Phase I Inspection Report

摘要

Examination of documents and visual inspection of the Watervliet Upper Dam and appurtenant structures did not reveal conditions which constitute a hazard to human life or property. The discharge capacity of the spillway is inadequate for all storms in excess of 55% of the PMF (Probable Maximum Flood). During the 1/2 PMF event, the maximum water surface will be 1.2 feet below top of dam. However, the dam will be overtopped by 2.3 feet during the full PMF; therefore, the spillway is assessed as Inadequate.
