Abstract:

This report provides information and analysis on the physical condition of the dam as of the report date. Information and analysis are based on visual inspection of the dam by the performing organization. The examination of documents and the visual inspection of the Port Jervis Reservoir No. 3 did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some problem areas which require additional studies to evaluate conditions affecting the dam. Using the Corps of Engineers screening criteria for the initial review of spillway adequacy, it has been determined that the embankment would be overtopped for all storms in excess of 54 of the Probable Maximum Flood PMF. Therefore, the spillway is adjudged as inadequate. There are several areas where seepage was found. Some point seepage along the toe of the embankment and in the spillway are the major concerns. It is recommended that within three months of the date of the notification of the owner, additional engineering investigations of the seepage at the toe of the dam and the spillway should be commenced. Remedial actions deemed necessary based on the results of these investigations should be completed within eighteen months of the notification. Author
