National Dam Safety Program. Greenhaven Correction Facility Dam (Inventory Number N.Y. 11700), Lower Hudson River Basin, Duchess County, New York. Phase I Inspection Report,
Abstract
This report provides information and analysis on the physical condition of the dam as the report date. Information and analysis are based on visual inspection of the dam by the performing organization. Examination of the available documents and visual inspection of the Greenhaven Correction Facility Dam did not reveal conditions which constitute a hazard to human life or property. Using the Corps of Engineers screening criteria for review of spillway adequacy, it has been determined that the concrete gravity dam would be overtopped for all storms exceeding approximately 38.8 percent of the Probable Maximum Flood (PMF). Although the spillway capacity is inadequate from a hydraulic and hydrologic point of view, the hydraulic inadequacy will not affect the stability of the concrete dam section during overtopping nor the safety of the dam since it is supported on sound rock and overtopping will cause neither significant erosion at the toe or abutment nor undermine the foundation. In addition the dam stability is considered to be adequate against overturning and sliding. (Author)
