National Dam Safety Program. Goshen Reservoir Number 1 Dam (Inventory Number N.Y. 488), Lower Hudson River Basin, Orange County, New York. Phase I Inspection Report,
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 Goshen Reservoir 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 and remedial work. The most serious of these deficiencies are the two areas of seepage on the downstream slope of the dam. First is at the end of a grouted stone spillway channel and the second is at the toe in the center of the dam. It is recommended that within six months from notification, an engineering investigation is initiated to determine the sources of the seepage found. Using the Corps of Engineers' screening criteria for the initial review of spillway adequacy, it has been determined that the embankment would be overtopped by all storms in excess of 51% of the Probable Maximum Flood (PMF). Therefore, the spillway is adjudged as 'inadequate.' (Author)
