NEW YORK STATE DEPT OF ENVIRONMENTAL CONSERVATION ALBANY
Pagination or Media Count:
The Ischua Creek Watershed Project Site 4 consists of an earth dam with a principal spillway outlet pipe passing from a reinforced concrete riser structure through the embankment and two grass lined earth auxiliary spillways passing around the north and south ends of the embankment. The examination of available engineering documents and visual inspection of the Ischua Creek Site 4 Dam did not reveal conditions which constitute a hazard to human life and property. The total discharge capacity of the combined principal and auxiliary spillways is adequate to impound and safely discharge the floodwater resulting from the Probable Maximum Flood, therefore, the spillway is deemed to be adequate.
