National Dam Safety Program. Byram Lake Reservoir Dam (Inventory Number N.Y. 1175), Long Island Basin, Westchester 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 findings of Byram Lake Dam did not reveal conditions which constitute an immediate hazard to life and property. However, the dam has some deficiencies which require further investigation and remedial action. Using the Corps of Engineers screening criteria for initial review of the spillway adequacy, it has been determined that the dam would be overtopped by all floods exceeding 61 percent of the PMF. The maximum spillway discharge capacity is 18.4 percent of the peak PMF outflow. The spillway is therefore judged to be inadequate. The structural stability analysis based on available information, assumed strength parameters and material properties and visual inspection indicates that the dam is inadequate in overturning and sliding for all loading conditions except for the normal loading.
