National Dam Safety Program. Brocton Reservoir (Inventory Number NY 785), Lake Erie Basin, Chautauqua County, New York. Phase I Inspection Report
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. Examination of available documents and a visual inspection of the dam did not reveal conditions which constitute an immediate hazard to human life or property. However, the dam has some deficiencies which require further investigation and remedial action. Using the Corps of Engineers screening criteria for review of spillway adequacy, it has been determined that the dam would be overtopped for all storms exceeding approximately 52 percent of the PMF. The overtopping of the dam could cause the erosion of the west embankment-spillway contact and downstream face of the west embankment resulting in spillway failure, thus increasing the hazard to the loss of life downstream. The spillway is, therefore, considered to be 'inadequate'. Structural stability analysis based on available information and the visual inspection indicates that the stability of the spillway section against overturning is inadequate for the loading conditions of maximum ice load at normal pool as well as one half and full PMF. A wet area, detected during the visual inspection(s) along the toe of the east embankment could, depending on the source of the wet area, affect the stability of the east embankment.
