The examination of documents and visual inspection of the Watervliet Lower Dam and appurtenant structures did not reveal conditions which constitute a hazard to human life or property. The discharge capacity of the spillway is inadequate for all storms in excess of 77% of the PMF (Probable Maximum Flood). During the 1/2 PMF event, the maximum water surface will be 4.4 feet below the top of dam. However, the dam will be overtopped by 2.0 feet during the full PMF; therefore the spillway is assessed as 'Inadequate'. The following problems were observed which require remedial action within one year of notification to the owner: Clean the deteriorated concrete and repair those areas where significant concrete is needed and where reinforcing bars are exposed; Repair the construction joints and cracking of the spillway; Remove the debris and sediment from the vicinity of the intakes and the downstream channel; Consider removal of penstock; Remove the tree and brush growth from the abutments upstream area and downstream channel. Provide a program of periodic cutting at these locations; Provide a program of periodic inspection and maintenance of the dam and appurtenances including periodic removal of sediment and debris; Develop an emergency action plan for notification of downstream residents and the proper governmental authorities.
