Following an emergency outage in 2014 to repair a failing gudgeon arm, additional work was required during the FY17 outage to complete replacement of the aging components of the gate. This project involved replacement of the remaining original gudgeon arm and linkage, replacement of the pintle assembly for both gate leafs. Structural repairs included resurfacing the quoin and miter, and crack repairs to structural members. Repairs are critical to ensure reliable gate operation.
