The Dalles Navigation Lock To Close For Three Days
6 a.m. Dec. 5 to 6 p.m. Dec. 7.
The Dalles navigation lock will be closed for the better part of three days next week for repairs to its downstream gate. It will be closed from 6 a.m. Wednesday, December 5 until 6 p.m. on Friday, December 7. Navigation locks at Bonneville and John Day dams will remain open for normal operations. The Army Corps of Engineers will replace a bushing on the south downstream miter gate gudgeon arm pin. The bushing attaches the top of the gate to the lock wall and allows the gate to move during operations. The Corps expects the repairs to allow the lock to operate until the annual Columbia-Snake rivers two week lock closure in March, when workers will replace the remaining bushings on the both the north and south gates.
