Increased Lockage Time and McNary’s Navigation Lock

Navigation Notice: 205420/24-01
Date: 11/18/2023 01:10 thru UNTIL FURTHER NOTICE

Due to mechanical issues with one of the navigation lock drain valves, the valve is removed from service while maintenance crews are performing repairs to the mechanical system. There is currently no firm estimate for when the lock will return to full service. Until further notice, lockages are predicted to require an additional 15-20 minutes to complete.

Once repairs are completed, an amendment to this notice will be issued.

Project affected: McNary Lock and Dam, located at Columbia River Mile 292.
