The large lock at the Ballard Locks is closed to vessel traffic due to an electrical outage from a lightning strike Oct. 11, according to the U.S. Army Corps of Engineers, which operates the locks.

The maintenance crew is working to restore service, but the large lock is not expected to return to service until the end of the week at the earliest, according to a Army Corps of Engineers press release.

As more information on the large lock status becomes available, updates will be posted on the Corps of Engineers information line at 1.866.596.2635 and the Locks’ website.
