Large Ballard lock closed for annual maintenance, tours are sold out

Just like every year, the Army Corps of Engineers has closed and emptied the large lock at the Hiram M. Chittenden Locks for annual maintenance. Crews will scrape barnacles off the walls and check all the mechanical systems.

It’s always fascinating to see what lies 55-feet down — both in the lock and inside the chambers that feed it. However, the VIP tours, which begin today, have sold out. Back in 2009, we tagged along with the Army Corps and took some photos and videos.

The money raised from the tours goes toward the upcoming Fish Ladder Education Center project, which begins later this fall.

Crews will be working on the large lock through Nov. 22nd. Until then, all marine traffic is routed through the small lock.
