From U.S. Army Corps of Engineers

The Hiram M. Chittenden Locks in Ballard will close to all marine traffic 8 a.m. to 1 p.m., July 25 to complete last week’s monthly saltwater drain screen structure inspection.

U.S. Navy divers from Naval Base Kitsap will finish inspecting welds and pressure washing the screen, items they didn’t have time to complete during the July 17, 5-hour closure. The structure, immediately upstream of the locks, prevents salmon from entering the locks’ saltwater return intake. The divers, closed 10, 10-foot-by-6-foot doors and inspected the 30-by-60 foot curved-front, mesh screen structure June 6. Monthly inspections are required until the doors are opened mid-September.

The operation requires the Locks be closed to all but emergency vessels on emergency calls. The staff will make maximum efforts to complete the work as soon and as safely as possible. Boaters may call the lockmaster on duty at 206-783-7000 to verify the locks are open.
