There will be a complete closure to both the large and small locks at the end of the month in order for divers to inspect and close a saltwater drain screen structure in preparation for the salmon migration.
The closure will be on Wednesday, May 29 from 8am to 4pm.
The screen structure is located just upstream of the locks, and prevents salmon from entering the lock’s saltwater return intake. Divers will close 10 different 10-foot by 6-foot doors and inspect the 30 by 60 curved, mesh screen.
The work is part of an annual process done prior to start of the mid-June salmon migration season. Crews will then perform monthly inspections until the doors re-open mid-September.
All except emergency vessels will be prohibited from passing through the locks during the closure.
