Both the large and small locks will be closed this Thursday from 8 a.m. to 1 p.m.
The closure will allow dive teams to inspect an “Adult Salmon Exclusion Structure” immediately upstream of the locks. The system was installed last year to keep the salmon from being trapped in the return system. The doors of the system were closed on June 1 to prepare for this year’s salmon run. Dive teams want to inspect it to make sure it is working properly.
Locks to close on Thursday
