PORTLAND -- Repairs to the upstream navigation lock gate at Bonneville Dam are taking longer than planned.
Scott Clemans, spokesman for the U.S. Army Corps of Engineers' Portland District, said the work has been more difficult than expected.
The lock at Bonneville Dam closed for upstream gate repairs Sunday at 7 a.m. The gate was damaged Thursday during a routine operation to flush debris out of the upstream channel and through the lock.
The top of the gate was exposed to high water pressure and buckled when drain valves pulling water into the lock failed to close.
Clemans said the Corps expects a delay of no more than 24 hours, and should have a firm understanding Wednesday morning of how long the lock will be closed.
