During operational commissioning/testing on March 15, 2017, Corps and Contractor personnel discovered loud, unusual noises associated with the gate lifting mechanisms in both towers that could negatively impact safe navigation lock operations. Staff continues to assess the cause of these noises and determine potential fixes. The targeted return to service date at the Ice Harbor lock is now March 23, 2017 at 2359 (11:59 PM) PST. Updates will be provided as more information becomes available.

The most recent schedule assessment for Little Goose indicates an anticipated completion of the gate repairs no later than March 31, 2017. The government will require two days following that to water up and test the lock. The targeted return to service date at Little Goose’s lock is now April 2 at 2359 (11:59 PM) PST, barring any further complications with the work. Updates will be provided as more information becomes available.
