DELAY IN RETURN TO SERVICE LITTLE GOOSE NAVIGATION LOCK

Little Goose Lock and Dam – Snake River Mile 70.3; Chief Operator on Duty: 509-399-2233 x231

The Corps will require an additional nine calendar days at Little Goose Lock and Dam to complete repairs on the downstream navigation lock gate, delaying return to service of the lock until 11:59 p.m. on April 11, 2017.

Operational testing of the north gate revealed that the new pintle heel was not replaced in the correct position under the previous contract. The north gate will require machining of the gate quoin blocks to correct the deficiency and return the gate to service.

Surveying was performed on the South gate, confirming the south pintle heel was also installed out of position under the previous contract. Corrections have been made, and the gate is being moved into place to verify the alignment.

The Corps will continue to keep navigation stakeholders informed of any changes in Little Goose’s lock status as soon as information can be confirmed.
