A cruise ship travelling upstream on the Columbia River waits at Rufus Landing, just downstream of John Day Dam, July 26 during a temporary closure of the dam’s navigation lock due to a broken guide wheel on the lock’s upstream side gate. The Corps resumed vessel lockages the same evening using a floating bulkhead—a wall that can be moved in and out of place with a tugboat and essentially used as a temporary gate. Currently, vessel lockages, which typically take about 45 minutes, are taking twice as long. The guide wheels, two of which are attached to each side of the gate, act as rollers that keep the gate aligned as it moves up and down through its normal range of motion during lockages.
