The Ice Harbor navigation lock will remove one fill valve at a time from service starting 0700 on 6 February 2026 and continuing to the start of the District navigation lock maintenance outage on 21 February 2026. This work will facilitate a metrology survey of the fill tainter valve shafts for future replacement of the tainter valves. Upstream lockages will require an additional 15 minutes to complete with the lock operating on one fill valve.
