Five Week Lock Closure For The Dalles Dam Planned

Commerce moving up and down the Columbia River will be at a stand-still for up to five weeks beginning February 13.  The U.S. Army Corps of Engineers is extending its annual closure of navigation locks on the Columbia and Snake river dams annual basis for maintenance and repairs an extra three weeks, in part to repair the downstream miter gate at The Dalles Dam.  Technicians found damage at The Dalles navigation lock during last year’s planned closure, forcing an emergency extended outage.  Engineers will perform repairs during the five-week closure, which will end March 19.  Engineers will also perform annual maintenance on the navigation locks at Bonneville Dam and John Day Dam during the outage.
