Columbia Snake River System Extended Lock Closure

The federal government is making significant investments in the Columbia Snake River System (CSRS). Beginning December 2010, the U.S. Army Corps of Engineers is planning a 14-16 week extended lock outage on this system, to make necessary major maintenance repairs to The Dalles, John Day and Lower Monumental. Extended lock closures of this kind are very unusual, but are necessary to maintain the integrity of the transportation system. The infrastructure investments and maintenance repairs being made during this outage will have long term benefits for the entire Northwest, a region that is poised for tremendous growth.

PNWA is working closely with the Corps and navigation stakeholders to minimize impacts on river users this outage. PNWA continues to work to assure the reliability of navigation in the Northwest.
