Inland Columbia Snake River System Operations & Maintenance

 

PNWA is pleased to report that the federal government continues to plan and invest in the future of the Columbia Snake River System (CSRS).  Building upon past successes, the U.S. Army Corps of Engineers’ Portland and Walla Walla Districts continue to systematically evaluate our inland infrastructure, and target the highest priority repairs. Each March, both districts coordinate a two to three week routine maintenance closure of the eight navigation locks on the inland system. The brief closures allow for targeted inspection and repairs to ensure limited interruptions in service for the remainder of the year.  The next March maintenance outage will last two to three weeks depending on the project, and will begin on March 3, 2018.

In addition to these March closures, the Corps has also executed two extended lock closures.  These have varied in length from 14-15 weeks, and are necessary to repair and/or replace large components like new lock gates and operating machinery.  These closures are planned in close coordination with shippers, growers, ports, towboat companies, and many others.  While infrequent, closures of this duration are sometimes necessary to maintain the integrity of the entire transportation system.

PNWA supports the operations and maintenance of our inland Columbia Snake River System, so that it many continue providing a safe, efficient route for cargo for the entire Northwest and the nation.
