An extended closure of the Columbia Snake River System (CSRS) is scheduled from January 14 to March 29, 2024, to replace major components at the John Day and McNary dams on the Columbia River and at the Lower Monumental, Little Goose, and Lower Granite dams on the Snake River.
Similar extended closures occurred in 2010 and 2016. This maintenance represents a forward-thinking investment by the U.S. Army Corps of Engineers to ensure this critical waterway remains operational for decades to come.
The additional improvements will help the U.S. wheat export supply system remain the most reliable in the world.
