According to the Lewiston Tribune, the dams will be taken offline to undergo maintenance and repairs that have been years in the planning. The dams will be shut down Monday, Dec. 12 and remain closed until Monday, March 20.
The maintenance, conducted by the U.S. Army Corps of Engineers, will be costly. Replacement at a gate and lock controls at The Dalles alone will cost upwards of $10.5 million.
The Tribune reports grain barges from the Lower Snake and Columbia river system have already been floated to a location below the dams, where they'll stay throughout the winter. That means the wheat shipped before the shutdown will have to represent a large share of what will be available to overseas customers during the outage, according to the Idaho Wheat Commission.
At the same time, the federal government is taking public comment on the future of the dams on the Columbia and Snake rivers, including the possibility of removal. U.S. District Court Court Judge Michael Simon ordered the government in May to find alternative solutions to the dam system, which environmental advocates insist continually threatens salmon and steelhead trout.
