Final authority to breach the four lower Snake River dams remains with the 535 members of Congress.

But agricultural stakeholders, tribes and environmental groups agree on one thing: The Columbia Basin Restoration Initiative recently signed by the Biden administration, four Northwest tribes and the states of Oregon and Washington is a pathway to breaching the dams.

The state and Bonneville Power Administration could compensate irrigators up to about $760 million during disruption caused by breaching all four lower Snake River dams and replacing their irrigation benefits, according to a new study from the Columbia-Snake River Irrigators Association.

U.S. District Court Judge Michael Simon has approved the memorandum of understanding between the Biden administration and plaintiffs in a lawsuit over Snake River dam operations, staying the lawsuit through December 2028, with the possibility of another five year extension.

The Ice Harbor Lock is 675 feet long and 86 feet wide, with a minimum depth of 16 feet. It can accommodate a tugboat pushing up to four barges. Proponents of the dams say the use of barges on the Snake and Columbia rivers is far more efficient than using trucks or railroad.
