According to the Columbia River System Operations Environmental Impact Statement released in 2020, breaching the lower Snake River dams could:

  • Double the risk of region- wide blackouts
  • Add an additional 3 million metric tons of carbon to the atmosphere each year from fossil-fueled electricity
  • Increase the region’s electricity costs by $800 million a year and the Bonneville Power Administration’s power costs by 50%, which could increase energy costs at homes by up to 25% or more
  • Result in the loss of $540 million per year in regional economic productivity
  • Result in the loss of 4,900 jobs as a result of higher electricity costs
  • Reduce social welfare by $458 million annually from the loss of irrigated land and farm laborers
  • Add 79,000 more semi-trucks to the road each year

The Environment Impact Statement was supported by Biological Opinions from both NOAA Fisheries and the U.S. Department of Fish and Wildlife.

The future of the dams is in your hands!
