Learn the Facts

Survival of juvenile salmon and other fish species passing through the Walla Walla District dams has continued to significantly improve since the initial installation of the dams due to research and the substantial investment in modification of structures and operations. Walla Walla District has one of the highest overall fish passage survival percentages in the world for dams of this size.

Quick Facts

  • Barging is the lowest cost, cleanest mode
    of transport available.
  • The Columbia Snake River System is the top
    wheat export gateway in the U.S. and the third
    largest grain export gateway in the world.
  • Power blackouts are predicted by 2026
    even with the dams intact. Without the dams
    the risk of blackouts will increase
    dramatically.
  • Breaching the 4 lower Snake River Dams will
    destroy 1,000s of jobs and millions of
    dollars in economic activity in the Pacific
    Northwest with no guarantee of fish returns.
  • Facts: Fish numbers fluctuate due to ocean
    conditions, commercial fishing, & predators.
  • Flushing water at high volumes poisons fish.
  • The 4 lower Snake River dams provide enough
    clean energy to power 1.87 million homes.
  • BPA reports the loss of power revenue from
    breaching the Snake River damsrangesfrom
    $264 to $350 Million each year.
  • A typical 4-barge tow on the river moves the
    same amount of cargo as 140 rail cars or 538
    trucks. The NW Power & Conservation
    Council estimates that CO2 emissions would
    increase by at least 3 million metric tons
    each year without the Lower Snake River
    Dams.
  • Hydropower makes up about 90% of the NW’s
    renewable energy.
