Highly endangered runs of wild salmon must pass through four lower Snake River dams during migration to and from the ocean. For over 20 years, controversy has surrounded debate over the possible breaching of these four lower Snake River dams. Environmentalists and regional native tribes have advocated for dam removal as the most effective way to address endangered salmon runs, while others warn that removing the dams will adversely affect electricity generation, irrigation, and barge transportation.
