"The removal plan has the backing of several Native American tribes on the Klamath who rely on the river for salmon fishing, as well as farmers who depend on its water for irrigation. The plan also has the support of PacifiCorp, Warren Buffett's power company, which owns the dams.
Buffett's company could benefit from dam removal because it might cost more to install the required modifications for fish passage if the dams remain. But if dams come down, salmon would be the biggest winners."
But others argue that, in addition to the dam removal, water quality issues would also play a crucial role in helping the salmon recover.
