The destruction of four dams on the lower Klamath river will open up hundreds of miles of salmon habitat. U.S. regulators approved the plan Thursday in a unanimous vote.
With Pacific Northwest salmon and steelhead on the brink of extinction, there are new efforts being brokered to save the famed fish.
Washington's orcas are hungry, because there aren't enough salmon for them to eat. State officials want to take out some dams to help them, but that would hurt Washington's wheat farmers.
Biologists think gulls are eating more juvenile salmon than they thought, and fish advocates are proposing to kill problem gulls. But opponents say dam modification is what's needed to protect salmon.
The growth of the country's farmed salmon sector has reached such a critical point that, if not addressed, may cause "irrecoverable damage to the environment," a government report says.
Warming oceans and development threaten the West Coast's wild salmon. So activists started a traveling celebration to draw attention to the plight of the sockeye in Canada's Fraser River.
Many consumers don't yet understand the label, but grocery stores are now buying from "salmon-safe" farms, which help protect fish by banning pesticides and keeping manure out of the land's waterways.
Historical photos show fishermen with chinooks almost as tall as they are. A century's worth of dam-building, overfishing, habitat loss and hatcheries has cut the size of the average fish in half.
Insect-rich floodplain water once supported the threatened fish, but it has been diverted. The project's end goal is to improve the likelihood that Chinook survive the trek to the ocean and back.
The tribe has fished in the Pacific Northwest's Klamath River for centuries, but the Chinook have been devastated by drought, disease, dams, and a long history of habitat destruction.
