When salmon swim through dam turbines, the changes in pressure can be catastrophic to their bodies. Researchers are trying to figure out how improve fish survival rates. And the U.S. Army Corps of Engineers is paying attention. Reporting for EarthFix, Courtney Flatt has more.

Environmentalists, farmers and irrigators could play a bigger role in creating long term management policies for Columbia Basin salmon and steelhead. The government has asked two university programs in Oregon and Washington to act as mediators over the next six months, talking with more than 200 organizations, states and tribes in order to find a better way of managing fish.

Working for Idaho's Extinct Coho Salmon

The Northwest’s declining salmon runs have spurred marathon legal battles and inspired billions in spending to save the iconic species.

But Idaho’s coho salmon were never listed as endangered before they went extinct in 1987. Very few people noticed when the fish were gone. But the Nez Perce Indian tribe noticed. And thanks to its extraordinary efforts, coho are once again returning by the thousands to Idaho waters.

Earthfix reporter Aaron Kunz explains.

In Northwest streams, high temperatures and low flow levels are creating harsh conditions for fish. That’s the finding of a new study.

Salmon the Focus of Northwest Rivers Initiative

Dams, agriculture, urban development -- they’ve all contributed to the loss of quality habitat for Northwest salmon. EarthFix reporter Aaron Kunz recently visited an Idaho river where a historic gold mine has left problems behind for salmon and steelhead. Here’s his report on what’s being done to clean things up.

The Salmon River is one of the longest free-flowing rivers in the Pacific Northwest. The mountains, clean water and abundant fish and wildlife have attracted hundreds of people like Jerry Meyers, who calls this place home.

Supporters of an effort to stop the government from killing sea lions at Bonneville Dam made their case to a federal judge in Portland Friday. The animals are targeted because they feed on endangered salmon.

Biologists say the sea lions that scoop up fish at the foot of Bonneville dam on the Columbia river have killed more sturgeon this year than salmon. Amelia Templeton reports.

A fire that burned roughly 250 acres in Mason County two weeks ago has been put out. Now biologists are concerned about the potential impacts on local salmon runs.
