Prominent fishery biologist Peter Moyle replies that the San Joaquin will be an ideal place for salmon in the future. It will be a pipeline of chilly snowmelt from the high Sierra.
But for years, nobody has been able to settle that debate with science. Now, using a $1.5 million National Science Foundation grant, the University of California at Merced is working on at least part of the answer — a profile of the future San Joaquin River. Continue reading
A dozen experts in relevant fields are being paid to review the U.S. Environmental Protection Agency’s study of how a large mine would affect Bristol Bay’s prized salmon runs. Continue reading

After years of going begging, Northern California is awash in salmon. Charter boats are booked up to two weeks in advance, and anglers claim to be bagging their limits before noon.

Most of the salmon caught in California come from hatcheries in the Sacramento Valley, yet it turns out not much is known about these fish even though they are bred by hand. Continue reading
Minute amounts of copper from brake linings and mining operations can affect salmon to where they are easily eaten by predators, says a Washington State University researcher. Jenifer McIntyre found the metal affects salmon’s sense of smell so much that they won’t detect a compound that ordinarily alerts them to be still and wary. Continue reading

The timber industry is hoping that the U.S. Supreme Court will maintain business as usual on controlling muddy water running off logging roads into salmon streams. Continue reading
In the wilderness of Washington state’s Olympic National Park, hydraulic hammers chip away at the Glines Canyon Dam in the largest dam-removal project in U.S. history. Continue reading
A federal judge who spent a decade presiding over one of the most contentious environmental court fights in the Northwest — the fate of endangered salmon in the Columbia River Basin and four hydroelectric dams that interrupt their migration — has said in a recorded interview that the dams should be removed to help the fish.
