Great news for this fishery, and sustainability.
"...Biologists credit habitat improvements in the Okanagan Basin of northern Washington and Canada, improved dam operations, and favorable ocean conditions for the numbers....
Ritchie Graves, a NOAA Fisheries Service biologist who makes sure federally owned dams are living up to their Endangered Species Act obligations not to kill too many salmon, said the survival rate for young salmon swimming downstream to the ocean has been higher than ever the past three years, hitting about 50 percent for sockeye.
Those improved dam operations have also benefited chinook, coho, chums, pinks and steelhead, said Graves. The six species combined accounted for 1.8 million salmon over Bonneville in 2010, compared to 471,144 in 1938."
