The federal agencies responsible for restoring depleted species of fish in the Northwest are reporting success in improving the habitat of endangered salmon and steelhead.
A variety of fixes, such as eliminating culverts and barriers to aid fish passage, helped more than 1 million Chinook salmon return to Bonneville Dam in 2013. That’s a record, the agencies said in a report issued this month.
They credited habitat improvements with increasing the survival rate for key salmon and steelhead populations by 20 percent to 50 percent, depending on the intensity of the efforts.
“Well-designed habitat improvement projects that address limiting factors promote significant increases in fish survival and abundance,” according to the update on actions taken in the Columbia River Basin.
