Acoustic tags and numerical river models are two technologies developed by researchers at the Department of Energy's Pacific Northwest National Laboratory that are helping improve salmon passage at the Columbia Basin's hydroelectric dams. An average of 76 percent of juvenile Chinook salmon that pass through the lower 100 miles of the Snake River and its three hydroelectric dams survived the trek in the spring of 2008, according to a joint study.
