Science Cafe - Elwha River Dam Removal

We've heard a lot about potential impacts of the dam removal on the Olympic Peninsula's Elwha River since it began in September 2011. How will salmon populations respond to the destruction of the two dams? In this Science Café, George Pess of NOAA's Northwest Fisheries Science Center explores how scientists track the dam's effects on salmon and what results they've discovered so far.
