Willamette River Superfund Site

April 4, 2012 4:06 p.m.

The Willamette River's Superfund site has had a long and contentious history ever since it was designated as a federally-mandated clean-up site back in 2000. Now the Lower Willamette Group has released a feasibility study, which it says has taken many years and $96 million to conduct. The Environmental Protection Agency will look at the various options and recommend a plan over the coming years. The costliest and longest option would be $1.7 billion and take 28 years to complete. We'll find out what happens next, and who decides.

Retangling the Willamette River

July 27, 2011 4:15 p.m.

The Willamette River looked much different 160 years ago. According to historical mapping (pdf) conducted by Stan Gregory, a researcher at Oregon State, and others, there used to be more islands, more side channels and a more consistent connection between the river and its floodplain. But that "wildness" was largely contained to allow farmers to grow crops closer to the river without fear of flooding. River traffic benefited, too. Travis Williams, the executive director of Willamette Riverkeeper, thinks the Willamette River has become too straight and too simple. He says that it's time to reconnect the Willamette River with its traditional floodplain. According to Williams, changes would benefit sensitive species by increasing habitat. He says that people can benefit from the changes, too. That's because increasing the ground area available to a river can mitigate the effects of extreme flooding. But some farmers with frontage on the Willamette don't like the idea of retangling the river. Randy Henderson, the owner of Thistledown Farm, says that this will result in lost farmland. And with increasing pressure on farms to give way to development, it's a sensitive subject.
