Willamette Basin is Seriously Degraded


No surprise here, the Willamette River and many of its tributaries are seriously degraded. Oregon's Department of Environmental Quality recently released a report on the level of degradation in the system and found that up to 70% of the stream areas in the system had summer temperatures which were inhospitable to salmon. Furthermore, urbanization and agriculture have left almost half of the stream miles in the system without adequate stream side vegetation and have seriously compromised the biological health 80% of the streams flowing through urban and agricultural areas. The one bright side is that some of the habitats which are not urban or agricultural are actually in pretty good shape. See the full article in the oregonian.
