Macroinvertebrate communities, physical habitat, and water chemistry were sampled from 63 stream reaches in the Tualatin River basin in fall 2001 to assess the condition of macroinvertebrate communities in relation to land use patterns and instream physicochemical conditions. Thirty seven low-gradient and 26 high-gradient reaches were sampled.
