| Short Description |
Stream macroinvertebrates were surveyed at several reaches in the Quilceda/Allen drainage to establish their value as an indicator of stream quality for salmon use. Four benthic samples were collected each from riffle and pool habitat. Quantitative physical measurements, along with water quality measurements, were made of the stream channels.

| Abstract | Long Description |
Stream macroinvertebrates were surveyed at several reaches in the Quilceda/Allen drainage to establish their value as an indicator of stream quality for salmon use. Four benthic samples were collected each from riffle and pool habitat. Quantitative physical measurements, along with water quality measurements, were made of the stream channels. High quality biological conditions were found at sites where the riparian corridor was visually intact. These sites had a high percentage of coarse gravel and cobble-sized stream bottom substrate. Additionally, canopy shading was related to biological condition of stream macroinvertebrate communities. Coho salmon (Oncorhynchus kisutch) use is not reported to occur in stream reaches that were severely degraded, physically and chemically. The response by the macroinvertebrate community to channel degradation was coincident with changes in reported salmon use. |
