"Several tributaries to the upper Wenatchee River (Nason Creek, Little Wenatchee, White, and Chiwawa Rivers) are currently being considered for nutrient enhancement. At this time they are being studied to assess their nutrient status. My research is one component to this broader study. In the White River I am calculating benthic macroinvertebrate production in reaches above and below the spawning grounds of sockeye salmon (Oncorhynchus nerka). Comparisons between upper and lower reaches will allow me to assess the influence spawning salmon have on the composition of the macroinvertebrate community as well as their production. In the remaining tributaries I am conducting a bioassessment by applying metrics of the benthic macroinvertebrate community to established indices of stream health."
