“Fish communities in Fanno Creek tend to have few species and low abundance due to culverts and urbanization. The native reticulate sculpin is by far the most common species, and cutthroat trout are found in some tributaries. Although Fanno has low numbers of fish, over 99 percent of the captured fish are native.”
