The theory that suggest “the more the better” typically holds true when evaluating streams and watersheds. The more different kinds of fish present, usually, the better the water quality in the contributing watershed. In some regions of the Tennessee Valley, a relatively undisturbed small stream (e.g., 50-60 square miles) can support between 30 and 40 species of fish, which offers just a subsample of the nearly 240 species that occur throughout the Tennessee Valley.
