Stream channels provide habitat for aquatic animals, such as fish and aquatic benthic invertebrates. Associated with the channel are near water habitats important to amphibians, reptiles, birds, and mammals. Water snakes and alligators are representative examples of near water reptiles; whooping cranes and lesser plovers typify water-oriented birds; and the muskrat, mink, and beaver are common mammals found in or near river channels. This paper first discusses the relationship between the stream channel and the habitat for fish, birds, and water snakes; and second, presents a situation where changes in flows cause the channel to change and consequently the relation between physical habitat and flow.
