Rivers are home to over 300 species of freshwater fishes and over 120 species of freshwater mussels, as well as countless small creatures that live on our river bottoms. Some animals, sensitive to environmental and chemical changes, are good indicators of the quality of water in our rivers. When water quality declines, some of these animals disappear, indicating that something is wrong. Rivers are important in defining the landscape and in creating a habitat for many of Tennessee's plants and animals. Some river systems even support unusual or rare animals and plants.
Rivers also have significant economic values that are of great importance, but are often overlooked.
Other river activities, such as boating and rafting, generate jobs, economic benefits and tax revenue to the state. Wetlands, aquatic wildlife and urban waterfronts are valuable, as well as the roles of rivers in flood protection and industrial support. Send comments to Department of Environment and Conservation.
