Where Rivers Are Born: The Scientific Imperative for Defending Small Streams and Wetlands

Our nation’s network of rivers, lakes, and streams originates from a myriad of small
streams and wetlands, many so small they do not appear on any map. Yet these headwater streams and wetlands exert critical influences on the character and quality of downstream waters. The natural processes that occur in such headwater systems benefit humans by mitigating flooding, maintaining water quality and quantity, recycling nutrients, and providing habitat for plants and animals. This American Rivers paper summarizes the scientific basis for understanding that the health and productivity of rivers and lakes depends upon intact small streams and wetlands.
