Water: Rivers & Streams

Rivers & Streams

There are over 3.5 million miles of rivers and streams in the U.S., covering an enormous and diverse landscape. Not surprisingly, the condition of the nation’s streams and rivers varies widely. Cities and town, farmlands, mines, factories, sewage treatment facilities, dams, and many human activities on the land have significant impacts on the quality of our flowing waters. Understanding the condition of rivers and streams is critical if we are to develop effective plans to maintain, manage, and restore them.
