Wetlands and Watersheds
The 19th-century explorer and geographer John Wesley Powell defined a watershed as "a bounded hydrologic system, within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community." Powell wisely recognized that all living things in a watershed, including waterfowl and people, are united by and dependent on its central element—water.
