The purpose of this manual is to provide users with mandatory technical criteria, field indicators and other sources of information, and recommended methods to determine whether an area is urisdictional wetland or not, and to delineate the upper boundary of these wetlands. The document can be used to identify jurisdictional wetlands subject to Section 404 of the Clean Water Act and to the 'Swampbuster'provsion of the Food Security Act, or to identify vegetated wetlands in general for the National Wetlands Inventory and other purposes. The term 'wetland' as used through this manual refers to juridictional wetlands for use by Federal agencies. This manual, therefore, provides a single, consistent approach for identifying and delineating wetlands from a multi-agency Federal perspective.
