National Wetlands Inventory (Arcs)
- This polyline layer represents river and stream features as created by the National Wetlands Inventory (NWI) program, administered by the United States Fish and Wildlife Service. The NWI project was established to generate information about the characteristics, extent and status of the Nation's wetlands and deepwater habitats. This information is used by Federal, State, and local agencies, academic institutions, U.S. Congress, and the private sector. The Emergency Wetland Resources Act of 1986 directs the Service to map the wetlands of the United States. The Act also requires the Service to produce a digital wetlands database for the United States. The layer is named NWI_ARC. Also see the wetlands area layer NWI_POLY.
