Abstract
Area features such as Lakes, Reservoirs, Wide Streams and Rivers, and Unspecified Open Water features.

Purpose
HydroWaterBody is derived from the REGION.SHAID feature class of Release coverage 6.  Subtypes were used to differentiate between WaterArea and WaterBody features.  Many of the main attributes with WaterArea features are stored on the FlowLine that flow through them.  WaterBody subtype was created to mimic the structure of both the ArcHydro and NHD data models.  These data models separate flow features and area features such as lakes and reservoirs from streams and ditches.  The separation of subtypes for WaterArea and WaterBody occurred to create relationships between theses features in Topology and Relationship class validation.
