The HydroID is a key attribute in the Arc Hydro geodatabase used for feature identification and establishment of relationship in the geodatabase. Every feature an Arc Hydro geodatabase is given a HydroID which becomes its unique identifier (HydroID differs from OBJECTID as HydroID is unique across all the classes in the geodatabase while OBJECTID uniquely identify features/rows in a single table/feature class)
