Hydrologic Unit Code (HUC) 1
Hydrologic Unit Code (HUC) 1 : A hierarchical, numeric code that uniquely identifies hydrologic units. The first two digits identify the region, the first four digits identify subregions, the first six digits identify accounting units, and the full eight digits identify subbasins. From the above example, (definition of hydrologic unit), the hydrologic unit codes are: 02 - the region (Mid-Atlantic), 0206 - the subregion (Upper Chesapeake), 020600 - the accounting unit (Upper Chesapeake. Delaware, Maryland, Virginia, and Pennsylvania), 02060002 - Zeroes in the two-digit accounting unit field indicate that the accounting unit and the subregion are the same. Zeroes in the two-digit subbasin field indicate that the subbasin and the accounting unit are the same
