Hydrologic Unit Code definition

Hydrologic Unit Code or "HUC" means a watershed unit established in the most recent version of Virginia's 6th Order National Watershed Boundary Dataset.
Hydrologic Unit Code or "HUC" means a watershed unit established in the most recent version of Virginia's 6th Order National Watershed Boundary Dataset unless specifically identified as another order.
Hydrologic Unit Code or "HUC" means a numeric United States Geological Survey code that corresponds to a watershed area. Each area also has a text description associated with the numeric code.

Eight-digit HUCs are used for large watersheds known as subbasins; 10-digit HUCs divide the large subbasins into watersheds; and 12-digit HUCs divide watersheds into subwatersheds that capture local tributary systems.
