The hydrologic unit hierarchy is indicated by the number of digits in groups of two (such as HUC 2, HUC 4, and HUC 6) within the HUC code. In EnviroAtlas, HUC 4 represents the subregion level, delineating large river basins (shown in yellow in the image). HUC 8 maps the subbasin level, analogous to medium-sized river basins (about 2200

Hydrologic Unit Codes (HUCs) Explained. Watersheds are delineated by USGS using a nationwide system based on surface hydrologic features. This system divides the country into 21 regions (2-digit), 222 subregions (4-digit), 370 basins (6-digit), 2,270 subbasins (8-digit), ~20,000 watersheds (10-digit), and ~100,000 subwatersheds (12-digit).
