Description: This is the 4 digit Hydrologic Unit Code Map. The United States is divided and sub-divided into successively smaller hydrologic units which are classified into four levels: regions, sub-regions, accounting units, and cataloging units. The hydrologic units are arranged within each other, from the smallest (cataloging units) to the largest (regions). Each hydrologic unit is identified by a unique hydrologic unit code (HUC) consisting of two to twelve digits based on the four levels of classification in the hydrologic unit system. This layer has 4 Digit HUC Codes.
