A selective merging of the 6th level units was done in 1996 to produce a 5th level hydrologic unit system, also referred to as the 11-digit hydrologic unit system. While both the 5th and 6th level systems were developed using established hydrologic unit standards, only the 5th level set was completed in all the states surrounding Virginia.

After you learn what a watershed is, It is important that you understand how to determine watershed boundaries and become familar with our state's topographic maps. West Virginia has 32 watersheds divided according to hydrologic unit codes (HUC) that contribute to the Chesapeake Bay and the Gulf of Mexico. For example, Hydrologic Unit number 02080206 is named the Lower James, for the downstream part of the James River watershed in Virginia. The first 2-digits of the code indicate that the Hydrologic Unit is part of the Mid Atlantic Region, as shown on the map below. Six Easy Steps to Finding Your 12‐digit Hydrologic Unit Code (HUC) I.

Hydrologic Unit Maps The U.S. is sub-divided into successively smaller hydrologic units which are classified into four levels: regions, sub-regions, accounting units, and cataloging units. Each unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on its classification.
