Abstract		The United States was divided and sub-divided into successively smaller hydrologic units. Each hydrologic unit is identified by a unique hydrologic unit code (HUC) consisting of six or more digits. This layer contains a composite of the 6, 8, 10 and 12 digit HUCs for the state of Arizona. Use the TYPE field to seperate HUCs by HUC class: HUC06, HUC08, HUC10, and HUC12.
Known errors/qualifications		This layer has overlaping data and should not be used as a coverage.
