    Hydrologic Unit Codes:
    "The United States is divided and sub-divided into successively smaller hydrologic units... Each hydrologic unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on the four levels of classification in the hydrologic unit system."

    Army Corps of Engineers Districts:
    "The US Army Corps of Engineers (USACE) has 8 divisions (also called Regional Business Centers) throughout the US with 41 district offices in the US, Asia and Europe, and field offices throughout the world. The USACE divisions and districts follow watershed boundaries, not state boundaries, so a state could be divided into several divisions/districts."
