Examples of HUC 6 in a sentence

  • The WRP uses the Hydrologic Unit Code (HUC) watersheds at two scales: HUC 4 and HUC 6, where HUC 4 watersheds are mostly larger than 500 square kilometers and HUC 6 watersheds are entirely nested within HUC 4 watersheds and mostly larger than 200 square kilometers.

  • The United States is divided and sub-divided into successively smaller hydrologic units which are classified into different levels: Regions (HUC 2), Subregions (HUC 4), Basins (HUC 6), Subbasins (HUC 8), Watersheds (HUC 10), and Subwatersheds (HUC 12).

  • The Network will address the atmospheric deposition by monitoring wet and dry atmospheric deposition near the mouths of coastal HUC 6 outflows.

  • A CWE analysis would be conducted at a smaller scale, HUC 7, to determine if any portion of the larger HUC 6 watershed is still over a threshold of concern (TOC).

  • However, Sites located near river confluences with differing adjacent HUC 6 watersheds but within the same EPA Level IV Ecoregion as the Site may be reviewed by USACE for GSA consideration.

  • Adjacent HUC 8 watersheds within the same EPA Level IV Ecoregion as the Site but within a different HUC 6 will not typically be included within a GSA boundary.

  • If no HUC 7 is over TOC, an additional 500 acres could be approved within the HUC 6 boundary.

  • Isolated wetlands require replacement in HUC-8 or county.53 IL: state- funded impacts almost always require higher credit ratio for banks outside of HUC-8 (2, 3, or 5.5 depending on severity of impact).54Memphis (AR, IL, KY, MO, MS, TN)HUC-8, HUC- 6, EDU, AR WPRAll service areas determined case-by-case.

  • This framework delineates 12 sixth-field Hydrologic Unit Code (or HUC 6 watersheds (Map 1, Appendix A.) These watershed boundaries are a significant departure from the fifty 6 HUC watersheds used in previous watershed assessments.

  • When a CWE analysis supports a watershed is below a TOC and will remain below a TOC, the cutting and removal of fire killed (or dying) trees may only occur on up to 1,000 acres spanning two HUC 6 watersheds, with a maximum of 500 acres per HUC 6 watersheds (Figure 2) where the need for temporary road access remains less than 500 feet.
