This data set consists of geo-referenced digital data and associated attributes created in accordance with the "FGDC Proposal, Version 1.0 - Federal Standards For Delineation of Hydrologic Unit Boundaries 3/01/02"(http://www.ftw.nrcs.usda.gov/huc_data.html). Polygons are attributed with hydrologic unit codes for 4th level sub-basins, 5th level watersheds, 6th level subwatersheds, name, size, downstream hydrologic unit, type of watershed, non-contributing areas and flow modification. Arcs are attributed with the highest hydrologic unit code for each watershed, linesource and a metadata reference file. The Watershed and Subwatershed hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. The smaller sized 6th level sub-watersheds (up to 250,000 acres) are useful for numerous application programs supported by a variety of local, State, and Federal Agencies. This data set is intended to be used as a tool for water-resource management and planning activities, particularly for site-specific and localized studies requiring a level of detail provided by large-scale map information. The dataset will be appended to a larger seamless nationally consistent geospatial database as other states complete their portion of the watershed boundary dataset. The dataset was created by the U.S. Geological Survey (USGS) in Utah, along with the U.S. Geological Survey in New Mexico, with full funding, cooperation, and oversight provided by the Natural Resources Conservation Service (NRCS) in New Mexico. All generated linework and attribution was reviewed and approved by NRCS in New Mexico along with other in state interagency partners.

This same number was used in every record that pertains to a subwatershed that resides within the same 10-digit watershed. Numbers were assigned in an upstream to downstream fashion.

Huc_12: Twelve Digit Hydrologic Unit Code - (REQUIRED) This field provides a unique 12-digit code for each subwatershed. Numbers were assigned in an upstream to downstream fashion. Where no downstream/upstream relationship could be determined numbers were assigned in a clockwise fashion.

States: States - (REQUIRED) The "States" field includes the names of all state(s) that the subwatershed falls within. The 2-digit postal abbreviation in upper case and in alphabetical order was used, separated with a comma. Ncontrb_a: Non-Contributing Area - (FIELD REQUIRED, ATTRIBUTES OPTIONAL) Drainage areas that do not flow toward the outlet of any hydrologic unit are considered non-contributing. If a non-contributing area is on the boundary between two or more hydrologic units, the non-contributing area is associated with the hydrologic unit adjacent to the low point on the boundary. This attribute should be the total of the non-contributing areas within a hydrologic unit calculated in acres.

Outlets created by ditching or other artificial drainage were not considered for this field. If an HU flows into an ocean or the Gulf of Mexico, this field was populated with "OCEAN" and if a HU flows into one of the Great Lakes the term "LAKE" was used. If a HU flows across international borders, "CANADA" or "MEXICO" was used depending on which country the HU drains into. If an HU is a closed basin, then the term "CLOSED BASIN"was used. Hu_10_name: Fifth Level Hydrologic Unit Name - (FIELD REQUIRED, ATTRIBUTES OPTIONAL) This field used officially recognized names only. This field was populated by following the directions in subsection 6.3 "Watershed and Subwatershed Naming Protocol". The name used to attribute the watershed was used only once within a 4th level unit.

Some examples include "true", "classic", "composite", and "remnant" hydrologic units. C - "Closed Basin" hydrologic unit - A drainage area that is 100% non-contributing. This means all surface flow is internal, no overland flow leaves the hydrologic unit through the outlet point.

These HU's are predominantly land with some water areas at or near the outlet(s).

Populate this field with the highest hydrologic unit level (smallest number) for the line (arc) represented by the record. Record the level using numbers 1 through 6 representing each level with 1 being the highest and 6 the lowest level. An example would be if a line represents a region, subregion, basin, subbasin, watershed, and subwatershed boundary, then this cell would be populated with a 1 (Region). Example two would be if a line is a subbasin, watershed, and subwatershed boundary, then the cell would get a 4 (Subbasin). Use one of the levels provided in the list below.

Arc/Info's topological checking program CLEAN was used to correct intersections without nodes, identify unclosed polygons and remove duplicate lines with the same beginning and ending nodes. All sliver polygons were removed either using eliminate, merge or manually in ArcEdit. General subwatershed boundaries were created using EDNA30. These general raster lines were used as reference lines for on-screen digitizing 2005-01-01T00:00:00 Linework was digitized to 24k map accuracy standards using the DRG's as the official base map as outlined in the standard. DOQQs were used as a reference in extreme manmade altered areas that reflected permanent change, namely along the Rio Grande. It was agreed upon initially between the NRCS and USGS that this would be the process. The resolution of all linework was completed in accordance with the National Standards for Spatial Data Accuracy (NSSDA). All 1:24,000 meter scale linework was generated digitally on screen inside of Arcmap. The initial scope of work divided the state into 6 areas for interim delivery to NRCS for review. NRCS in turn would post for in state coordinating agencies review for a pre-determined period of time. Comments on suggested edits were provided back to USGS for inclusion into the dataset after compilation and acceptance by NRCS. 2005-01-01T00:00:00 Edgematching with Arizona and Utah was straight forward as those datasets are stable. At this time there was no data to edgematch with across the Mexico border. Oklahoma was coordinated with and provided their dataset which was mostly complete. Texas also provided their dataset and agreed at some juncture to extend the linework shown on the New Mexico side of the border, where the Texas portion was above the acceptable size limit for subdivision. Colorado is edgematched as closely as possible at this time. It is assumed that Colorado will dissolve out small polygons, and estimations were made as to where those would best be implemented in order to edgematch as best as possible the linework and attribution across the border. Colorado borders are not currently being work on. 2005-01-01T00:00:00 Upon completion of all linework, attribution was performed statewide on the dataset by USGS in Utah, and delivered to NRCS for review and comment. Comments have been addressed and incorporated. 2005-01-01T00:00:00 First draft of metadata created by kjones using FGDCMETA.AML ver. 1.2 05/14/98 on ARC/INFO data set h:\wbd\edgematching_shapefiles\final\metadata\nm\nm_hu12_geo83 2005-08-11T00:00:00 Edits provided by NRCS to alleviate duplicate HUC12 coding. 2007-07-01T00:00:00 Edits provided by USGS Water Science Center, Salt Lake City, to edgematch with Mexico. 2009-02-01T00:00:00 Edits provided by USGS Water Science Center, Salt Lake City, to correct Downstream coding. 2009-08-01T00:00:00 Edit sent to AZ state office by Arizona Water Science Center, USGS, to correct HUC12 Downstream code; confirmed by New Mexico state office. 2010-01-11T00:00:00 Updates by USGS Water Science Center, Salt Lake City, Utah.
