Abstract This data set is a complete digital hydrologic unit boundary layer to the watershed (10-digit) 10th level for the State of New Mexico. 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.
Purpose 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.
Data Set Credit 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.

Data Quality Information

Attribute Accuracy Report
Report 100% of the attributes were visually verified using 24K digital raster graphics (DRG's). The accuracy of this data is dependent on the level of detail of the source material and the interpretation procedures for capturing that source.

Horizontal Positional Accuracy Report
Report The New Mexico WBD was produced using Digital Raster Graphics (DRG's) as the source map. Data completeness for DRG files reflects content of the source graphic and may therefore be reflected in the completeness and accuracy of the WBD. The map was digitized from USGS 1:24,000-scale digital raster graphic base maps, with an inherited error of +/- 40 feet according to the USGS National Map Accuracy Standards. It is estimated that any errors detected were less than 10%. It should also be noted that while general rules of hydrology were used (i.e. natural water flow is downhill), the locations of boundaries is still somewhat subjective as the 1:24,000-scale DRG's do not always provide enough information for identifying the location of the boundaries.

Logical Consistency Report There are no unclosed polygons, intersections without nodes, or polygons without labels or with more than one label. 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.
Completeness Report All fields for all polygons in the .pat are attributed. Some polygons in the Ncontrb_a field might have a 0 value. All fields for the lines in the .aat are attributed. The lines adjacent to the universal polygon are attributed with a 0 for the hu_level. These cannot be attributed until the adjacent states complete their linework at which point the highest level of hydrologic unit can be determined.

Process Description 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.

Process Description 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.
