Utah HUC Boundaries

This data set is a subset of the complete digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the State of Utah. The State Watershed Boundary (WBD) was dissolved to the 8 digit, 4th level sub-basin. The State WBD 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. Data downloaded from USDA on 8/14/2017.
