Does anyone know where I can find Stream (rivers, waterbodies) codes for the State of Utah?
Unique identifier for a ‘reach’. The first eight numbers are the WBD_HUC8. The next six numbers are randomly assigned, sequential numbers that are unique within a HUC8, 14-char value
In theory you should be able to do this all via http using published map services. However, I get a 404 when I copy and paste the geometry returned by this query for Utah ..
... into the filter geometry textbox of the NHD's mapservice and click Query (POST). It even happens when
Return Count only set to true, and everything else false.
You could also download the NHD data for your state, open the Feature Classes of the FGD in ArcMap/ArcCatalog, and open the attribute table and look them up by whatever attribute you are using, i.e. Feature Name, Reach Code, etc. NHD High Resolution by State FTP
