Water: Data

WATERS Program Data


GIS from the Reach Address Database (RAD) must be joined/linked to corresponding program attributes using the below "Relational Key" information. The relational key for the RAD features is either source_featureid alone or a combination of source_originator, source_featureid and start_date/cycle_year.




Example of how to Join Reach Address Database GIS Datafiles and Attribute Table Data

To join 303(d) program attribute information to the Listed As Impaired Waters events

  1. Download the Listed Impaired Waters event GIS datafile for a given state from the RAD download page.
  2. Download the corresponding Listed Impaired Waters (303(d)) attribute information from the WATERS Expert Query Tool in either a comma separated file (.CSV) or a tab delimited file (.TAB).
  3. Take both the event shapefile and the attribute database file into a GIS software package such as ArcGIS Desktop, and link the attribute information to the GIS datafile using the LIST_ID field (see "Relational Keys" field in the table below for the correct field to use for other programs) in the attribute information table and the source_featureid field in the GIS datafile.
