Watershed Assessment, Tracking & Environmental ResultS

Reach Address Database (RAD) Download

Description

The RAD contains the spatial representation for each Water Program Feature and an associated identifier (also, known as the source_featureid) used to relate the spatial representation to descriptive attributes stored in a separate Water Program database. For example, the Assessed Waters Feature identifier can be used to access attribute information stored in the Assessment and TMDL Tracking and ImplentatioN System (ATTAINS). The RAD data downloaded from this page are delivered in zipped (compressed), shapefile format. Links to metadata (PDF and XML formats) for each set of Water Program Features in the RAD are also provided.

Please note, due to a flaw in the ArcIMS product (reference #NIM039848), the extracted RAD records with date fields containing a NULL values store a sequence of control characters in that record in the shapefile. These control characters may be troublesome to GIS clients seeking to use the shapefiles. To work around this problem, the RAD Download services have been altered to assign a "fictitious" date value of 02/29/1904 to any date which normally is empty. Fields affected are EVENTDATE, REACHSMDATE, END_DATE and START_DATE. Please consider any instances of the date 02/29/1904 to be equal to NULL.
