Geospatial Data Downloads
Description
Geospatial data for EPA’s
Office of Water Programs, including 303(d) Impaired Waters, 305(b) Assessed Waters and Total Maximum Daily Loads (TMDLs) are available for download by state or watershed, as well as at a national extent. Generally, state-level geospatial data represents the most recent data submitted to EPA by states. EPA provides WATERS geospatial data in a variety of formats including Geographical Information Systems (GIS) compatible shapefiles and geodatabases, as well as both vector and raster keyhole markup language (KML) and KMZ files for
viewing WATERS data in Google Earth.
State and Watershed Geospatial Data
You may download the spatial files representing the most up-to-date
publicly available Water program data by State or Watershed from the Reach Address Database (RAD) download page.
National Geospatial Datasets
National geospatial datasets provided on this page are produced and periodically updated by EPA using state-submitted data.
These datasets are created based on information in the
Reach Address Database (RAD)
on the date of extract. To be included in this dataset states and other jurisdictions must have submitted information to the program database and
indexed
to the RAD. Due to the nature and complexity of providing a national snapshot of program data, EPA has provided a fact sheet to accompany and clarify the contents of each dataset.
