Description

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.
