WATERS Geospatial Data Downloads
Description
Geospatial data for EPA's Office of Water Programs, including 303(d) Impaired Waters, 305(b) Waters As Assessed and Total Maximum Daily Loads (TMDLs) are available as prepackaged national downloads or as more current GIS web and and data services. EPA provides WATERS geospatial data in a variety of formats including Geographical Information Systems (GIS) compatible shapefiles and geodatabases, as well as ESRI and OGC web mapping services.
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 be indexed to NHDPlus reached hydrography. 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.
