WATERS Geospatial Data Downloads

Description

Geospatial data for EPA's Office of Water Programs 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 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 WATERS 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 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.

| Metadata | Metadata is located at data.govExit EPA’s website, the United States government's open data website. |
| Additional Information | This dataset provides information about the conditions of the nation’s surface waters. States, territories and authorized tribes (states for brevity) assess the quality of their surface waters and report it to EPA as part of their Integrated Report, which combines Clean Water Act Sections 303(d) and 305(b). This dataset provides the spatial locations of state-defined Assessment Units and Assessment decisions for those waters. Designated Use and assessed Parameter information have been rolled up into groups. This dataset also includes attributes indicating the Assessment Units that have one or more Actions (a.k.a., Plans, such as Total Maximum Daily Load (TMDL), Alternative Restoration Plans, Protection Plans, etc.) associated with the water. For more information, please see https://www.epa.gov/waterdata/attains. This dataset provides the latest information submitted to EPA for each state. States typically provide this data to EPA every two years, but the currency of the data may vary by state. The Control table indicates the latest data available for each state. This dataset replaces the separate Pre-2015 geospatial datasets for CWA Section 303(d), 305(b), and TMDLs. |
