Indicator Data and Metadata
We recommend that you obtain data from WSIO by creating and downloading a custom WSIO Tool, but you can also download just the indicator data for an EPA Region of your choice from the WSIO Indicator Data Library page. The data include measurements of ecological, stressor, and social characteristics compiled for roughly 83,000 small (HUC12 scale) watersheds across the conterminous United States.
From the WSIO Indicator Data Library page, you can also open the WSIO indicator library metadata file and review indicator types and descriptions, which can be a useful planning step before selecting indicators while creating the tool. The page also includes water mask, hydrologically-connected zone, riparian zone, and wetness index datasets.
These documents provide general and specific directions on how to open the WSIO Tool online, select a geographic area, choose indicators, do comparative watershed assessments, and save the analyses.
