This map shows NetMap's existing coverage of virtual watersheds. If you do not see your watershed of interest, contact us
to build it for you. NetMap can be developed and delivered anywhere in the United States, including Alaska and Hawaii.
From this page, you can freely download NetMap's mini virtual watershed & synthetic stream layer with attributes. See what is included.
Full NetMap Virtual Watersheds are designed to work with NetMap tools (an Add-In in ArcMap 10.x). Get the Datasets bundled with the tools; access NetMap datasets + Analysis Tools. Don't see what you need, we build new datasets.
Compatibility with NHD/NHDplus (coming soon, 2015).
