Surf Your Watershed

Surf Your Watershed (SYW) has provided simple access to a rich collection of watershed information since its release more than 20 years ago. SYW has recently been decommissioned because of technology migration and related security issues.

A replacement application is currently in development, with an expected released date of Fall 2018. How’s My Waterway?, Version 2, will incorporate much of SYW's content and expand relevant watershed information. Please watch this page for periodic updates on How’s My Waterway? Version 2.


During the interim period, the web sites listed below provide a wide variety of watershed related information:
  • River Network:
    • River Network is a nonprofit connecting nearly 6,000 water-focused organizations, agencies, businesses, and communities for greater local impact and healthier rivers across the U.S. Its project “Who is Protecting your Water?” will offer an interactive, searchable map of thousands of organizations, agencies, and indigenous communities protecting water across the U.S. This website performs a role similar to EPA’s former website Adopt Your Watershed.
  • How's My Waterway? Version 1.0: https://watersgeo.epa.gov/mywaterway/
    • This website offers a 10 by 10-mile search box through which users can learn the condition of local streams, lakes and other waters anywhere in the US in plain language, and what’s being done. Map and list formats are available. Version 2.0 will replace this website later this year.
  • Watershed Index Online: https://www.epa.gov/wsio
    • This website provides online tools and data for viewing watershed characteristics within user-selected geographic areas anywhere in the conterminous United States.
  • Recovery Potential Screening: https://www.epa.gov/rps
    • This website provides comparative watershed indicators, assessment methods and example projects as well as a full national set of state-specific watershed comparison tools that use the Watershed Index Online datasets.
  • Healthy Watersheds Protection: https://www.epa.gov/hwp
    • This website covers protection projects and analysis methods for protecting aquatic systems via landscape approaches. Included in this site is a preliminary assessment of watershed health in each of the 48 conterminous states.
  • WATERS GeoViewer: https://www.epa.gov/waterdata/waters-geoviewer
    • Simple access to stream network search for water information as well as watershed delineation and associated landscape attributes.
