Welcome to the Freshwater Network

This network provides scientific information to support decision making about freshwater resources in a user-friendly, online mapping system. You can interact with complex scientific data about the status and trends of freshwater resources, use ready-made decision support tools, or create your own, unique tools to meet your needs. From catchments, to watersheds, and even state-wide scales, you have access to a wealth of information about water resources and watersheds.

  • Perform Robust Analyses and Run Models to Explore:

  • Watershed Health and Landscape Integrity
  • Water Quality
  • Surface Flow
  • Fish Communities
  • Coastal Connectivity

Watersheds don’t follow political boundaries, so this network allows you to investigate across states and even into the coastal zone to understand the connectivity of our freshwater and coastal resources. We hope you find the Freshwater Network to be a powerful and user-friendly resource to understand the health of your watershed and ensure a healthy supply of clean water for nature and people.

Mission Statement

The mission of the Freshwater Network is to provide powerful spatial decision support tools that put scientific information in the hands of public agencies, communities, decision-makers, and the general public.
