Updated freshwater assessment GIS package

We repackaged the Arizona freshwater dataset as a set of ArcGIS layer files, allowing you to easily load the entire dataset at once. Additionally, we have added additional streams, updated the flow status layer, and added a new Wild and Scenic river designation layer.

Arizona river flow status

Arizona river flow status is one of the datasets available in our freshwater GIS dataset. Click map to enlarge

The freshwater assessment contains four primary datasets:

  1. Habitat for 33 native fish species
  2. Former and current perennial surface flow for Arizona’s rivers
  3. The distribution of threatened and endangered species (ESA) that require aquatic or riparian habitat
  4. Wild and Scenic River designations

If you do not have ArcGIS software, we have also provided a Google Earth KML file, which can be viewed using the free Google Earth software.
