The Watershed Health Assessment Framework (WHAF) provides an organized approach for exploring the complexity of natural and human systems. A 'Use Case' uses the Map to show an important concept with an example and instructions for you to follow.
Map and Share Your Watershed Boundaries
CONCEPT: Spatial Scale
Watershed boundaries are a challenge to understand and even more difficult to visualize or map.. until now! With WHAF's predefined boundaries and symbols you can display different watershed boundaries across spatial scales for any catchment in Minnesota in just 3 clicks of the mouse.
Step 1: Click here to open this map in a new browser window.
Step 2: Click on 'set location' tool . It will turn orange when it is 'on'.
Step 3: Click on your location of interest within Minnesota.
That's it! Now you are viewing the different watershed boundaries for your location. Here are what the different boundaries mean:
- Pink outline: Local catchment that sends surface water to the point you selected.
- Light blue fill: All catchments upstream of your location.
- Surface water flows from this area into your catchment. This is your 'true' watershed.
- If the pink outline and light blue fill cover the same area, this is a 'headwater' catchment. Surface water flows out, but not into, the catchment.
- White outline: Major watershed boundary
- This boundary is used for managing resources and working with partners. It might be the upstream true watershed, or it might be an artificial subdivision of a larger watershed. This is your 'administrative' watershed.
- Dark blue fill: Catchments downstream of your location.
- Mask: Major river basin for the large river system connected to your location.

There are ways to change the map to meet your needs. Check out 'Map Help' for instructions to:
- Change the background map.
- Use gray scale buttons (top right) to change symbology for outline, fill and mask.
- Zoom in or out.
- Create URL link to your map.
- Email the URL to a collegue so they can click and open your map.
- Add a bookmark.
- Re-open the same map view.
