About the Framework

The Watershed Health Assessment Framework (WHAF) uses five components to view natural systems. Like looking through different colored lenses, each of the five components brings a different perspective.  This framework provides a consistent approach for exploring the complex landscapes that impact watershed health. 

A description of each component is followed by some important concepts to consider about each one. This background information is used to inform the health scores that were created for each component.
