WAT Score
The Watershed Assessment Tool measures five components of watershed health. These components are: Hydrology, Geomorphology, Biology, Connectivity and Water Quality. Each component contains 3-5 health index scores. The index scores are combined to create a component score. The component scores are also combined into an overall mean (average) watershed health score; and the index identified with lowest score is the watershed minimum health score.
