The Watershed Health Assessment Framework (WHAF) is designed for exploration across spatial scales. DNR major watersheds and DNR catchments are used as a set of boundaries for calculating information about the health of the landscape. The calculations are used to create comparable health scores that reveal health trends and relationships at many scales.
The Watershed Health Assessments consist of health scores that rank the condition of Minnesota's watersheds from 0 (poor health condition, red) to 100 (good health condition, green). The index values are benchmarks, like blood pressure, heart rate or age; they show trends across the landscape that compare health condition and health risks.
Natural resource systems are summarized into five ecological components: biology, connectivity, hydrology, water quality and geomorphology. A number of different index scores are calculated for each component giving a multifaceted view of watershed health.
