Watershed Health Scores

Watershed Health Scores are calculated to show patterns of health within each of the five components for the state of Minnesota.  Using a consistent scale of 0 (least healthy/red) to 100 (best health/green), the health scores compare and contrast ecologically significance relationships across the state.
