2 Watershed Health Report - Major Watershed Average Watershed Health Score - National Land Cover Open Water Developed, Open Developed, Low Developed, Medium Developed, High Barren Land Decidious Forest Evergreen Forest Mixed Forest Shrub/Scrub Grassland Pasture/Hay Cultivated Crops Woody Wetlands Herbaceous Wetlands These health scores are calculated at the Major Watershed (HUC8) scale. Health score names followed by (*) are also calculated at the DNR Catchment scale (subdivided HUC12). Those results are reported on the following pages. Hydrology Geomorphology Biology Connectivity Perennial Cover* Impervious Cover* Water Withdrawal* Flow Variability Hydrologic Storage 61 Soil Erosion Potential* Terrestrial Habitat Quality* Groundwater Susceptibility Altered Streams* Surface Storage 48 Climate Vulnerability Sub-Scores Watershed Health Assessment Framework Health score methodology - Stream Species Quality* 65 At-Risk Species Richness 31 Species Richness Terrestrial Habitat Connectivity 6 Aquatic Connectivity* Riparian Connectivity* Water Quality Non-Point Pollution Sources Phosphorus Risk* Sub-Score Localized Pollution Sources* Assessments 36 September, 215
