Index values are based on a variety of data sources, calculations Forest and scientific approaches. Each index is scored on a scale from 0 to 100, with 0 being Grassland Long Prairie River Rum River the least desirable result or condtion to 100 being the best existing condition or most Pasture/Hay Pomme de Terre River desirable result. Major watershed scale rankings may mask the range of conditions Cultivated Crops Chippewa River that occur at more local scales. A high score may indicate the least impacted condition Wetlands 0 42Miles Miss R-Sartell in Minnesota, not necessarily a healthy condition.

This gives comparatively high scores for outstate Minnesota. Viewing input data is necessary to evaluate possible watershed scale concerns. November, 2011.
