These data show the river nutrient regions in the State of Minnesota. Water quality standards for river eutrophication are applied to stream water units based on their relationship to these regions, though the nature of that relationship may not be as direct as a spatial intersect. Users should NOT rely solely on this dataset to determine the standard applicable to a specific waterbody. The standards, as applied, incorporate a downstream distance decay allowance. Thus, a stream flowing from the north to the central region retains the north region's standard as water moves into the central region for a distance determined by MPCA surface water scientists. In addition, there area several places in the state with reach specific criteria. For a detailed view of the standards applicable to a specific reach, please see the related dataset: river_nutrient_standards_wids |
