We know that the extensive pre-settlement logging of the Great Lakes drainage basin affected water quality, as indicated by sediment evidence of increased phosphorus concentrations (Kemp et al. 1972) and diatom production (Stoermer et al. 1985; Schelske et al. 1988), and model predictions of increased phosphorus loading (Chapra 1977). However, we don’t know the magnitude of land affected by more recent clearcutting, nor its effects on water resources. The purpose of this report is to describe these land use changes and other characteristics of the Minnesota North Shore drainage basin that could potentially affect fluxes of sediment and nutrients into Lake Superior.enNorth Shore drainage basinLake SuperiorMinnesotaNonpoint source pollutionLand useDeforestationNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
