Water Resources in the Vicinity of Municipalities on the Central Mesabi Iron Range Northeastern Minnesota

Additional supplies of water are available near the municipalities on the central Mesabi Iron Range. Ground water presents the greatest potential yield, and most of the productive aquifers are in the Biwabik Iron-Formation and the stratified glacial drift. A single body of ice-contact stratified drift underlies parts of all but one of the five municipality areas mapped. Surface-water supplies are generally inadequate. The Two River system in the eastern part of the area of this report offers some possibilities. Flow data from one discharge station and one miscellaneous gaging site are presented. Analyses of water from many sources are presented as are data from many wells and test holes. Ground water commonly has a concentration of high iron and manganese and is hard. Surface water generally has a high concentration of iron and is colored.
