Water resources in the vicinity of municipalities on the east-central Mesabi Iron Range, northeastern Minnesota

Additional supplies of water are available near the municipalities on the east-central Mesabi Iron Range. Both ground water and surface water offer good potential supplies. For the ground-water supplies, the most productive aquifers are the Biwabik Iron Formation and the stratified glacial drift. Surface-water supplies are variable. Streams in the western part of the report area are too small to yield supplies of importance, but lakes are a good potential supply. Eveleth and Gilbert are the only towns presently utilizing this source. In the eastern part of the area of this report, the Pike and Embarrass Rivers offer good potential supplies. Flow records from two gaging stations are presented as are data from many wells and test holes. Surface water generally has a high concentration of iron and is colored. Most ground water has a high concentration of iron and manganese and is hard. Analyses of water from many sources are presented.
