DULUTH, Minn.
Lake Superior's late-autumn water levels are at their lowest in 80 years, sparking concerns that the rapid fall of the world's largest freshwater lake could hurt shipping, shorelines and fish populations.
The drop in levels is due mainly to six months of regional drought, experts say. But the affects could last years, and continued dry conditions could exacerbate problems further.
In the shipping business, a major economic force in Duluth and the region, lower water levels mean the freighters that carry iron ore, coal and limestone must take on lighter loads in order to navigate through locks, channels and harbors.
