Lake Huron and Lake Michigan are at their lowest levels since record keeping began a century ago, but experts say it's too soon to tell exactly what combination of issues is causing the drop.
Water levels in Lake Huron and Lake Michigan are the lowest they’ve ever been since record keeping began in 1918, according to the US Army Corps of Engineers. That finding, which corresponds to a decade of diminished precipitation and higher temperatures, worries barging and commercial fishing interests, with both industries saying it will have harsh economic consequences.
The Corps reported this week that both lakes were 29 inches below their long-term average and that levels had declined 17 inches since January 2012 alone. The agency said the water levels have been below average for the past 14 years, which is the longest period of sustained below-average levels since 1918. Continued record lows are expected for the first few months of this year.
