Two Great Lakes hit lowest water level on record

Measurements taken last month show Lake Huron and Lake Michigan have reached their lowest ebb since record keeping began in 1918, and the lakes could set additional records over the next few months, the corps said. The lakes were 29 inches below their long-term average and had declined 17 inches since January 2012.

The other Great Lakes — Superior, Erie and Ontario — were also well below average.

"We're in an extreme situation," said Keith Kompoltowicz, watershed hydrology chief for the corps district office in Detroit.
