Great Lake's levels sink - Record lows likely to hit shipping & recreaton

Lake Superior water levels are headed toward record lows in early fall, a projection that is causing concern about an eventual trickle-down effect in the other Great Lakes as well as Lake St. Clair.

The U.S. Army Corps of Engineers' June forecast -- looking ahead to September and October -- predicts Superior's water level will dip under the record low for that time of the year. That low was set in 1925.
