Here's a blog posting from 2007.
Well here we are in 2012, with a warming climate that is evaporating off even more water and a big study suggests that the solution is to...do nothing.
That idea was rejected in 2010, but apparently it's back.
Dan Egan has the story:
It long has been acknowledged that historic dredging and mining in the St. Clair River, the primary outflow for Lakes Michigan and Huron, permanently lowered the connected lakes by about 16 inches.
A recently completed $15 million study funded by the U.S. and Canadian governments found that unexpected erosion since a U.S. Army Corps of Engineers dredging project on the river in the early 1960s dropped the lakes' long-term average by as much as an additional five inches.
But that study, co-led by an Army Corps employee, concluded that the erosion is not ongoing and is therefore not triggering further water loss.
