Sand washing down the St. Clair River is acting as a slurry, restricting the flow from Lake Huron and Lake Michigan.
That could be one reason why the two middle lakes are reaching a “crisis high” condition, Mary Muter told the Wasaga Beach Men’s Probus Club during a presentation on Great Lakes water levels.
Muter, the chairperson of the Georgian Bay Great Lakes Foundation, and a former Georgian Bay Baykeeper, said the International Joint Commission needs to do more to control the flow going down the St. Clair, which she sees as one of the main factors behind the dramatic fall and rise of Huron and Michigan.
An image of the river from 2014 showed very little sand making its way through the system; three years later, the presence of sand is evident.
“It’s changing the river’s flow … it’s like pouring water, and then pouring thick soup,” she told club members.
