Local conservation authorities keeping an eye on erosion

More about erosion issues along the bluffs along some parts of Lake Huron.

This week, both the Ausable Bayfield and Maitland Valley Conservation Authorities warned about erosion issues.

Geoff Cade is the Ausable Bayfield Water and Planning Manager and says high water levels are part of the problem.

“With the loss at the bottom the bank gets steeper and then the top wants to get back to a stable angle and it starts to slough off. And in the spring that becomes a concern for people because we've got saturated ground and water getting off the landscape with the snow and so forth,” said Cade.

Cade says the bluff may look as stable as it did last year when people were at their cottages, but that could just be a shelf that's hanging at the top.

Meanwhile Maitland Valley Communications Coordinator, Jayne Thompson, says they have some areas in Ashfield-Colborne-Wawanosh that they're watching quite carefully right now.

"We've been in contact with the municipalities and it's just the nature of those steep bluffs that we have in our section of the shore line that they are always eroding,” said Thompson.

She adds when the bluffs are as saturated as they are now, it just makes it a little riskier and they are more prone to failure.
