Information on high lake levels

Erosion and bluff instability are two of the impacts of high lake levels.


Information sources about high lake levels

Lake Huron water levels are of interest to property owners along or near the shoreline and to people who visit Lake Huron.

The impacts of high water levels include erosion and unstable bluffs.

How can you find out more about water levels?

There are several sources of national and local information related to high water levels and their impacts.

Canada has a newsletter that provides a monthly update, on Great Lakes and St. Lawrence River water levels, LEVELnews, at this link:

Ausable Bayfield Conservation Authority (ABCA) issues Shoreline Conditions Statements, to local municipalities, when warranted. These statements are issued when weather forecasts over Lake Huron suggest a potential for high waves reaching the shoreline and resulting in potential coastal flooding and erosion issues. These messages, in addition to flood messages, are also posted on the website at this link:

The Shoreline Conditions Statements are also posted on Ausable Bayfield Conservation's social media channels (Facebook and Twitter).

Ausable Bayfield Conservation Authority has resources, (including the Shoreline Slope Stability Risks and Hazards Fact Sheet for Property Owners, by Terraprobe Inc.) on its website. The conservation authority, and its partners in the Healthy Lake Huron – Clean Water, Clean Beaches Partnership, are adding materials – this summer and autumn – related to water levels; water level impacts; and best practices residents can consider. These resources are to include a new fact sheet about what vegetation to plant along the shoreline.

The conservation authority wants to help the public become aware of, and to navigate, the different sources of information related to lake levels; their impacts; and best practices. “The high lake levels are a concern to us and to property owners and we want to do what we can to connect people to current information from the relevant authorities and to helpful information to deal with the impacts of high water levels,” said Geoffrey Cade, ABCA Water and Planning Manager.
