We deliver sound scientific research and solutions supporting water levels, water quality, wetlands, the fishery, and aquatic invasive species control.


Water Levels

Now the most valuable commodity in the world and we have 20% of the world’s freshwater in the Great Lakes. But it is a glacial deposit and only 1% is renewable. And in periods of declining water levels there have been significant concerns over water quality – increased nutrient concentrations leading to toxic blue green algal blooms. [READ MORE]


The most important element in aquatic ecosystems. Georgian Bay has the highest quality, most diverse, most extensive wetlands found anywhere in the Great Lakes. But our wetlands are the most sensitive to sustained low water levels since they are on glacial till sediments scattered among the 30,000 granite islands on Georgian Bay. [READ MORE]

Grass Carp

Grass Carp, with their voracious appetites … pose a serious threat to waterfowl habitat and wetlands. It is currently estimated that, unless Grass Carp are eradicated immediately, they will quickly colonize the middle and lower Great Lakes and destroy the wetlands. [READ MORE]

Webinar: “Extreme Water Levels on the Upper Great Lakes: What Can Be Done?”

p>Roger Gauthier will present facts about the current high-water crisis on the Upper Great Lakes, including detailed background on historic changes to the system. He will be assisted by Mary Muter for a detailed question and answer session.

Topics will include information on why water levels are so high, what actions need to be implemented to reduce shoreline damages this year and what to expect over the next few years.

The purpose of these webinars is to outline the problem and offer solutions.

Tues. May 12, 2020 at 7:00 PM.

Grass Carp lurk where politics muddies the waters

Grass Carp lurk where politics muddies the waters

By Kate Harries, Springwater News, Feb 20/2020 There's a chance that one of the greatest threats to the health of the Great Lakes can be turned back, the Wasaga Beach Men's Probus Club heard last week. But progress towards stopping a Grass Carp invasion has been...

About Our Foundation

Where are we?

In the fall of 2016, we joined the Huronia Community Foundation(HCF), a well-funded, highly respected charity based in Midland, Ontario on the south shore of Georgian Bay.

What do we stand for?

Our dedicated team of eight experienced, knowledgeable passionate volunteers will continue to work, as it has for many years under other charities, to protect and enhance the environment of Georgian Bay as part of the Great Lakes’ ecology.

Our Successes

It was our team’s investigation of the St. Clair River that inspired the 2004 Baird Report. It led to the inclusion of the St. Clair River in the International Upper Great Lakes Study.

Current Priorities

We will continue and endeavour to expand our visits to Ottawa and Washington, D.C., in order to ensure that key elected officials and government agencies receive accurate, up-to-date information on Great Lakes issues, particularly those impacting Lakes Michigan-Huron and Georgian Bay.

We Have the Power to Impact Our Future, and We’re Doing Something About It

Although almost all of our work is undertaken by volunteers, the Georgian Bay Great Lakes Foundation has major expenses for our scientific research and education program around all the Great Lakes and minor expenses for admnistration and for travel to meetings with key officials and shoreline property owners’ groups.

When you give, almost 100% goes to support our cause!

Our administration expenses are very low – a very modest amount to the Huronia Community Foundation, and a similarly modest amount for the work of our professional communications expert and our website.

We are deeply grateful for your past generosity and support for our work and urge you to help us bring these endeavours to a successful conclusion.


We held a Science Sumposium in November 2019 at the McMichael Canadian Art Collection.

Our Top Priorities

Water Levels

We have engaged W.F. Baird & Associates to begin a study to model water levels on Lakes Michigan-Huron in the light of historical water level cycles and the change in conveyance capacity of the St. Clair River.

Education on Carp Threat

We will continue to participate in national and international meetings on the threat of entry into the Great Lakes of destructive invasive species of Carp.


Support wetlands researchers from Environment Canada, and support research of Prof. Pat Chow-Fraser of McMaster University on wetlands, fish productivity, water quality, and the survival of threatened species such as Blandings Turtles. 

Education of Elected Officials & Government Agencies

We will continue and endeavour to expand our visits to Ottawa and Washington, D.C., in order to ensure that key elected officials and government agencies receive accurate, up-to-date information on Great Lakes issues, particularly those impacting Lakes Michigan-Huron and Georgian Bay.
