What drives water levels is very complex, and a range of about 6 feet over time is not unusual. In fact, a range is important for the unique character and biodiversity of Georgian Bay as part of Lake Michigan-Huron. What is different is the new extremes that water levels seem to be reaching – the range appears to be expanding and more volatile. There’s a lot of information out there on water levels and what to do to take the edge off the increasing extreme high-highs and low-lows. It’s a challenge to know what information is best to act on. This symposium aims to bring together the experts, scientists and stakeholders, to drive consensus about what should be done.
