Georgian Bay's Current Water Levels
Oct 2016: La Niña is no longer expected to develop. Here is the latest October 12 month Outlook including a longer text summary. Click here.
Summer 2016:Georgian Bay water levels are modestly above average in Lake Huron-Michigan thanks largely to conditions from a strong El Niño. Warmer air temperatures and warmer water temperatures resulted in less evaporation (note: evaporation increases with greater contrasts in air and water temp). El Niño is weakening, and NOAA is predicting (50% probability) that the Great Lakes may be influenced by La Niña conditions by late fall. Georgian Bay water levels are generally expected to stay above average, but may decline with the cooler weather of La Niña in late Fall. .

- Lake Huron-Michigan water levels go up and down for a variety of reasons.
- However, climatologists project with high probability that water level lows will continue to dip beyond norms, and that flashier highs may be a possibility. Learn more: Extreme Fluctuations in Water Levels
- Since the 1960s the single biggest cause of extreme water level highs and lows has been climate change. Learn more: Climate Change Impacts
- Without some kind of intervention now, we will experience more severe lows in coming decades than we have ever seen before. Learn more: Managing Water Levels in the Great Lakes: The Search for New Solutions
- Such drastic lows will not only impact our economy but our way of life as we know it today. Learn more: Low Water Levels, the Economic Impact of Doing Nothing
- Bottom line is we need to find new and better ways to stabilize water levels for the long-term health and well-being of the region. Learn more: Managing Water Levels in the Great Lakes: The Search for New Solutions
