The 12 month outlook summary for the Great Lakes in English units.
Georgian Bay, Lake Huron and Lake Michigan are connected hydrologically. Historically the water levels have fluctuated somewhere around 6 feet in periods of time that span years. Fluctuations are important and necessary to our native plants and animals that have evolved and adapted to historic conditions in the upper Great Lakes. The competitive success of those plants at their favourite water levels ensure that there are a variety of plants that can provide shelter, protection and food for the large number of species that call these wetlands home. Climate change has disrupted these relationships, and impacted our own recreational activities in Georgian Bay.
What is the water level forecast for the next five years? Increasing variability and flashiness with a slight trend to higher average levels and wider range between highs and lows. (as of December 2020)
