During which season are the water levels on Lake Ontario at their highest?

The water levels on Lake Ontario typically reach their highest point during the spring season. This phenomenon occurs primarily due to the melting of snow and ice in the surrounding watersheds along with increased rainfall that often accompanies the season. As temperatures rise, the runoff from snowmelt flows into the lake, contributing significantly to elevated water levels.

While summer may see consistent water levels, it is not the time when levels peak. Autumn generally experiences a gradual decline in water levels as evaporation increases, and winter sees lower levels due to freezing conditions and reduced inflow. Understanding these seasonal variations is crucial for managing water resources and making informed decisions related to navigation, ecology, and flood control in the region.
