Currently, only Lakes Superior and Ontario are regulated by structures, Mackey explained. Water level changes are driven by long-term factors such as precipitation, evaporation, inflows and outflows, diversions, and consumptive uses; and short-term factors such as wind and storm events.
Can the water level of the Great Lakes be controlled?
Generally, regulatory changes require approval by the International Joint Commission. Changes in water levels of the Great Lakes from diversions and control works require a significant amount of time to take effect due to the amount of surface area of this lake system.
Who controls the level of the Great Lakes?
The Great Lakes water levels currently are controlled by several factors, including the Soo Locks, which regulate the outflow from Lake Superior, and five diversions that transfer water in and out of the Great Lakes basin, including the Welland Canal, which connects lakes Erie and Ontario.
What are the main factors controlling the water level of the Great Lakes?
Water level (the height of the lake surface above sea level) is influenced by many factors, including precipitation, snowmelt runoff, drought, evaporation rates, and people withdrawing water for multiple uses. Water temperature is influenced by many factors, too, but most directly by air temperature.

Why is Lake Michigan losing so much water?
Dry weather is the cause of the fast lake level decline. The lack of precipitation this winter, spring and early summer was the cause. Kompoltowicz reminds us the biggest drivers of water levels on the Great Lakes are precipitation, evaporation and runoff.

All the Great Lake water levels remain above their long-term average. Except for Lake Superior, all the Great Lakes are expected to remain above their long-term averages for the next five years.
Is Lake Michigan growing?
Lake Michigan’s water level has historically risen or fallen by just a matter of inches over the course of a year, swelling in summer following the spring snowmelt and falling off in winter.
