Why are Lake Michigan water levels rising?

Over the past decades, the water levels of the Great Lakes have undergone dramatic fluctuations, exhibiting a range exceeding 2 meters. These changes are due to climate-induced alterations in the three primary components of the lakes' water budget: over-lake precipitation, lake evaporation, and basin runoff.

Factors Affecting Lake Levels The primary driver of water levels are precipitation, evaporation, and river flow into the lakes, also referred to as net basin supply. The long term trend for both precipitation and evaporation has been upward over the last several decades.

These lake surface temperatures are projected to rise by as much as 7°F by 2050 and 12.1°F by 2100. Higher temperatures, increased precipitation, and lengthened growing seasons are likely to result in increased production of blue-green and toxic algae in the lakes.

Climatic conditions control precipitation (and thus groundwater recharge), runoff, and direct supply to the lakes as well as the rate of evaporation. These are the primary driving factors in determining water levels.

No. People are not capable of changing things on that scale. We could easily pollute the water and make it undrinkable, but we can't drain the lakes, because there is just too much water there, and it's constantly refilled from too many sources, including rain and snow melt.

Threats & Conservation The source of toxic pollutants includes decades of industrial waste, raw sewage overflows, runoff from cities, and mining operations. Excess nutrients that throw the ecosystem out of balance enter the lakes from agricultural runoff and untreated sewage.
