To evaluate the factors behind this decline, the scientists examined water level data for Lakes Michigan and Huron from 1860 to 2006, including precipitation, evaporation and runoff data. The results reveal an underlying gradual decline in water levels since 1973. This underlying drop may be due to an increase in evaporation levels, they say.
We cannot be certain that the present observed water level drop is caused by factors related to global climate change, or that it portends a long-term problem, the study states. But the ongoing decline in water levels make it prudent to include lower lake levels in future management planning, the researchers note.
