Why is Lake Michigan water level dropping?

In winter, the precipitation amounts decline in the colder air. A loss of water level basically comes down to more water flowing out and evaporating than falling as precipitation. Also, the precipitation is mostly snow in December, which doesn't make it as water into Lake Superior until the spring snowmelt.

Climate change's hotter temperatures and society's diversion of water have been shrinking the world's lakes by trillions of litres of water a year since the early 1990s. A close examination of nearly 2,000 of the world's largest lakes found they are losing about 21.5 trillion litres a year.

The net volume loss in natural lakes is largely attributable to climate warming, increasing evaporative demand, and human water consumption, whereas sedimentation dominates storage losses in reservoirs.

Swimmers didn't find it too appealing, but it was popular for those who wanted to fish for trout. However, an analysis of satellite images between 1998 and 2012 showed that Lake Michigan and Lake Huron are now clearer than Lake Superior, which had always been the clearest of the Great Lakes in the past.
