added about water decline
Because of the large size of the lakes many of the larger cities experience lake effect snow, where westerly winds capture moisture over the unfrozen lakes and when cooled over the land, heavy snows can fall. Additionally the lakes can moderate the warm temperatures in the summer, and release the heat in the fall.
== Decline in Water Levels ==
"Government forecasters are projecting that Lake Superior, the largest of the five, will fall to its lowest level for September since modern recordkeeping began nearly a century ago."<ref>http://www.theglobeandmail.com/servlet/story/RTGAM.20070924.wlakes24/BNStory/National/</ref>
