Lake Level Coherence Supports Common Driver

Authors


Abstract

Lake Superior, the world's largest lake by surface area (82,400 square kilometers), experienced record low water levels in 2007 [Holden, 2007]. In addition, lakes Michigan and Huron (58,000 and 59,596 square kilometers, respectively), which behave hydraulically as one lake and which began declining in 1997, were at near-record low levels in 2007 [Sellinger et al., 2008]. The low levels that these three lakes are experiencing have raised concern that the Laurentian Great Lakes are beginning to realize predicted climate change effects [Magnuson et al., 1997].
