State of Lake Ontario: Past, Present and Future

“This State of Lake Ontario volume reflects the breadth of scientific inquiry, the wealth of information on the past and present, and the future of this large ecosystem. The luxury of knowledge and understanding of the LakeOntario ecosystem speaks volumes to its uniqueness as a long term ecological site and, more importantly, as a barometer of ecological change globally.”

Ed Mills, Professor. Department of Natural Resources, Cornell University Biological Field Station.
