Great Lakes


The Great Lakes Section of SCO started in 2010. It is led by veteran Great Lakes advocate Mary Muter and comprised of Sierra Club members with specific experience and focus on Great Lakes issues. They are addressing the multiple components of the Great Lakes ecosystem using bi-national coordination of activities with the Sierra Club in the States.

Sierra Club’s substantial body of work includes a leading role in the agreement of Great Lakes jurisdictions to ban new diversions of water out of the basin.

Current work includes focus on sponsoring wetland research by McMaster University, advocating for restoration of healthy water levels in the Middle Great Lakes (Huron, Michigan & Georgian Bay), and protecting the ecosystem from invasive exotic species like Asian Carp (sign the petition HERE).
