Great Lakes Commission releases report detailing 2015 uses of Great Lakes waters

For immediate release: December 8, 2016

Ann Arbor, Mich. – According to water use data released today by the Great Lakes Commission (GLC), 42.7 billion gallons of water were withdrawn per day in 2015 from the Great Lakes-St. Lawrence River basin for purposes such as power plant cooling, public water supply, agricultural irrigation and industrial use. This data is included in the 2015 Annual Report of the Great Lakes Regional Water Use Database, which provides information on withdrawals, diversions and consumptive uses of Great Lakes-St. Lawrence River water.

Annual water use reporting by the Great Lakes-St. Lawrence River states and provinces began as a result of the Great Lakes Charter of 1985. The states and provinces committed to developing consistent information on water use to improve decision-making and support water management, conservation and efficiency programs. They report annual water use information to a regional database, which is maintained by the GLC in its role of managing and delivering regional information to support the conservation and balanced use of the Great Lakes.

The 2015 report, along with past years’ reports, are available at
