Phosphorus levels in the offshore waters of the Great Lakes

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Phosphorus levels in the offshore waters of the Great Lakes indicator reports total phosphorus levels in the offshore waters of the 4 Canadian Great Lakes. A lake's phosphorus status is determined by comparing spring total phosphorus levels to its water quality objectives and the health of the lake's food web. Failure to meet a water quality objective for phosphorus suggests a greater risk to the health of the lake ecosystems. Information is provided to Canadians in a number of formats including: static and interactive maps, charts and graphs, HTML and CSV data tables and downloadable reports. See the supplementary documentation for data sources and details on how those data were collected and how the indicator was calculated.
