Canadian environmental sustainability indicators: En4-144/46-2017E-PDF

phosphorus levels in the offshore waters of the Great Lakes.

“This indicator reports total phosphorus levels in the offshore waters of the 4 Canadian Great Lakes. The indicator assumes water in the Great Lakes would never be above phosphorus water quality objectives in the absence of human development. It provides information on how human activity contributes to phosphorus levels in 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"--What does the indicator measure, p. 7.
