Restoring the Health of Lake Simcoe

A new strategy to reduce phosphorus levels in Lake Simcoe by almost 40 per cent will help ensure the long-term protection of the lake, watershed and ecosystem.

Phosphorus helps plants in the lake grow, but having too much of it leads to excessive plant growth and a depletion of the oxygen levels that the lake's fish need to thrive.  Reducing phosphorus from 72 to 44 tonnes per year will improve water quality and protect the coldwater fish community. 

The phosphorus reduction strategy is a key part of the Lake Simcoe Protection Plan, which marked its first anniversary in June.  This plan, the first of its kind in Ontario to address environmental protection of a watershed, provides a roadmap to help restore and protect the health of the lake and its watershed.
