What is a Causation Study?
A Causation Study is a way to determine why the water quality of a lake may be vulnerable based on key criteria. Impacts to water quality may be due to natural processes or human activities, and determining which causes are affecting water quality is an essential step in protecting Muskoka’s lakes.
Why is the District of Muskoka undertaking Causation Studies now?
The District of Muskoka’s Official Plan Amendment 47 (OPA 47) was approved by the Province on June 28, 2019 and updated the District’s Lake System Health policies. A key component of these new policies involves the initiation of causation studies by the District for lakes considered to be vulnerable from a recreational water quality perspective.
What other lakes in Muskoka are scheduled for Causation Studies?
Upon completion of the Causation Study Pilot Project on Peninsula Lake, District of Muskoka staff have recommended that, pending funding and other resources, causation studies be undertaken for other vulnerable lakes, specifically Stewart Lake, Leonard Lake and Three Mile Lake over the next two years.
