The Muskoka Watershed Council mandate is to manage the streams, rivers, and
lakes in the Muskoka watersheds. The Council provides information and support to decision-makers, managers, and the general public on ways to protect and restore the resources of our
watersheds.
Information about their resources can be found on their website.
Muskoka Watershed Report Cards are an
evaluation of the health of the water, land, and wetlands in Muskoka. The report is broken down into the various watersheds. Ril Lake is located in the South Muskoka River
watershed.
