Muskoka’s watersheds stand at a crucial turning point. While currently healthy, they are gradually degrading in several ways, and our existing management systems seem incapable of halting or reversing this negative trend. We need an integrated, watershed-scale management system capable of dealing with the multiple stresses our iconic environment now faces.
About the Muskoka Report Card
The Muskoka Watershed Report Card, produced every five years by the Muskoka Watershed Council, scientifically assesses Muskoka’s watershed health. It educates residents and decision-makers about water and land conditions, enabling sustainable practices to bolster the strength of our remarkable natural environment. This is essential for our way of life and economy.
This summary Report Card below captures key highlights. Read the full Background Report for in-depth insights.
What is Watershed Health?
A watershed is a living and intricate ecosystem capable of maintaining its structure and functions unless faced with excessive stresses. Its health, or ecological integrity, signifies how effectively it preserves its typical structure and functions. Similar to how medical experts gauge human health, we measure watershed health by analyzing diverse indicators.
Muskoka’s Watersheds
This Report Card covers the entire Muskoka River Watershed (in blue), as well as a small portion of the South Georgian Bay Shoreline (in red) and parts of the Severn River-Lake Simcoe Watershed (in green) that intersect with the District of Muskoka. This vast 7,000 km2 area spans over 210 km from the Algonquin Highlands to Georgian Bay, including approximately 2,000 lakes amid extensive forests.
