Muskoka Watershed 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.
Muskoka Watershed Report Cards have been released in 2004, 2007, 2010, 2014, 2018 and 2023.

2023 Muskoka Watershed Report Card
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.
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.

2009 Progress Report Card
The principal objective of the 2007 Watershed Report Card was to evaluate changes in ecosystem condition and the impact of human actions against a standard of a healthy, functioning and sustainable watershed. Achieving this objective is a shared responsibility of everyone who lives within the watershed.
The 2009 Progress Report Card explored new programs and actions that have been taken by municipalities to move toward the long-term goal of sustainability. Although municipal action is only one component of the overall equation, there is no doubt that our municipal governments can, and do, take a lead role by their example and by implementing policies and regulations that support a more sustainable approach to development and community activities.
2007 Muskoka Watershed Report Card
The 2007 Watershed Report Card was released on July 27, 2007 at Partners Hall in the Algonquin Theatre in Huntsville.
The objective of the 2007 Watershed Report Card was to evaluate changes in ecosystem condition and the impact of human actions against a standard of a healthy functioning ecosystem. A review of existing data on the health of our water, air and land forms the basis upon which the 2007 Watershed Report Card was developed.

2004 Muskoka Watershed Report Card
MWC released its first Report Card of Watershed Health on Thursday, July 8, 2004 at Annie Williams Park in Bracebridge.
MWC worked closely with several provincial and federal departments to accumulate and analyze environmental data for Muskoka and were pleased with the results of the 2004 Report Card. It was used to guide MWC’s projects and programs for the follow several years.
