2018 Muskoka Watershed Report Card

The Muskoka Watershed Report Card is a science-based evaluation of the health of our watershed using a variety of environmental ‘health’ and ‘threat’ indicators. Health indicators include phosphorus and calcium concentrations in lakes, benthic macroinvertebrates, and interior forest habitat. Threat indicators include climate change, invasive species, fragmentation, and species at risk. Together, these indicators provide a “snapshot” of watershed health and serve to increase our understanding of the watershed where we live, work, and play.

Each of Muskoka’s 19 subwatersheds has been graded as ‘not stressed’, ‘vulnerable’ or ‘stressed’ for each indicator.
