About Our Lake
Our Lake & Watershed

The Lake Simcoe Watershed is an area surrounding Lake Simcoe and its 35 tributary rivers and streams. It extends from the Oak Ridges Moraine in the south to Oro Moraine the north.

Lake Simcoe is the largest lake in Ontario after the Great Lakes, and is less than one hour away from 50% of the population in Ontario.

Lake Simcoe is a critical economic driver for many of the communities surrounding it -- generating over $200 million per year in recreational spending. In addition, many of these communities and other residents rely on the Lake for their drinking water, and the Lake is also used to assimilate industrial and human waste.

Currently, there is significant growth in industry and population planned for the land area around the Lake that will put even more pressure on the fragile ecosystem of the Lake Simcoe Watershed.
