Our Watershed

A watershed is an area of land that collects and drains rivers and streams into a body of water. Teeming with life, the Lake Simcoe watershed spans 3,400 square kilometers, and is one of the fastest growing regions in Canada.

Our Location

With a home office in Newmarket, we are one of 36 conservation authorities located in Ontario. Conservation authorities are mandated to ensure the conservation, restoration and responsible management of Ontario’s water, land and natural habitats through programs that balance human, environmental and economic needs.
