Regional Municipality of York; Pickering in the Regional Municipality of Durham; and Toronto. located near the
estuary Tributaries of the Rouge River also extend into the municipalities of

The total area of the watershed is , of which 40% is agricultural land, 35% urban, 24% forest/wetland/meadow and 1% watercourses/waterbodies. The headwaters of the Rouge River and its tributaries are found in the Oak Ridges Moraine. Water flows down from the elevated moraine to Lake Ontario. of the Rouge River The Rouge River meets Lake Ontario at Rouge Beach. At Rouge Beach, the Rouge Marsh is to the north and Lake Ontario to the south. More than half the remaining wetlands in the Greater Toronto Area are located here in the southern Rouge River. It is one of a few
wilderness areas left in South-Central Ontario and has been virtually untouched by development since the arrival of Europeans. While many exclusive homes and conclaves border this area on the southern tip, it is currently surrounded largely by agricultural land. It is even devoid of recreational development but sports a considerable network of walking or bicycle paths. Unlike other rivers in the Toronto area, it is allowed to fill its entire
flood plain on a regular basis rather than being forced through an artificial channel. However, parts of its watershed include the
Toronto Zoo and the Beare Road Landfill.
