Lake Simcoe is a moderately sized lake located approximately 60-km north of the City of Toronto, Lake Simcoe is a little more than an hour's drive from half the population in Ontario. The watershed has a total land and water surface area of 3,580 km2, of which the lake occupies about 20 percent or 722 km2. Lake Simcoe is part of the Trent Severn Waterway connecting Lake Ontario to Georgian Bay and is southern Ontario's largest body of water excluding the Great Lakes.
The land portion of the watershed is approximately 2,858 km2 and is drained by 35 tributary rivers, with five major tributaries accounting for over 60 percent of the total area. Most of these rivers originate along the southern boundary of the watershed in the prominent physiographic feature known as the Oak Ridges Moraine. These rivers then drain in a northerly direction before discharging to Lake Simcoe.
Lake Simcoe acts as the boundary between the two travel areas of the Georgian Lakelands in the west and Getaway Country in the east. There are a number of communities bordering Lake Simcoe within the County of Simcoe, the Regional Municipality of York, and the Regional Municipality of Durham.
