Watershed and Navigation
A number of southern Ontario rivers flow, generally north, into the lake, draining 2,581 km2 (997 sq mi) of land. From the east, the Talbot River, part of the Trent-Severn Waterway is the most important river draining into Lake Simcoe, connecting the lake with the Kawartha lakes system and Lake Ontario. From its connection to Lake Couchiching, the Severn River is the only drainage from the lake to Georgian Bay, part of Lake Huron (Simcoe itself is not one of the Great Lakes). The canal locks of the Trent-Severn Waterway make this connection navigable.
A number of creeks and rivers flow into the lake:
- Bluffs Creek
- Beaverton River (Beaver River)
- Holland River
- Maskinonge River
- Pefferlaw River
- Black River
- Talbot River
- White's Creek
