Junction Creek (also known as Nibi Nikwjiwong) is the central urban stream of Greater Sudbury/ N’Swakamok and is part of the Lake Huron watershed. The creek stretches 52 km from Garson through a Provincially Significant Wetland, under the downtown core, and connects to the Vermilion River and Spanish River before it drains into the North Channel and Lake Huron. Numerous communities are connected to Junction Creek and impacted by its condition.
The Junction Creek watershed is a natural valued asset. It serves as a wildlife corridor and accessible green space in an urban centre where past development has compromised its health. The watershed plays an important role in flood management, carbon storage, offers recreational and research opportunities, has historical and cultural significance, and supports diverse natural heritage. Restoring the watershed to a thriving ecosystem results in mutual benefits towards the health and resilience of the community and economic growth.
