The Watershed

At 44 km long, the Carp River is the only river that flows entirely within the boundaries of the City of Ottawa.

Carp River headwaters flowing from under Eagleson Road south into Ravine Park in Glen Cairn.

The Carp River is a navigable waterway that comes under the jurisdiction of the Federal  Fisheries Act.  The river’s watershed drains an area of roughly 306km2 spread across Stittsville, Kanata, and West Carleton.  The headwaters originate near the Stony Swamp Wetland Complex on  NCC land (Old Quarry Trail, P5) at Eagleson Road near Hazeldean Road in Kanata.  The upper Carp River (also called Carp Creek) runs southwest from Appaloosa Park under Eagleson Road through Glen Cairn where it empties into the marshes and storm water ponds south of  the Canadian Tire Centre.  From here it flows north for about 42 km through West Carleton into the Ottawa River at Fitzroy Harbour. 

Major tributaries of the Carp River include:  Poole Creek, Feedmill Creek, Huntley Creek, and Corkery Creek.
