Currently it starts at the confluence of Borthwick and Ramsey Creeks just west of the Walkley Road off-ramp from Highway 417 and flows 13.4 kilometres (8+1⁄4 miles) to the Ottawa River.

It is likely that the area around Blackburn Hamlet was first used by humans around 10,500 years ago when bands from the late-paleo period began to hunt the forests that were beginning to take root after the end of glaciation and the retreat of the sea.

For most of the next 200 years trappers, traders and the famed coureur des bois travelled up and down the Ottawa River until the first European settlements in the area took root after 1800.

While Samuel De Champlain’s early exploration of the Ottawa River is generally well known, it was in fact his protégé, Étienne Brulé, who was the first European to pass by the mouth of Green’s Creek in 1610.

Later, an 1880 map of Gloucester Township showed a different sawmill located at the mouth of the creek on the land of William Mosgrove, and by some accounts that industry remained in operation until the early 1900s.

Initially a small ferry existed to carry passengers and freight across the creek, charging users between 10 and 20 cents on their way between Bytown and Orléans, Ontario.

The 1863 map of Carleton County shows a hotel owned by Joseph Lafleur near the location of the present-day Montreal Road interchange on Highway 174.

The spring, which was situated on the west bank of Green’s Creek just upstream from Montreal Road had a flow rate of 250 gallons per hour and contained particularly high levels of hydrogen sulphide and methane.

Nearby, Besserer’s Wharf acted as a port of call for the Ottawa River steamer “Empress” and families from the city would come out on weekends for a country getaway.

An advertisement in the Ottawa Journal from 1896 promised as a pleasant place for picnic parties where visitors could depend upon “good food at reasonable prices.” Green’s Creek is also well known for the small mineral concretions containing the remains of fresh and saltwater marine life that can be found along its shores.

Specimens up to 10,000 years old containing the remains of near complete fish skeletons, ancient whale and seal bones and numerous smaller marine and terrestrial fauna have all been found along the shores of Green’s Creek.

On the land, mammals such as beaver, muskrat, coyotes, chipmunks, racoons, skunks, foxes, deer and even the occasional moose can be found along its banks.
