The creek is named for the distance from the river's mouth to the western end of Lake Ontario.[3] It was previously known to the Mississauga Indians in their language as Ne-sauga y-onk or niizhozaagiwan ("having two outlets")[4] and to the French as Rivière de Gravois ("gravelly river").[5]

Like many creeks draining into Lake Ontario, Sixteen Mile Creek has cut a deep valley that is home to a broad range of wildlife, including whitetail deer, raccoons, foxes, opossum, and squirrels.[6] The forest contains tree species typical of the Carolinian forest habitat,[7] although since this is close to the northern limit of this zone, some are poorly represented. The total area of the drainage basin is 372 square kilometres (144 sq mi).[8]

In Oakville, it also forms part of Glen Abbey Golf Course[9] and is home to the Oakville Yacht Squadron.[10]
