It is named after the pioneer settlement German Mills, founded by William Berczy in 1796. The settlement disappeared after a few years, but the creek retained the name. The Richmond Hill portions of the river snake through residential development with a very narrow greenbelt on either side of the creek. The Markham sections run through a mix of residential, commercial and light industrial areas.
Duncan Woods Creek is a small left tributary that flows northwest to German Mills Creek in Toronto, at the southeast corner of Steeles Avenue and Leslie Street.[2]
There are a few undeveloped portions along the creek, mostly as parks in Markham.
