[2] Portions of the drainage basin extend into other municipalities of Leeds and Grenville, such as Athens, Elizabethtown-Kitley and Merrickville–Wolford.

The North Branch begins at Cranberry Lake in Merrickville–Wolford, and flows northeast, passes into North Grenville as it flows through the community of Bishop's Mills, before joining the main branch northeast of the community.

Combined, the creek continues north through the community of Oxford Mills, where it goes over Oxford Mills Dam, flows under the Canadian Pacific Railway main line, heads through Kemptville, where it takes in the right tributary Barnes Creek, and reaches its mouth at the Rideau River.

The creek is navigable, for smaller watercraft, from the Rideau River to the town docks in Kemptville.

In the spring, it should be possible to canoe from Oxford Station Road (or further) to the Rideau River with one portage.
