It is 4 miles (6 km) long and is a tributary of the Sevenmile River.
The river begins as a series of small streams and swamps in North Attleboro, between Emerald Mall to the east and the Cumberland, Rhode Island border to the west.
From there it flows south, picks up flow from Benjamin's Brook and crosses the border into Attleboro.
There it receives Como Brook before reaching the Sevenmile River just north of the Rhode Island border.
