One of its sourcess rises at Postling near Hythe and becomes the River East Stour. Another rises at Lenham near Maidstone and becomes the River West Stour. They join at Ashford to become the River Great Stour.
The Great Stour flows through Canterbury and Plucks Gutter. The River Little Stour then joins the Great Stour to become the River Stour. The River Wantsum joins here, too, and the Stour flows through Sandwich and into the English Channel at Ramsgate.
