The Chater is about 12 miles long. It rises near Whatborough Hill in Leicestershire, and then flows east, past the sites of Sauvey Castle, and Launde Abbey, before crossing the county boundary with Rutland.
In Rutland the river continues east, to the north of Ridlington, Preston, and then to the south of Manton and the north of Wing. At North Luffenham, it meets a stream that had risen south of Ridlington. It continues northeast, going through Ketton, before meeting the River Welland.
The river holds a variety of fish species, including roach, dace and chub.
