It rises near Whatborough Hill in
Leicestershire, and then flows east, past
Sauvey Castle and
Launde Abbey, before crossing into
Rutland.
Chater Valley is a biological
Site of Special Scientific Interest north of
Loddington, Leicestershire. The river continues east, to the north of
Ridlington,
Preston, and then to the south of
Manton and the north of
Wing. North-east of
South Luffenham, it is joined by the
Morcott Brook. It continues north-east, going under the
A6121 road at Foster's Bridge and through
Ketton, before meeting the River Welland near
Tinwell. The river drains an area of that is mostly clay, but with limestone and sandstone in certain areas. The catchment is rural, with mixed farming and woodland in its lower reaches. Originally, the project for the massive reservoir of
Rutland Water considered damming the valley of the Chater, but the underlying geology was not conducive for this. Additionally, the available land space would have made the reservoir smaller than the eventual site of Rutland Water. ==Wildlife==
