Quinny Brook

Quinny Brook is a tributary stream of the River Onny which flows through the Shropshire Hills Area of Outstanding Natural Beauty in England.

Course

Its source is a spring called Boiling Well on the dissected plateau of the Long Mynd, adjacent to a number of round barrows. From this point it flows south-east through the V-shaped valley known as Ashes Hollow, to reach the village of Little Stretton.
After passing through Little Stretton, the watercourse heads south towards Marshbrook and Strefford. To the north of Strefford, it is joined by its main tributary the Byne Brook. The now larger brook is forded at Strefford from where it flows south-westerly to The Grove and Berrymill cottage, south of Wistanstow, where it joins the River Onny. The brook has a total length of.
The drainage basin for the brook, which lies between that of the River Onny to the west, the Cound Brook to the east, and that of the River Corve to the south, has an area of.

Byne brook

The principal tributary of the Quinny is the Byne Brook, which flows through Ape Dale at the foot of Wenlock Edge. Its source is near Rushbury, where it is known as Lakehouse brook, and it is also known as Eaton brook as it passes the village of Eaton-under-Heywood. The Byne brook is 14.3 km long and has a catchment area of, thereby contributing nearly two-thirds of the total catchment area of the Quinny brook.
