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

From this point it flows south-east through the V-shaped valley known as Ashes Hollow, to reach the village of Little Stretton.

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.

[2][1] The principal tributary of the Quinny is the Byne Brook, which flows through Ape Dale at the foot of Wenlock Edge.

This is the middle band in the five part framework scale, which ranges from high, good, and moderate, through to poor and finally bad.
