The reservoir of Dean Mills is situated high on the southwestern extension of Winter Hill known as Counting Hill and above the Smithills area of Bolton. This was once a pair of small reservoirs that served Dean Mills down in the valley below at Barrow Bridge. Known locally in the 20th Century as The Pan-handle.
One reservoir remains, the other was drained long ago and although completely overgrown with moorland vegetation, the outline of its embankments can still be seen in a roughly triangular shape.
