The Fritchley Sough discharges into a stream below Mill Green. Approx. 250m further north (upstream) there are two adjacent soughs, well constructed with stone walls and a stone roof. They are east of an old tip and south of a small field by an engine shed at a tramway junction. One sough (dry) trends to the north east and possible links to the dry brook south of the old Warner's Quarry. The other sough, with a good flow of water curves round to the north west. Both appear to be accessible. Does anyone know the history of these soughs, route and purpose? I suspect they are associated with quarry drainage!
