Arnfield Reservoir Claimed

Arnfield Reservoir is a man-made lake in Longdendale in a valley near Glossop.

It was constructed in 1854 as part of the Longdendale chain to supply water from the River Etherow to the urban areas of Greater Manchester.

Unlike the other reservoirs in the chain, Arnfield and Hollingworth Reservoir are not in the Etherow valley but lie in the valley of tributary brooks to the north and above (Arnfield lies around 1 mile from Bottoms Reservoir in the Longdendale Chain).

From Arnfield the water is extracted to pass through the Mottram Tunnel to Godley.

In 1990 the Hollingworth Reservoir (now part of Swallows Wood nature reserve) was decommissioned and levelled and waters from the Ogden Brook fed into Arnfield.
