Modern reservoir built between 1894 & 1906 O.S mapping, fed into by Snailsden reservoir and feeding into Winscar Reservoir. Predominantly unenclosed moorland shown on 1894 OS map, though there are a few fields to the north of the stream. Previous type invisible. The origin of the former moorland landscape is uncertain though this area is likely to be moorland by the Roman period (see Bevan 2003 for discussion of environmental evidence in region).
