Modern reservoir. Date from www.yorkshirewater.com (2004). Previously early enclosure with small strips of woodland along the river some of this woodland surviving along northern edge of present reservoir. Northern and Eastern former valley sides occupied by enclosed strip systems on 1851 mapping. Royd Moor side likely to have been moorland. The earliest map evidence of a small reservoir (HSY5984) adjacent to this polygon marked on the 1893 map (Barnsley Corporation Water Works). Legibility of the enclosures is invisible as fully covered by the reservoir.
