Drained land of 'Thorpe Marsh' . The drainage of this land probably dated to the Parliamentary Enclosure award of 1768 for 'Thorpe Marsh (Thorpe in Balne)' (Sheffield Archives Catalogue Ref. LD 1122). Original drained character of this land dramatically altered at the time of the construction of Thorpe Marsh Power Station in the 1960s and the canalisation of a section of the River Don across some of the earlier enclosures.
