The South Forty Foot Drain aka Black Sluice is a man-made drain starting at Guthram Gowt [Map] that drains a large area of the Lincolnshire fen-land known as the Black Sluice Area aka Lindsey Level. The drain, or an early version of it was first constructed around 1635 when the Earl of Lindsey agreed with the Commissioners of Sewers for Lincolnshire to carry out drainage works which would make 150 km² of land available for agricultural use. The South Forty Foot Drain drains the area bounded by Great Hale, North Kesteven [Map], Bourne, South Kesteven [Map], Pinchbeck [Map] and Boston [Map].
