 The Chase is crossed by the River Torne, for which a new channel was cut by Vermuyden in 1628, as part of the drainage scheme implemented at that time.Further north, the two peat bogs were separated by the completion in 1802 of the Stainforth and Keadby Canal, running in an east-west direction between the two.In the 1970s, the Chase was further divided by the construction of the M180 motorway, which runs to the south of the canal but follows a similar course.
