sentences:  In order to relieve flooding in the valley of the River Hull, water from the north of Foston, which formerly drained into the Hull, was diverted to a sea outfall at Barmston.In order to ensure that the water flowed in the opposite direction to the new outfall, various channels were made deeper, and a barrier was constructed at Foston, to prevent the water following its former course.Old Howe Lane, the road that runs from Foston to Beeford crosses the barrier, which is still labelled "The Barrier" on modern maps.
