 Water from the river eventually enters the sea at Spurn Head at the mouth of the Humber Estuary.During the drought of 1995/96 Yorkshire Water installed a pipeline connecting the River Tees near Darlington to the river near Birkby, south of Great Smeaton.This link enables water to be transferred from the Tyne and Wear into the Tees and then to the Wiske for pumping out from the River Ouse at York.
