The Wash is the square-mouthed bay and estuary at the north-west corner of East Anglia on the East coast of England, where Norfolk meets Lincolnshire. It is among the largest estuaries in the United Kingdom. The Wash is fed by the rivers Witham, Welland, Nene and Great Ouse. The coastline runs from near Hunstanton to Gibraltar Point.
Owing to deposits of sediment and land reclamation, the coastline of the Wash has altered markedly within historical times; several towns once on the coast of the Wash (notably King's Lynn) are now some distance inland. Much of the Wash itself is very shallow, with several large sandbanks, such as Breast Sand, Bulldog Sand, Roger Sand and Old South Sand, which are exposed at low tide, especially along the south coast. For this reason, navigation in the Wash can be hazardous.
