The Wash

The Wash is a rectangular bay and multiple estuary at the north-west corner of East Anglia on the East coast of England, where Norfolk meets Lincolnshire and both border the North Sea. One of Britain's broadest estuaries, it is fed by the rivers Witham, Welland, Nene and Great Ouse. It is a 620 km² (240 sq. mi.) biological Site of Special Scientific Interest. It is also a Nature Conservation Review site, Grade I, a National Nature Reserve, a Ramsar site, a Special Area of Conservation and a Special Protection Area. It is in the Norfolk Coast Area of Outstanding Natural Beauty and part of it is the Snettisham Royal Society for the Protection of Birds nature reserve. Geography The Wash makes a large indentation in the coastline of Eastern England that separates the curved coast of East Anglia from Lincolnshire. It is a large bay with three roughly straight sides meeting at right angles, each about in length. The eastern coast of the Wash is entirely within Norfolk, and extends from a point a little north of Hunstanton in the north to the mouth of the River Great Ouse at King's Lynn in the south. The opposing coast, which is roughly parallel to the east coast, runs from Gibraltar Point to the mouth of the River Welland, all within Lincolnshire. The southern coast runs roughly north-west to south-east, connecting these two river mouths and is punctuated by the mouth of a third river, the River Nene. Inland from the Wash the land is flat, low-lying and often marshy: these are the Fens of Lincolnshire, Cambridgeshire and Norfolk. To the east is the North Sea.
