The excellent island in the Wash, well worth a visit.

Our competition to find the purpose of the Island are now closed. The winning entry came from the 1976 report on the feasibility study of The Wash Water Storage Scheme. This suggested the bank was used as an inshore trial bank. The bank was built in 1972. It measures 60m in length and is 12m high with side slopes of 1 in 4 gradient. The construction of this island led to a second larger island being built 4.5 miles out to sea. That island contains a lake of one hectare. The full Wash Water Storage Scheme proposed to create large fresh water reservoirs by banking off large sections of the Wash between the outfalls of the Nene and the Great Ouse. The conclusions of the feasibility study were largely that although such a scheme was technically achievable, there wasn't generally such a demand for water as to warrant the large costs involved. However the report didn't rule out such a scheme becoming necessary sometime in the future.
