The Ouse Washes form a vital component of the flood defences of the Cambridgeshire fens, providing flood storage and conveyance when the normal channels are at full capacity. The flood defence and environmental value of the Ouse Washes depends upon the maintenance of an open grassland which is regularly flooded in winter, but dry enough in summer. A strategic study of the system was completed in 1995, which recommended that (a) summer flooding should be better controlled and (b) the structures contained within the Washes were improved. This paper considers some of the economic and environmental problems which were encountered during the development of the strategy and examines operational aspects of the design.
