Ouse Washes The Ouse Washes are a low-lying floodplain in the Fens of eastern England where the River Great Ouse flows between sluices and washes, creating a seasonally inundated landscape noted for its importance to waterfowl and wetland biodiversity. The area forms part of multiple statutory designations including Site of Special Scientific Interest, Special Protection Area and Ramsar listing, and lies within the historic counties of Cambridgeshire and Norfolk. Its management involves partnerships among agencies such as Natural England, the Environment Agency, and non-governmental organisations including the Royal Society for the Protection of Birds and the Wildfowl & Wetlands Trust.
Geography and Hydrology
The washes are a managed floodplain created by embanking the River Great Ouse between sluices at Earith and Downham Market, lying adjacent to the Fenland and bounded by towns and parishes including March, Wisbech, Littleport, and Downham Market. Hydrologically the system relies on gravity drainage, sluice operation, and washland inundation to attenuate flood peaks originating in the Huntingdonshire and Bedfordshire catchments, and connects to the The Wash via tidal influence downstream at King's Lynn. Key engineered structures include the Old Bedford River and the New Bedford River, historic arterial channels constructed during the Drainage of the Fens schemes and influenced by figures such as Cornelius Vermuyden. Seasonal flooding creates a mosaic of open water, shallow pools, and flood meadow that is integral to the area's role in the Anglian watercourse network.
History and Land Use
The landscape reflects successive interventions from medieval fen commons through the 17th-century drainage projects led by Cornelius Vermuyden to 19th- and 20th-century agricultural intensification associated with Britannia Works and local drainage boards. Enclosure acts and land reclamation by the Adventurers altered common rights, while later hydraulic engineering by entities such as the Earith Sluice authorities and the Middle Level Commissioners refined water control. During the 20th century, wartime infrastructure and post-war agricultural policy including the Agricultural Act 1947 promoted arable production on adjacent soils, while flood events—most notably the 1947 floods—reinforced the washes’ role as emergency storage. Recent policy drivers from the European Union—including Birds Directive and Habitat Directive instruments—have shaped land-use agreements and agri-environment schemes administered by bodies like the Rural Payments Agency.
Ecology and Wildlife
The site supports internationally important populations of wintering wildfowl and waders such as Whooper Swan, Bewick's Swan, Wigeon, Teal, Shoveler, Tundra Bean Goose, Lapwing, and Black-tailed Godwit. Habitats include species-rich flood meadow grazed by traditional cattle and sheep, reedbeds supporting Reed Warbler and Bittern, and open waterused by diving species including Pochard and Great Crested Grebe. The washes provide breeding and staging habitat for migratory species following routes tied to the East Atlantic Flyway and links with sites such as RSPB Minsmere, Humber Estuary, and Lindisfarne National Nature Reserve. Vegetation communities reflect fen peat and alluvial soils with notable plants including Common Reed, reedbed specialists, and wet grassland flora typical of Lowland Meadow designations; invertebrate assemblages include aquatic beetles and dragonflies associated with standing water.
Conservation and Management
Conservation is delivered through a framework of statutory protection—Site of Special Scientific Interest notification, Special Area of Conservation considerations where applicable, and Ramsar criteria—combined with local management by organisations such as Natural England, the Royal Society for the Protection of Birds, and the Wildfowl & Wetlands Trust. Management tools include water-level manipulation using sluices and pumps, rotational grazing regimes common to traditional grazing, and seasonal mowing under agri-environment schemes like Higher Level Stewardship and its successors. Monitoring programmes coordinate with national surveys such as the Wetland Bird Survey and the Breeding Bird Survey to track population trends for species listed under the Birds Directive and UK Biodiversity Action Plan. Challenges include invasive species control, peat subsidence linked to peatland drainage, and balancing flood risk management with biodiversity outcomes—a nexus involving the Environment Agency and regional flood defence strategies.
Recreation and Access
Public access is concentrated around nature reserves and hides managed by the RSPB and Wildfowl & Wetlands Trust, with viewpoints near settlements including Earith, March and Downham Market. Recreational activities include birdwatching linked to national groups such as the British Trust for Ornithology, guided walks, and seasonal events promoted by local organisations like parish councils and the Fenland District Council. Access is regulated to protect sensitive wintering and breeding areas, with public rights of way connecting to long-distance routes such as the Fen Rivers Way and proximate cycle networks associated with National Cycle Route 1. Visitor information and interpretation are provided at nearby visitor centres and museums including the Wisbech & Fenland Museum and regional outreach by conservation charities.
