In the heart of The Fens, the Ouse Washes forms the largest area of washland (grazing pasture that floods in the winter) in the UK. The reserve attracts thousands of ducks and swans in winter, and in spring, hundreds of snipe, lapwings and redshanks breed. This is an excellent site for dragonflies in summer. Shallow flood levels provide the best viewing conditions for winter ducks and swans. You can call the reserve for an update on the current flood level.
