Stocker’s Lake was formed by gravel extraction. Now a wide range of aquatic plants have become established. It was designated as a Local Nature Reserve in 1984 and is managed by Herts & Middlesex Wildlife Trust. The lake is characterised by gravel ridges which form a series of islands providing an important refuge for wildlife. Ducks are abundant in winter. Shoveler and Goldeneye visit in nationally important numbers, and Smew and Pochard are occasional. In the breeding season, Common Tern nest on floating rafts and there are good views of the large heronry.
