Stocker's Lake

Stocker's Lake is an old flooded gravel pit of approx 90 acres (37.5ha) at Rickmansworth, Hertfordshire, England, within the Colne Valley Regional Park[1] which is designated as a Local Nature Reserve.

[5] The lake has a number of small islands and is surrounded by mixed woodland, alder carr and willow scrub.

Situated on the North-South Flyway of the Colne Valley, the reserve is especially attractive to birds both in spring, when many migratory passerines pass through, and in winter, when the lake is full of waterfowl.

Common terns nest on specially constructed rafts moored on the lake, and the heronry is the largest in Hertfordshire.

Entrance to the reserve is via Rickmansworth Aquadrome, where there is car parking.
