Welcome to the Friends of Stocker's Lake Website

This website is owned and maintained by Friends of Stocker’s Lake (FoSL), a registered charity. FoSL exists to :

  1. - conserve, safeguard and enhance Stocker's Lake as a Local Nature Reserve
  2. - help and extend the scope of the work of the warden at Stocker's Lake
  3. - foster public support for and appreciation of Stocker's Lake as a local nature reserve.

Stocker's Lake, near Rickmansworth just inside the M25, is bordered on one side by the river Colne and on the other by the Grand Union canal. It is a place of great beauty and it supports a huge variety of wildlife, especially birds, particularly winter wildfowl. It is owned by Affinity Water and managed by Herts & Middlesex Wildlife Trust, actively supported by local people who are the Friends of Stocker’s Lake.

Within this website you will find details of organised walks and other events on the reserve, news of interesting recent sightings of birds, details of how to join FoSL for a mere £5 per year, and much more.

A recent evening of bat research at the lake has yielded some amazing results. A total of 55 bats were trapped in a single night, of which no fewer than eight turned out to be rare Nathusius Pipistrelle bats. These included one bearing a ring showing that he had travelled around 1,000 miles from Latvia!

We mentioned at this year's AGM that we plan to set up a camera to overlook the heronry on one of the islands in the lake. Recently we met with a company which has installed similar systems around the country, including in the Lee Valley and Dorset. See the full article for two images of the type we expect to be able to display next breeding season.

Did you know that FoSL has its own Facebook page? You can visit it here. Our treasurer, Dick Beeden visited Tichwell RSPB reserve in Norfolk over the weekend. Visit FoSL on facebook to see his video of a bittern.
