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.

Work starts on new land

Work has started on the ‘Margaret Partridge Plot’!

On Sunday 12th April 2015 we broke new ground by working on the new strip of land which we acquired, thanks to members’ generosity, in 2013.

For further information see the report on our Work Party Reports page

Ricky Museum

FoSL have been fortunate enough to be given an opportunity to set up a display in Rickmansworth Museum in March. The plan is to create a display that reflects the diversity of wildlife in and around Stockers Lake Nature Reserve. By informing residents about the work FoSL does to preserve this valuable local Reserve, we hope that the exhibit will attract new members who will actively support our Association. Any ideas?  Phone Sue Sanderson - 01923 445541

Updated Butterfly and Dragonfly walk report

A brief report by Barbara James of our August 2014 butterfly and dragonfly walk was provided in the October 2014 FoSL newsletter. However a more detailed, illustrated version written by walk leaders Jane Archer (Dragonflies) and Cliff Buckton (Butterflies) is now on our event reports page or available from here.

Butterfly Survey 2014

As in previous years, a small but dedicated band of enthusiasts have recorded butterfly sightings during the summer of 2014. Each week, a recorder walked around the Lake recording all butterflies seen. Thanks to our excellent team of butterfly recorders, Carol and Dick Beeden, Cliff and Jacky Buckton, Carrol Scott, and leader Barbara James, we have some interesting results. For full details please download our 2014 butterfly survey report from here. Alternatively, read on for a brief synopsis of the main findings.
