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.

2014 AGM Date

Unfortunately our 2014 events calendar, which we posted to all members along with a newsletter in early January, contained the wrong date for our 2014 AGM. Please note that the correct date is March 26th. For more details see our Annual General Meeting page.

Butterfly Survey 2013

In the late 1990s, butterflies were surveyed annually at Stocker’s Lake but a lack of volunteers resulted in the survey falling by the wayside for many years. However, in 2012, we revived the butterfly survey and now have an enthusiastic and increasingly knowledgeable team who walk the reserve recording butterfly life from April to September.


Land Appeal Target Reached

Wonderful Result! The appeal for the acquisition of our piece of river bank - see the news items dated May and October 2013 - has gone very well and we have now raised the £6,200 we required for the land and the conveyance. Many thanks to over 100 members who supported this appeal.

Volunteers Needed!

The work of FoSL requires volunteers. We have no paid professionals, though we employ contractors from time to time. Our committee members are all volunteers. So too are those who help on work parties, lead wildlife walks, conduct wildlife surveys etc.

We need more volunteers. Specifically we currently need to fill the positions listed below. Further information on each can be found by clicking on the job title concerned. For further information still, or to indicate interest, please call our Chairman, Ian Watson on 01923 282136.
