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.

New Gallery Pictures

16 year old Matt Livesey this month submitted some superb pictures which he took recently at Springwell and Stocker's Lakes. e.g. the one shown of a Little Egret. Visit our gallery page to see these and some other pictures taken on or around the reserve over the years by our members or friends. If you have any pictures of your own that you would like to contribute to our gallery section, please send them to This email address is being protected from spambots.

New Walks Confirmed

We are now able to confirm two guided walks around the reserve this summer. Our 2014 events calendar gave a different date for our usual annual wildflower walk and the butterfly/dragonfly walk wasn't listed there at all. This is because at the start of the year neither walk had a leader assigned. However leaders for both have now been found for June 22nd and August 17th respectively. So both are now firmly scheduled. For full details see our events listing.

Breeding Goldeneye

A family party of Goldeneye has been spotted several times over the last few days at SPRINGWELL LAKE (adjacent to Stocker's Lake). Goldeneye primarily breed on Scottish lochs and there have only ever been a handful of UK records of Goldeneye breeding away from Northern England and Scotland. 


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.
