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.

On Saturday 7th December local members of the Jain gathered with FoSL representatives to plant an English Oak tree to commemorate the 150th birth anniversary of Mahatma Gandhi.

At the Rural Living Awards evening on October 18th at County Hall, Hertford, Three Rivers groups did very well with Friends of Stocker’s Lake winning the top and prestigious Chairman’s Award.

2019 was a good year for butterflies around the lake with a total of 826 butterflies counted through the summer. This is the second highest count since the current surveys started in 2012, and is comparable to that of 2017. The count was 26% down on 2018 but due to weather conditions 2018 was an exceptional year. 

Following a chance meeting Martin Ketcher of Herts & Middx Wildlife Trust (HMWT) asked FoSL to help encourage the return of the delightful water vole to the River Colne that borders one side of our reserve. The water vole is of course “Ratty” in the “Wind in the Willows”. Water voles were seen on our reserve in the 1990s but when mink arrived they disappeared.

Good News! After 6 years of effort and planning, cattle will be introduced to our meadows between the River Colne and the Lake from the new enclosure near the iron bridge at 10 am, on Saturday 8th June.
