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.

May 2021    

Due to current national lockdown restrictions as a result of the pandemic it has not been possible to hold any of our normal events during the first three months of 2021. Work parties, Wildfowl walks etc. which would have taken place in the period January to March have all had to be cancelled.

Herons breed early in the year and their 2021 nesting efforts are already well underway at the lake. A great video clip was recently captured by one of our offshore cameras. It shows a nest with three eggs plus an adult bird doing some site maintenance.

As usual, a dedicated team surveyed our butterflies in 2020. Butterfly numbers tend to peak in April and July but Covid-19 restrictions meant that the April peak was entirely missed this year. Nevertheless counts were conducted thereafter and these suggest that overall 2020 was a slightly below average year for butterflies.
