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.

Thank you to everyone who contributed to our recent website survey. We received 164 responses altogether; a terrific result which will provide invaluable input to the website upgrade and relaunch which we are now sstarting to plan. Results from both that survey and the associated review will be published on this site in due course.

Good news! The Dexter cows, so vital to our strategic aim of restoring wildflowers to several meadows on the reserve, returned for the summer season on Sunday May 30th. The accompanying image, taken on June 10th, shows them happily in place on  the reserve.

Please give a few minutes of your time to feedback what you think of this website by completing our survey at https://www.surveymonkey.co.uk/r/FoSL2021. This will provide us with important feedback as we prepare to upgrade the site from the autumn.

At its recent meeting on May 4th our Committee approved an updated version of FoSL's Privacy and Data Implementation policies. For more details please visit our Privacy Statement page.
