Mercers Lake

Mercers Lake is a body of water in Mercers Park, Merstham, near Redhill, Surrey. It is a former quarry that has been adapted for water sports, such as sailing, kayaking, and paddle boarding.

History

The lake was originally a sand quarry created by British Industrial Sands.
The water sports centre was expanded to a larger cafe and adventure playground in early 2025.

Activities

The lake is used for fishing and contains perch, bream, pike, and large carp.
The lake is also used for scuba diving courses by Oyster Diving, a PADI Dive Centre. There are facilities for setting up equipment, hiring equipment and having guided dives. The lake is up to 15 m deep, and contains the remains of the front of a Cessna plane, other sunken attractions and an underwater forest.

Accidents and incidents

A 31-year-old man named Edward Savage drowned in the lake in June 2018. Local police had received a number of calls about youths swimming in the lake earlier in the week. The death was not connected to the company who run water sports there.
In 2023 a swan was killed with a brick, following a similar incident in 2022, where a swan was shot with a ball bearing.
