Most of what was once a five hectare (13 acre) lake, formed by the damming of Siston Brook, is now a mobile home park. The lake would have been an important feature of William Champion’s brass and copper works, providing water to run a series of water wheels.
It also, of course, provided a most pleasing aspect of the gardens, and Champion’s guests would no doubt have marvelled at the 9 metre (30 foot) high statue of Neptune which held court over the waters. Later occupants of Warmley House held skating parties in the winter.
