Sutton Mill Dam, Nature park and reservoir in Sutton district, St Helens, United Kingdom.
Sutton Mill Dam is a reservoir formed by damming Pendlebury Brook, located between Clock Face Road and Mill Lane in the St Helens area. The site contains water surrounded by grassy banks, tree lines, and open green space that attracts birds and small wildlife.
The reservoir was saved from industrial dumping in the 1970s when local residents organized to protect it from pollution. The site was officially designated as a wildlife park in 1987, marking its transformation into a protected natural space.
The site serves as a gathering place for local anglers who fish here regularly and share knowledge about the water and its wildlife. The community has developed a strong connection to the lake as a space for outdoor activity and nature watching.
You can enter the site from Mill Lane or Mill Brow, with parking available near the entrances. The best time to visit is during dry weather when the paths are easy to walk and the setting feels most welcoming.
At the outlet of the lake sits a distinctive stone waterfall with stepped levels where water cascades downward. This feature creates a direct connection between the lake and Sutton Brook, which flows onward into the St Helens Canal system.
