Gaddings Dam is an 1833 earth embankment dam located on top of the moors between Todmorden and Walsden. Constructed to supply water to the mills of Lumbutts, the reservoir fell into disuse when the mills began to use steam power.
Slated to be drained in 2001 due to its poor condition, the reservoir was rescued by a determined group of locals who bought the dam, repaired it, and now continue to maintain it to the standards required by the regulations.
There is no road access to Gaddings Dam, it can only be reached by a steep hike on a rough footpath to the top of the moors. The nearest vehicle access point is the Shepherd's Rest pub on Lumbutts road. Parking is very limited, there is room for only about a dozen cars.
