Gaddings Dam is a locally owned reservoir near to Todmorden in West Yorkshire, England.

It is notable for having a sandy beach at the north-eastern side which attracts people to it during the summer months, although it is known for its all-year round wild swimming opportunities.

Historically, Gaddings Dam was actually two reservoirs built adjacent to each other, with water entering the valley via Lumbutts Clough.

[9] On hot days, people from the local area are known to make the 780-foot (240 m) hike to the dam to cool off (there is no direct road access).

[17] The owners state that the beach has been created by sandstone (the dominant local stone in the area) being broken down by weathering, and being pushed with the prevailing wind to the north-eastern edge of the reservoir.
