Scaling Dam Reservoir is a freshwater man-made lake on the edge of the A171 road in North Yorkshire, England.

[4] The area that the reservoir is built in was named Scaling Dam long before the reservoir was built in 1958; mapping and records show a hamlet of Scaling Dam in the early nineteenth century,[5][6] and the name is mentioned in Camden's 17th century "Britannia".

[12] As the Environment Agency classify the water quality as being good,[13] Scaling Dam Reservoir is a suitable venue for angling, walking and swimming.

[15] There is a visitor centre and shop which sells angling supplies and parts of the reservoir are accessible for disabled anglers.

[16] Besides the fish (which have been introduced for angling), the site is noted for a regular appearance of ospreys during the spring and summer months,[17] and the Nathusius' pipistrelle bat.
