The Waulkmill Glen reservoir was built in 1847 followed closely by the Ryat Linn reservoir one year later . They were built to supply the Gorbals in Glasgow with clean water by the GGWC (Gorbals Gravitation Water Company)

The structure in the reservoir is a draw-off tower which controls the water flow and these allow the reservoir to be drained if necessary

The reservoirs are now part of the Dams to Darnley Country Park which is very popular with anglers , cyclists and walkers
