Worth a visit

Loch Thom was constructed by 1827 and was increased and expanded in 1872 to its modern-day capacity of 11365 million litres of water.
It was once owned by the Shaw Water Company but is now operated by Scottish Water. A direct pipe was installed to the Whinhill water treatment plant in 1971 rendering the Greenock Cut aqueduct obsolete. Loch Thom continues to provide drinking water for Greenock 200 years later!

Wildlife: Water fowl and gulls are a common sight with greater black gull nesting annually on the small island on the eastern side of the loch.
