Kirk Dam
Argyll and Bute, United Kingdom
Kirk Dam is an impounding dam, located 1.5 kilometres south of Rothesay, and is separated by a causeway from the much larger Loch Fad to the south-west. It was built to provide water to the cotton mills of the town, and is now the habitat for a variety of marshland birds. The earthfill dam is 6 metres high and records show it was constructed in the late 18th century.
