This is Loch Sloy, a magnificent example of Scottish civil engineering, built to capture rain for our domestic water supply. It is also a stunning feat of Irish workmanship. Donegal labourers came to this country around 1943 to replace the Scottish teenagers who had been shipped off in the war. They worked in the farms along Loch Lomondside, the Gareloch, Argyll and South Perthshire. These fantastic pictures were taken by Democrat reader Jimmy Johnstone. They reveal the hills and reservoirs which supply our water here in West Dunbartonshire.
