Loch Katrine is now owned by Scottish Water, and has been the primary water reservoir for much of the city of Glasgow and its surrounding areas since 1859.
BEAUTIFUL Loch Katrine in all thy majesty so grand,
Oh! how charming and fascinating is thy silver strand!
Thou certainly art most lovely, and worthy to be seen,
Especially thy beautiful bay and shrubberies green.
Then away to Loch Katrine in the summer time,
And feast on its scenery most lovely and sublime;
There’s no other scene can surpass in fair Scotland,
It’s surrounded by mountains and trees most grand.
And as I gaze upon it, let me pause and think,
How many people in Glasgow of its water drink,
That’s conveyed to them in pipes from its placid lake,
And are glad to get its water their thirst to slake.
From “Loch Katerine” by William McGonagall
