The man-made loch at Stobo serves as a feeder to the Japanese Water Garden at the farthest end where it drops via a sleuth gate system to a pond below as a waterfall. This then feeds the streams through the garden. For those who have not been there it is an amazing treasure here in the Scottish Borders and is the private property of Stobo Home Farm, not Stobo Castle. Stobo, Tweed Valley, Scottish Borders
