I've finally finished the big Flowerbed at the Entrance of my Chinese Garden. Now I want to build the new Enclosure for my Formosan Black Bears and I want it to be a circular Island. Is there a Way to dig a Moat directly next to the Path and with a smooth Edge? I know I could delete the Path, dig the Moat and replace the Path as a raised Path but as far as I know I wouldn't be able to fill it with Water if I would do it that Way
