Yep. Stormwater drainage pipes take water from the house out to the gutter, where it runs down to the drain & eventually to a creek / lake / sea. Canals are big things that can take boats, not little gutters for water. If you're feeding water to a field, it's runs via an irrigation "channel". Aren't mills usually fed from *"The Old Mill Stream"* :-) & most fountains I know are either in the middle of a lake / pond, or fed by underground pipes. So should we add gutter & channel to the list of features? Thanks Graeme
