this has not, as of 2020, progressed. Industry The river supplied water for multiple industries, including brewing and distilling, as well as skinners, tanners and dyers, and powered multiple mills. At least one mill seems may have pre-dated the Anglo-Norman invasion, as it is referenced in an early assignment of lands by King John. By around 1300, there already appear to already have been at least six mills: a pair of King's Mills and a pair named after a Doubleday, all between the castle and the Liffey, along with the Pool (later Pole) Mill by Dublin Castle, and the Schyeclappe Mill (for a long time the property of the Guild of Tailors) in what would become the Liberties. Later mills existed on all of the Dodder-Poddle City Watercourse, the Poddle proper, the inner City Watercourse, and possibly on other city-centre branch lines. On Mallet's list of mills, 12 are described as being within the Poddle system, while William Smith's list of 1879 has 40. Mills and industrial facilities supported by the City Watercourses and Poddle included: (on the first run of City Watercourse) the Bella Vista mill (Delaford paper mills), for a time Ireland's largest paper mill by volume and a flour mill at Templeogue and Mount Down Mill, which was a tuck mill, woollen mill, flour mill and eventually sawmill and hydroelectric generation point, (on the Poddle proper as far as The Tongue) a cutler's mill (water also being abstracted for Terenure House and its estate), two flour mills in Kimmage, one with its own millpond, and another flour mill in Crumlin (where the Sundrive Road shopping centre now stands), (on the inner City Watercourse) two iron mills, one of which later milled flour, (on the Poddle proper in Harold's Cross) a paper and wire mill later converted for flour production, a flour mill opposite Mount Jerome cemetery, a large cotton mill complex at Greenmount (employing 600 at its closure), and a "skin mill" (possibly for cleaning rabbit skins), (within the canals) the Marrowbone Lane Distillery on the Tenter Water channel, an iron foundry, a calico print works, and, at the rejoining of the Tenter Water with the Poddle, Busby's Flour (and also Oat and Oil) Mill (at Warrenmount), (in and near the Liberties) at least six tanneries, a glue factory, a wood-turning factory, a Jameson distillery, Caffrey's Brewery and two others, a bacon factory and at least three
