Luggate Water, a rivulet of Stow parish, Edinburgh. Formed by two small head-streams, which rise close to the Peeblesshire border, it runs 4¾ miles south-eastward to Gala Water, at a point 1 mile SSW of Stow village. It is a cold hill stream, fed by many rills, subject to sudden freshets, and containing great store of trout. Two old castles stood on its banks, on spots hr. and 1¾ mile from its influx to Gala Water; and both of them have left some remains.—Ord. Sur., sh. 25, 1865.
