Blantyre is bounded by various watercourses: two of them unattractively named -- the Rotten Calder and the Rotten Burn. I have no explanation for the "Rotten" name -- per Wiki, the little Rotten Calder river looks quite rural, through pretty scenes, and is in fact, at least clean enough to have fish in it ! Far to the south, there is another watercourse which is seemingly more pleasant than its name might suggest: in the Norfolk Broads area, the Muck Fleet -- a very shallow and totally un-navigable tributary of the River Bure, draining several "lesser" broads. Chief settlement of this "patch" of the region, is Fleggburgh -- aka (same village, different names) Burgh St. Margaret, Norfolk.
