Ok, a bit more geography then:
Noran Water
A river of Angus that rises in headstreams in the southern Grampians, the Noran Water flows southwards to the valley of Strathmore through Glen Ogil in the Braes of Angus, forming a reservoir in the glen and a cascade at the Falls of Drumly Harry. It turns southeast at the Den of Ogil and flows on to meet River South Esk west of Brechin.
