The Allt Graad (Scottish Gaelic: Allt Grànnda: Ugly Stream) or River Glass is a river in Easter Ross, Highland, Scotland. It is named on Ordnance Survey maps variously as Allt Graad and River Glass.[1] It has also been known as the "Allt Grande", and the archaic Anglicization, "Aultgraad".
As of 2011, a hydro-electric scheme is under construction on the Allt Graad. This run-of-the-river scheme is on the lower catchment of the river, next to the Black Rock Gorge. It will be operated by RWE Npower, and have a capacity of 3.5MW.[2]
