Officially designated as a river,[1] the Rouchel Brook rises below Big Losy Mountain on the western slopes of the Mount Royal Range. The river flows generally south of west, joined by two minor tributaries, before reaching its confluence with the Hunter River south of Glenbawn Dam, east of Aberdeen. Rouchel Brook descends 652 metres (2,139 ft) over its 46 kilometres (29 mi) course.[2]
