Isaac River
Rising below Plum Duff ()southeast of Glenden and generally flowing south and southeast through Barna and Gabalbara country, the Isaac River is a tributary of the Mackenzie, which in turn discharges into the Fitzroy. Ludwig Leichhardt named the river, which drains a 22,364 square kilometre catchment and gives the Isaac Region its name, on 13 February 1845, "...in acknowledgement of the kind support we received from F. Isaac Esq of Darling Downs". Pastoralist Frederick Nevil Isaac owned Gowrie Station on the Darling Downs.
