Macdonald River (Gunanday)
Gunanday, or the Macdonald River, is a tributary of the Hawkesbury River (Dyarubbin) that rises on on the eastern slopes of Mellong Range in the Great Dividing Range. It flows east then south of the Hunter Valley for about 120 km and into the Hawkesbury River at Wisemans Ferry. It was referred to as Lower, or First Branch in early European records. By the 1830s it had been renamed after former convict John Macdonald who had been given a land grant in the area.
