Definition
The Kedumba River is a perennial watercourse situated in the Blue Mountains region of New South Wales, Australia. It is a tributary of the Coxs River, which ultimately forms part of the Hawkesbury–Nepean catchment.
Overview
The Kedumba River originates on the eastern slopes of the Blue Mountains, near the village of Katoomba, and flows generally southeast through rugged terrain before joining the Coxs River near the locality of Glenbrook. The river lies within the boundaries of the Blue Mountains National Park and contributes to the region’s ecological diversity, supporting native flora and fauna. It is part of a network of streams that drain the western side of the Great Dividing Range in this part of New South Wales.
Etymology/Origin
The name “Kedumba” is believed to derive from an Aboriginal word of the local Gundungurra or Darug peoples, although the precise meaning is not definitively recorded in published sources. The term may refer to a characteristic of the river or the surrounding landscape, but accurate information is not confirmed.
Characteristics
- Source: The river rises from runoff and springs on the eastern slopes of the Blue Mountains, at an elevation of approximately 900 m above sea level.
- Course: It flows for roughly 15 km (estimated) through steep gorges and forested valleys, traversing sandstone formations typical of the region.
- Mouth: The Kedumba River discharges into the Coxs River near Glenbrook at an elevation of about 150 m.
- Hydrology: As a perennial stream, it maintains flow throughout most of the year, with higher discharge during the Australian summer rain season.
- Ecology: The river’s riparian zones support a variety of endemic plant species, such as Eucalyptus forest types, and provide habitat for wildlife including the platypus (Ornithorhynchus anatinus) and several freshwater fish species.
- Management: The waterway lies within protected lands managed by the New South Wales National Parks and Wildlife Service, and its water quality is monitored as part of the broader Hawkesbury–Nepean basin management program.
