As one of the few rivers in the Top End that flows all year round, the Daly River supports astounding freshwater biodiversity, including more than 90 species of fish, 8 of the 9 freshwater turtle species found in the Northern Territory, and 3 elasmobranch species of conservation significance. Many of these species, as well as the Daly River and catchment themselves, hold significant value for the Aboriginal Traditional Owners of the area.
The Daly’s water resources are attracting increasing attention from the agricultural, forestry and mining industries. This project aimed to collate existing knowledge and generate new knowledge on critical flow-ecology relationships and risk-based scenario models for key environmental assets in the Daly River, to support the sustainable management of its water resources.
The Daly River is in the Top End of the Northern Territory.

David Crook discusses how otolith chemistry can help explain and document fish life history.
The project is being led by Associate Professor Alison King at Charles Darwin University. Associate Professor King is being supported by researchers from Charles Darwin University, Griffith University, Northern Territory Department of Environment, Parks and Water Security and Northern Territory Department of Primary Industry and Resources.
This project is due for completion in December 2020.
