"Observations suggest that there has been considerable siltation in the estuary since 1880, and there are indications that there are instabilities in the channel plan form. The question as to whether these instabilities are driven by hydrological or anthropogenic influences from previous limited agricultural development is crucial to the decision on future development and how it should be managed. A numerical model of the hydrodynamics and morphology of the Daly River is being constructed to help determine the transport and fate of sediments on the floodplain and in the channel. This paper presents an overview of some model approaches being applied to the Daly River."

River floodplain - foodweb subsidies
Stuart Bunn
This project will describe how seasonal flooding of rivers over their floodplains contributes to changes in the foodweb as feeding grounds for aquatic fauna expand and contract and determine how some current land management practices are affecting the floodplain food webs of northern rivers. The primary focus for the project will be the Mitchell River floodplain in Queensland. Some components of the project will also take place in the Daly River floodplain in the Northern Territory.

Gamba Grass Management in the Lower Daly
Wangamaty Landcare Co-ordinator - Joye Maddison
The Wangamaty Landcare Group and the MalakMalak rangers find and spray Gamba grass annually in the wet season and also identify & treat other grassy weeds. At the same time they to support and encourage other landholders to control and monitor their Gamba sites. The management strategy is to identify & treat ‘outliers’, follow-up at previously treated sites, survey and then tackle larger sites. Crucial to the Gamba management strategy is collecting and recording data for every site and every single outlier plant treated. This information is then passed on to DNRETAS Weed Management branch.
