1:100,000 scale map of the native vegetation in the Nothern territory, Project report to NT NRMB, Luke Peel, 2009. Technical Report 08/2009D.
This project was successful in researching and developing a suitable method by which native vegetation can be mapped at a refined scale in a more rapid and cost effective way than previous methods allowed. An intermediate map product of the Daly Catchment was produced at 1:100,000 scale depicting broad structural vegetation community types.

Seasonal tidal and freshwater chemistry of the south Alligator and Daly rivers
Chappell, John and Ward, Peter. 1985 in Coasts and Tidal Wetlands of the Australian Monsoon Region, eds K.N. Bardsley, J.D.S Davie and C.D. Woodroffe, Australian National University North Australia Research Unit Mangrove Monograph no.1, Darwin.
Describes major changes in inorganic chemical properties of two large tidal rivers, the Daly and the South Alligator, through the wet-dry season cycle. Wet season water quality is determined largely by flood runofffrom the catchment. Dry season chemistry is affected by turbulent diffusion of seawater upstream.

Landscape design for maintaining ecosystem services in tropical agricultural landscapes:
The response of fauna and flora to landscape mosaics and implications for land clearing policy.
Report to Land and Water Australia. Dept. of Natural Resources, Environment, The Arts and Sport, Darwin. Griffiths, A.D. et al., 2009
Project TRC07 - Managed through Tropical Savanna CRC
"To investigate the relationship between fragmentation, habitat loss and terrestrial biodiversity we conducted extensive surveys in the Douglas Daly region of the Top End of the Northern Territory in 2007 and 2008. This study shows that the impacts of land clearing on biodiversity are substantial at the scale of individual properties (represented as “landscapes” in this study), even if they retain some areas of native vegetation."

Sediment sources and channel dynamics, Daly River, Northern Australia
R.J. Wasson, L. Furlonger, D. Parry, T. Pietsch, E. Valentine and D. Williams, 2009.
Geomorphology doi:10.1016/j.geomorph.2009.06.022
The Daly River occupies a mainly undisturbed large catchment in the Australian wet-dry tropics. Concerns about possible increased sediment input to the River from clearing and cropping has motivated this study of fine sediment sources.

Aspects of Modelling the Daly River
Valentine, Eric M.
In: Proceedings of Water Down Under 2008; pages: 875-884. Lambert, Martin (Editor); Daniell, Trevor M (Editor); Leonard, Michael (Editor). Modbury, SA: Engineers Australia ; Causal Productions, 2008.
"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.

Groundwater in the Daly Basin
Tickell, S. 2009, Technical report no. 27/2008D
The Daly Basin is a geological basin that contains two major aquifers in limestone formations. Groundwater cannot move between the aquifers as they are separated by impervious siltstone formations. Significant recharge to the aquifers occurs in most years. The groundwater drains to the Daly River and its major tributaries, causing them to flow all year round. These permanent treams support distinctive ecosystems both within the river and along its banks. The aquifers store and transmit significant volumes of groundwater. Quantities suitable for irrigation can often be extracted from individual bores. There is a small but increasing agricultural industry. Water allocation plans are currently being developed to ensure that both surface waters and groundwaters are used sustainable. Maintenance of dry season river flows and of the ecosystems that they support are the main guiding principles behind water management in the basin.

River Stability Issues in Northern Australia
Valentine, Eric M. 2006, in 30th Hydrology & Water Resources Symposium: Past, Present & Future. p. 568 -575
The Northern Territory Government plans to convert pastoral leases in the Daly River region to agriculture. Prior to this development it is important to understand the sediment dynamics of the system and the potential impacts on the river of water abstraction for irrigation. There is considerable debate about the effects that potential development of the river basin may have on the river channel. It has been suggested that there has been considerable siltation in the estuary since 1880, and recent observations of the channel indicate that there are instabilities in the channel plan-form. The question as to whether these instabilities are driven by hydrological or anthropogenic influences is crucial to the decision on future development and how it should be managed.

Fishing the 'big rivers' in Australia's Northern territory: market diversification for the Daly River
Carson, D. Schmallegger, D.
2009 CABI (ISBN 9781845934682)
This e-book chapter is concerned with the fishing assets (including rivers, estuaries, lakes and billabongs) of the Northern Territory (Australia) and how their use might reflect on innovation in the tourism destination system. Specifically, the chapter examines the level of diversity in the fishing tourism marketplace in the Northern Territory. The research considers two aspects: the first is the diversity of trips taken to the Northern Territory which feature fishing as an activity (trip patterns); and the second is the industry response to the market in terms of the structure of the product mix and marketing strategies (industrial organization) of one of the big-river fishing destinations in the Territory's Top End. Data from the Northern Territory Travel Monitor (2000-04) are used to describe trip patterns and a case study of the Daly River is used to analyse industrial organization.
