The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

A detailed analysis of aquifer systems in the Broken Hill Managed Aquifer Recharge priority areas has clarified our understanding of key components of the aquifer systems. Of the priority areas examined in detail, the aquifers located in the Darling Floodplain are considered to have the greatest potential for developing Managed Aquifer Recharge (MAR) options and for hosting significant volumes of previously undefined fresh and brackish groundwaters with low levels of allocation, thereby assisting the larger strategic effort aimed at identifying significant water-saving measures for the Darling River system.

In early autumn 2006 (14th March to 4th April), Geoscience Australia conducted a field survey to investigate the major processes controlling water quality in Wellstead Estuary, Gordon Inlet and Beaufort Inlet. This project aimed to address critical knowledge gaps in understanding the impact of sediment-water interactions on water quality in each estuary, in particular, to identify the major controls on nutrient abundance and availability. The impacts of sediment-water interactions on overall water quality took into account: 1. shallowness of the estuaries and long water residence time; 2. productivity of microbenthic algae; and 3. the type of aquatic plant growth. Recommendations for the future management of these estuaries included: 1. Reducing nitrogen loads from the catchments of Wellstead Estuary and Gordon Inlet, and reducing the phosphorus loads from the catchment of Beaufort inlet; 2. Monitoring the abundance of macroalgae in Wellstead Estuary, the abundance of macrophytes in Gordon Inlet and the water column Chl-a concentrations in Beaufort Inlet.

In April 2005, Geoscience Australia (GA) conducted a field survey of the waterbodies of the Torbay catchment drainage system. The Torbay Catchment Group and the Western Australian Department of Environment commissioned this study in order to address critical knowledge gaps in their understanding of the major components of the nutrient budget. In particular, the role of benthic nutrient fluxes, their magnitude, and total benthic nutrient supply to the water column for phytoplankton growth. The waterbodies studied were Torbay inlet, Lake Powell, Marbellup Brook and Lake Manarup. The key findings of this study were: 1. the sediments are a major source of nutrients to the water column of all waterbodies; and 2. denitrification, nitrogen fixation and benthic photosynthesis are critical processes influencing overall water quality.

Hermannsburg Mission Station is situated 80 miles west of Alice Springs. In the winter of 1951, Pastor Albrecht, the Superintendent of the Mission, made a request for government assistance in the location of underground water supplies. Early in October, G.F. Joklik and S.A. Tomich, of the Bureau of Mineral Resources, spent five days on the station and picked seven sites for possible water bores. Throughout this report, reference is made to the accompanying map.
