Made available via the Publications (Legal Deposit) Act 2004 (NT).; WRM Water & Environment (WRM) was commissioned by the Department of Lands & Planning (DLP) to undertake a flood study of the Todd River in the Alice Springs area. The aim of the study is to develop a 2 dimensional flood model, which allows flood flow in a complex flood plain to be modelled, to determine the extent and severity of riverine flooding in the town of Alice Springs and the Alice Springs rural area south of Heavitree Gap. The purpose of the study is to produce floodplain maps of the Alice Springs and its rural area for land use planning and counter – disaster purposes. This study is an extension of the Alice Springs Farms Area Floodplain Mapping Study (WRM, 2006), undertaken by WRM on behalf of the Department of Planning & Infrastructure in 2006 in order to develop detailed Todd River floodplain maps for the rural area south of Alice Springs.

Ratings are available for the following stream gauging stations: Station Creek at Bond Springs (CSIRO Site 64) (G0060012); Todd River at Wigley Gorge (G0060046); Charles River at Big Dipper (G0060047); Todd River at Anzac Oval (G0060009); Gillen Creek at Soil Erosion Project (G0060003); Todd River at Heavitree Gap (G0060126); and Emily Creek upstream Undoolya Road (G00600017). For a number of the above stream gauging stations, the NRETAS rating curves have been adjusted based on the results of the hydrologic and hydraulic model calibration and validation. The background to the adopted curves is given in Sections 3.4.1 to 3.4.5. To date, NRETAS has not developed rating curves to date for the Station Creek at Bonds Springs (G0060015) and Todd River at Amoonguna (G0060040) stations, however there is some gauging data available for both of these stream gauges. Table 3.3 shows details on the number of gaugings undertaken, the highest gauged stage and discharge, the highest rated discharges and the estimated highest flood discharge during the period of record at each of the stream gauge stations within the study area. Although there are some gauging data for the Station Creek at Bond Springs station (G00600015) the available data have not been considered reliable enough by NRETAS for the development of a rating curve. Similarly there is limited useful gauging data available for the Station Creek at Bond Springs (CSIRO Site 64) gauging station (G0060012) and the Gillen Creek at Soil Erosion Project gauging station (G0060003), and hence the NRETAS rating curves for these gauges are considered unsuitable for use in hydrologic modelling. The Amoonguna Gauge is only suitable as a water level station because most flood flows leave the Todd River channel upstream of this gauge. Hence, a rating curve has not been derived for this station. Figure 3.2, Figure 3.3, Figure 3.4, Figure 3.5 and Figure 3.6 show the adopted rating curves for Todd River at Wigley Gorge, Charles River at Big Dipper, Todd River at Anzac Oval, Todd River at Heavitree Gap and Emily Creek Upstream Undoolya Road stream gauging stations.
