Roper River
Early dry season snapshot measurements were taken on the Roper River to establish water quality and quantity conditions at commencement of baseflow conditions. The snapshot measurements are used to: 1. Refine and calibrate the hydrological model used to assess resource availability and allocations. 2. Better define aquifer recharge/discharge zones along the river, and 3. Provide a dataset of comparable flow and water quality measurements at identical periods in the annual water cycle.

14 Figure 10 Roper River Turbidity Profile May 2014 Temperature Water temperature varied between 24C and 33C, with the highest temperatures recorded downstream of significant groundwater discharge sites Mataranka Thermal Springs (33C) and Little Roper River (31C). Riverine water temperatures varied between 24C and 27C, with variations largely due to time of day the measurement was taken, and site characteristics. Figure 10 shows the temperature profile of the Roper River. Figure 11 Roper River Temperature Profile May 2014 Total and soluble nutrients Total nitrogen and phosphorus concentrations ranged from 110 to 350 g/L and 16 to 30 g/L respectively. Ammonia concentrations were low (<1 to 8 g/L) throughout the catchment, with the exception of site G9035316 on the Waterhouse River, with 155 g/L. The high concentration of NH3 at this site is unusual and could not be confirmed. Nitrate was elevated at Mataranka Thermal Spring and the Little Roper River at Mataranka Homestead. Relatively high nitrate concentrations persist downstream of the hot spring but return to < 10 g/L downstream of Elsie Homestead. Soluble phosphorus ranged from 3 to 8 g/L.
