16 Figure 13: Indicates the dry season flow in the Goyder River each year. similar to what falls on and recharges the dolomite aquifer, which in turn maintains spring inflow into the Goyder River. The model was used to extend the spring inflow record from the short period for which flow data is available for Goyder River G8250002 1966 to 1987, to the period for which rainfall exists for Katherine (since 1884). The predicted flows are given in Figure 14. The model predicted that flows ranged from as low as 0.6 cubic metres per second to as high as 8.7 cubic metres per second. The data also indicated that spring flows for the period for which the gauging station was open prior to this study 1966 to 1987, were significantly higher than those that occurred over the previous fifty years or over the following 10 years.
