14 Figure 11: Satellite Image taken during the wet season showing rivers and creeks (dark blue) into the swamp. Stream development in the Goyder Catchment is geologically controlled. Where rock outcrops come to the surface the streams form wide shallow channels and are often occupied by dense aquatic forests. In other areas the channels are deeper. Data from the Goyder River gauging station G8250002 located 1.5 kilometres downstream of the Old Gove Road Crossing (refer to Figure 8) indicates that the river has a mean yearly discharge of 935 million cubic metres. Figure 12 indicates runoff for the Goyder River at G8250002 and total rainfall at the rainfall recording station G8230237 which is located on the Liverpool River. Runoff is approximately 15 - 20% of the rainfall. After the wet season has finished only the Goyder River downstream of where it joins with Annie Creek and Annie Creek maintain flows throughout the dry season. This flow is sustained by the aquifer formed in dolomite (refer to Figure 7). The dry season flow in the Goyder River is provides water to the swamp during the dry season after the seasonal streams have ceased flowing (refer to Figure 13). A model was developed to predict spring flow into the Goyder River. Both Katherine and Liverpool River rainfall records were run through the model. From the results of the model it becomes clear that Katherine rainfall correlates better with Goyder River flow than Liverpool River rainfall. It is therefore assumed that Katherine rainfall is
