The dominant direction of flow in the basin is southwards toward Heavitree Gap along the axis of the basin, that is generally parallel to the Todd River. There is a lack of monitoring bores around the edge of the basin, but the limited potentiometric data available and the distribution of TDS indicate that there is flow from the weathered rock areas and the silty aquifers into the more highly transmissive sand aquifers of the basin. This probably has a negligible effect on the water balance, but a significant effect on the salt balance. This can be seen on the eastern edge of the basin where highly permeable aquifers abut the low transmissivity bedrock 39
