Mary River


The Mary River Flood Plains are approximately 100km east of Darwin and have a catchment area of about 7700 kn12 (Woodroffe 1993). The headwaters are approximately 18Skm inland. The southeast corner of the catchment includes Coronet Hill and a sandstone/siltstone plateau. Further to the south west in the Pine Creek region are undulating to rolling hills (includes strike ridges) of greywacke, sandstone and siltstone. The west side of the catchment includes undulating to rolling granite rises with some rugged hills. The McKinlay River joins the Mary River just south of the Arnhem Highway. From here the river divides into a series of streams and billabongs which are only connected in the Wet season.
