Description

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.

The wet season 'builds up' in September/October and showers may fall up until May with a yearly average total of 130().1 mm. The greatest difference in rainfall between years is 852 mm. With 1949.1 mm in 1995, a 'wet' year and l097mm in 1992, a comparatively 'dry' year. The distribution of the rain across the Wet season varies between years also. For example in 1988/89 the Wet season had a heavy early and heavy late season rain. Whilst in other years especially 1990/91, (refer Figure J) most rain for the season fell in the mid Wet Season (Dec,Jan).
