 The southern part of the site is dominated by Parry Creek, including 20 km of seasonal creek and an alluvial floodplain which is flooded during the wet season.It dries out quickly in the dry season, except for waterholes associated with incised channels and claypans.The southern, or upstream, part of the floodplain is freshwater, while the northern, or downstream part, is either regularly flooded with saltwater or contains saline soils.
