 It lies downstream of two large impoundments on the Ord River, Lakes Argyle and Kununurra, which have had a major impact on the river’s hydrology through changing its flow pattern so that there are now constant flows through the dry season.In effect, the lower Ord has been transformed through flow regulation at the dams from a ‘dry tropics’ to a ‘wet tropics’ river.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.
