 It comprises the Ord River and Parry Lagoons nature reserves, with some additional land.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.
