Ord

Unregulated channels in the Ord region include the Ord, Negri, and Wilson Rivers upstream of Lake Argyle, and the Dunham, King and Keep Rivers.

Unregulated channel storage was not recognised as a water asset as it could not be adequately quantified.

Unregulated channels in the Ord region have negligible flows during the middle of the dry season (May–September), unlike the regulated lower Ord River, which receives releases from Lake Argyle for the purpose of maintaining flows in the lower Ord River. As the dry season coincides with the start and end of the reporting period, the amount of water stored in unregulated channels as at 30 June 2010 does not have a material impact on this water accounting report.

An expansion of the monitoring gauge network, and improved understanding of water levels and channel parameters is required to calculate the storage volume of river channels...
