New South Wales data are for Murrumbidgee and Murray regions only. There is no information available in water audit monitoring (WAM) for other NSW Irrigation Trusts.

The New South Wales Murrumbidgee volume represents the diversion allocation associated with bulk irrigation conveyance licence allocation within the Coleambally and Murrumbidgee irrigation areas. These conveyance licences are held by irrigation trusts to account for losses within their distribution systems.

New South Wales Murray volume represents the diversion allocation associated with the regulated river conveyance allocation that accounts for losses in the Murray region.

The entitlement class or purpose associated with the line item is not available in Australian Capital Territory, Queensland and South Australia.

No information is available for Victoria. See Line item 14.7.9.7 Allocation diversion of regulated flows – other lumped holders.
