About Commonwealth environmental water
As part of a suite of national water reforms, the Australian Government created the Commonwealth Environmental Water Holder through the Water Act 2007:
“The functions of the Commonwealth Environmental Water Holder are to be performed for the purpose of protecting or restoring the environmental assets of the Murray-Darling Basin ... so as to give effect to relevant international agreements.”
Commonwealth water holdings are the direct result of government purchases of entitlements and a substantial investment in more efficient water infrastructure in the Murray Darling Basin. Refer to: Rural water.
The planning, prioritisation, use and monitoring and evaluation of Commonwealth environmental water is informed by a range of stakeholders including the Department of the Environment and other Commonwealth and State government agencies, scientists, catchment and local natural resource management agencies, environmental water advisory groups, water user associations, Indigenous communities and local landholders.
Following the ratification of the Murray Darling Basin Plan on 21 November 2012, the Commonwealth Environmental Water Holder’s decisions on water use, carryover and trade have been made in the context of, and consistent with, the Basin Plan’s Environmental Watering Plan, and annual priorities.
As at 31 July 2015, the Commonwealth environmental water holdings total 2,366,043 megalitres of registered entitlements with a Long term average annual yield of 1,640,163 megalitres.

The figure below shows water availability and water use as at 30 June each year from 2008-09 to 2014-15, and as at 31 July for 2015-16. As at 31 July 2015, over 4,639 gigalitres of Commonwealth environmental water has now been delivered to rivers, wetlands and floodplains of the Murray-Darling Basin.
For detailed information on water delivered in each catchment of the Murray-Darling Basin, see the Water use page for each individual Catchment.
