Inter-Valley Trade

Inter-Valley Trade accounts (IVT) reflects the net balance of surface water volume that has been temporary traded or tagged traded out of a particular water source at any point in time. All categories of licence permitted to trade can affect the IVT balance. 

These IVT's are in place for numerous reasons, including:

• Preservation of the Environment
• Keeping enough water in particular rivers and valleys
• Reducing unseasonal high flows

The main inter-valley trade restrictions are between:

• The Murrumbidgee and Murray River (Murrumbidgee IVT)
• The Barmah Choke, in the Barmah-Millewa Forest (Barmah Choke IVT)
• The Goulburn to Murray River (Goulburn IVT)
• The Lower Darling to Murray River (Lower Darling IVT)
