All water in accounts can be accessed immediately.

Now that general security allocations have past 20pc of entitlement, re-crediting of water to the environmental accounts has commenced.

Lower Darling Valley general security license holders remain at 50pc of entitlement.

The NSW Department of Water and Energy has also advised that all inter-valley trades must be lodged by close of business on 31 May 2009.

The closing date for interstate trades will be notified later.
