Allocation and availability
Allocation and resource outlooks
The NSW Department of Primary Industries (DPI) Water makes
available water determinations (AWDs) or allocation announcements
from the commencement of the water season on 1 July. A fact sheet
explaining how water allocations are made is available here.
A presentation given by Brian Graham from the NSW Office of
Water at the RGA Water Trade Workshop in July 2016 is available
here. This explains that General
Security allocations are calculated by determining the total
resources available - storage plus tributary plus minimum storage
inflows - and subtracting the total supply requirements such as
river operations, town, stock and domestic and high security.
Allocation announcements are generally made on the first and
15th (or next business day) until general security allocations
reach 100 percent or mid-April, after which time it is assumed
further inflows will contribute to higher opening allocations in
the next year. Murray Irrigation passes this allocation onto
customers with announcements sent out via our Talking
Water subscription on the same day. Murray Irrigation also
publishes these announcements on our website here.
To assist with forward planning, DPI Water prepares an
indicative water availability outlook usually in March and May
preceding the commencement of the water season and potentially
again in August if needed.
Water availability in Murray Irrigation
Murray Irrigation customers are issued allocations against their
contractual water rights (water entitlements held within Murray
Irrigation) in line with those announced by DPI Water.
Murray Irrigation customers may also purchase allocation on the
temporary water market for use within Murray Irrigation, or they
may sell allocation within or outside Murray Irrigation (see water
market information below).

Water holders in the NSW Murray have access to
both permanent and temporary water markets.
Murray Irrigation shares, water entitlements and
delivery entitlements can be transferred between landholdings, and
water entitlements can be transferred to and from any person
including non-Murray Irrigation WAL licenses as long as NSW Office
of Water (NOW) approves the trade. These may be sold with or
without associated allocation. Murray Irrigation's fact sheet on
permanent trade is available here.
Licence holders may access allocation on the
temporary market. The NSW Murray can access allocation from within
the valley (intra-valley), or from connected valleys in NSW
(inter-valley), or from connected valleys in other states
The following markets are available to NSW
Murray water licence holders within the stated limits.
