Seasonal Determinations

The following chart shows the increments to seasonal determinations across the major entitlement classes since 2007/08 irrigation season. The variability of the General Security entitlement classes is evident as is the end of the millennium drought through to 2009/10.

The following chart shows the average monthly seasonal determinations for each entitlement class since 2007/08. The Victorian Murray and Goulburn determinations are slightly better than SA High Security although they typically start higher. The NSW General Security entitlements have averaged just over 50% since the 2007/08 which is about 10% lower than the long term yield.
