Inflow ML: Inflow volume that storage has received in Mega Litres (ML)
POE: The probability of exceedance describes the likelihood of a specific volume being exceeded in the given time period. E.g. 90% POE means that 90 out of 100 times we would expect higher inflow volumes. A 50% POE is equal to a median average.
% Average: Mean Average - The value obtained by dividing the sum of all inflow volumes by the number of years data is available. Therefore a 50% mean average does not equal a 50% POE.
The inflow statistics are based on historical flow records that have been adjusted to match climate conditions observed since 1975.

Inflow data for the current water year against different climate scenarios
Climate Scenarios
The scenarios for different inflow conditions were produced using the following terminology:
- Wet Scenario : Inflow volumes that are greater in 10 years out of 100 (10% POE)
- Average Scenario : Inflow volumes that are greater in 50 years out of 100 (50% POE and not average)
- Dry Scenario : Inflow volumes that are greater in 90 years out of 100 (90% POE)
- Extreme Dry Scenario : Inflow volumes that are greater in 99 years out of 100 (99% POE)
In the inflow graphs below actual inflow data is compared to these four scenarios. Inflows are measured in Giga Litres (GL).
