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 2023/2024 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).
