Storage Inflow Data

Inflow ML: Inflow volume that storage has received in Mega Litres

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.

Inflow data for the current water year against different climate scenarios

The scenarios for different inflow conditions were produced using the following terminology: 

  • Wet: Inflow volumes that are greater in 10 years out of 100
  • Average: Inflow volumes that are greater in 50 years out of 100
  • Dry: Inflow volumes that are greater in 90 years out of 100
  • Extreme Dry: Inflow volumes that are greater in 99 years out of 100
