9.6 Overbank flood return to river channel
Supporting Information
Overbank flood spilling may have occurred in the Sydney region during the 2010–11 year. However the measurement of overbank flood spilling is very difficult to quantify and therefore could not be accounted for with data that were complete, neutral and free from material error. As a result, overbank flood spilling in the Sydney region is not recognised in the Water accounting statements. Its omission is not considered to have a material impact on the surface water store.
