Biennial flow reconstructions generated through multiple linear regression relationships between flow and tree-ring chronologies extending from 1600-2001 were disaggregated to weekly by identifying two-year periods in the naturalised reference flow broadly similar to that of the reconstructed flow. The weekly flow distribution of the identified naturalised reference flow period was used to construct the weekly flow. Scaling methods were used to re-introduce some of the variability in yearly flows lost during the disaggregation process. The flow data produced were verified to have broadly retained the variability and persistence of the reference flows. An ensemble of 500 flow time series for each sub-basin was generated to represent the high uncertainty inherent in the statistical relationships and disaggregation method.
