Rainfall across the Richmond River WMA was below average in 2004-05, at around 92% of long term average rainfall (see Figure 2) and the 10 year average was 94% of the long term average.
The total volumes of water available and supplied from water resources in the Richmond River WMA are shown in Table 2.

The following information becomes apparent from Table 2.
The data for this water balance is highly variable with most of the surface water information for regulated areas obtained from recorded data and estimates, whilst surface water data for the unregulated areas and groundwater information is less detailed as no modelling data was available. The data for this water balance was predominantly category A (Table 3), indicating that the majority of the data was of a high standard. The overall reliability for the catchment was estimated as ±45%.
The categories used for the breakdown of water consumption are as per Table 2.9
of the Water Account 2004-05. "Other" in respect of the estimated water consumption
comprises water use within the following industries:
